The control panel of an audiosystem of standard complete set Bose
Features of functioning of system in a radio reception mode
The general information
Radio receiver functioning probably only in positions ON and АСС the ignition lock.
Cleanliness of reproduction is influenced by such factors, as capacity of a signal, removal from the nearest repeater, presence nearby bridge farms, high-rise buildings and other sources of passive hindrances.
The most typical source of active hindrances is the mobile phone which use in car salon can make essential impact on quality of radio reception.
It is necessary to pay attention of the reader also to that fact that some physical features of distribution of radio-waves (both frequency, and peak modulation), are capable to influence cleanliness of their reception in a moving vehicle irrespective of the fact of presence of hindrances and level of used equipment.
Remember that the moving car is far not ideal object for reception of radio-waves. Owing to moving of a condition of reception continuously change. From time to time in immediate proximity there are large structures and the heights, making negative impact on distribution of electromagnetic radiation, — even moving in the neighbourhood or towards a vehicle can influence quality of reception.
Features of distribution of radio-waves of an ultrashort range (FM)
At radio receiver use in range FM limiting removal from the nearest repeater is the distance of 40-48 km.
In a monophonic mode range of reception can increase a little in comparison with стереофонией. Presence of sources of passive and active hindrances can influence quality of radio reception even within a 40-kilometre zone. Capacity frequency-modulated (FM) a signal mainly is defined by removal from a source a principle of distribution of ultra-short waves is similar to a principle of distribution of light so, for example, they possess ability to be reflected from various objects.
Attenuation and displacement of bearing frequency: In process of removal of the car from a source of radiation of radio-waves the signal tends to attenuation and displacement of bearing frequency.
Static hindrances: As a result of rendered by large objects (buildings, hills, etc.) influences at reception of radio signals can arise the high-frequency hindrances which intensity can be lowered by twisting of level of reproduction of high frequencies (TREBLE).
Cross hindrances: In view of ability of ultrashort radio-waves to reflexion in some situations there can be overlays of signals from various radio stations that leads to faults in reception and sporadic losses of a sound.
Features of distribution of the average, long and short radio-waves applied in a range (АМ)
Such radio-waves possess ability not to be reflected (to get through their distributions meeting on a way objects) but to be reflected from an ionosphere of the Earth. Told means that these signals also are subject to an interference on a way from a source to the receiver.
Attenuation: reception Attenuation in a low-frequency range can arise at car movement under overpasses and road outcomes, and also among high-rise buildings, except that, short decrease in level of reception can be caused by turbulent indignations of an ionosphere even in flat district.
The most typical example of the static hindrances, making essential impact on cleanliness of radio reception in range АМ lightning discharges, and also high-voltage transmission lines and even светофорные objects are.
Features of some constructive decisions
Signal reception in VHF a range is often accompanied by the strong noise connected with good reflexion of ultra-short waves from various obstacles. The system of double reception based on two aerials is applied to improvement of quality of reception. The first aerial represents the usual telescopic aerial. The second aerial — wire type — is pasted on back glass of the car. The system is automatically switched to that aerial which provides at present the best quality of reception.
In a recorder prefix the head from никележелезного an alloy (пермаллой), providing high cleanliness of reproduction in a range of high frequencies is applied. Noise level decrease it is provided also at the expense of system application шумоподавления Dolby NR, — filters of mark Dolby NR are made on corporation Dolby licences, inscription Dolby NR and a symbol in the form of double D are trademarks of this corporation. The contour of automatic adjustment of intensity of sounding provides additional improvement of quality of reproduction in a range of low frequencies both in a radio reception mode, and at listening of magnetic and laser records.
Inclusion of a food / sounding volume control
Turn the ignition key in position ON or АСС, then press button ON-OFF/VOL at the left on audiosystem control panels (the Control panel of an audiosystem of standard complete set Bose see an illustration), — the system will automatically pass in that mode of reproduction (a radio receiver / CD-player tape recorder/) in which it has been disconnected (if the cartridge or a compact disc are not loaded into the corresponding loader, the radio reception mode is activated). Repeated pressing the button leads to system switching-off.
Sounding volume control is made by handle ON-OFF/VOL rotation.
Adjustment of a timbre of sounding and balance of a sound
Balancing of distribution of a sound and adjustment of a timbre of sounding
Switching of modes adjustments BASS (basses), TRE (high frequencies), FAD (balance between forward and back loudspeakers) and BAL (the balance between the right and left loudspeakers) is made by means of button AUDIO on the right on the audiosystem control panel (the Control panel of an audiosystem of standard complete set Bose see an illustration), — on the display screen will be highlighted an inscription of the corresponding maintenance.
The order of switching of modes — see an illustration Balancing of distribution of a sound and adjustment of a timbre of sounding. Actually adjustment, after a choice of a demanded mode, is carried out by means of two buttons and.
Later 10 seconds system will automatically return to a usual mode of reproduction (radio / CD-player tape recorder/). Compulsory return to a mode of reproduction after realisation of necessary adjustments can be made a way нажимания on button AUDIO demanded quantity of times.
Rules of use of system in a radio reception mode
Switching of a frequency range (FM1/FM2/АМ) is made by means of button FM/AM on the audiosystem control panel (the Control panel of an audiosystem of standard complete set Bose see an illustration), — at нажимании to the given button at the included ignition (ON or АСС) the radio receiver will automatically pass to reproduction of that radio station on which frequency it has been switched off.
Besides to result will result pressing button ON-OFF/VOL if in corresponding loaders there is no cartridge or a compact disc.
At нажимании on button FM/AM during playing of magnetic or laser record the given reproduction automatically will interrupt also system will pass in a radio receiver mode on frequency of last chosen radio station.
Высвечивание on the screen of the display of symbol ST means that reception is conducted in a stereophonic mode, — at decrease in signal strength the system is automatically switched in monophonic reception.
Mode of manual adjustment
Manual adjustment of frequency of radio reception is carried out by means of buttons and on the right on the audiosystem control panel (the Control panel of an audiosystem of standard complete set Bose see an illustration). Pressing of buttons changes frequency of an accepted signal to one step upwards or downwards. For fast viewing of frequencies keep the corresponding button pressed during more than 0.5 seconds.
Radio receiver adjustment should not be made by the driver during movement!
Mode of search / of viewing
Short-term нажимание on one of buttons of switch SEEK/SCAN or at the left on the audiosystem control panel (the Control panel of an audiosystem of standard complete set Bose see an illustration) leads to inclusion of a mode of automatic search of active radio stations. Viewing of frequencies is made as their increase or reduction depending on what of buttons has been pressed. At revealing of active frequency search stops also system passes in a broadcasting mode, — in case of need press the corresponding button once again.
Keeping of any of mentioned above buttons pressed within more than 1.5 seconds leads to activation a mode of viewing of a range of radio frequencies (see above). In the given mode the system automatically looks through all range of frequencies of the tuner, doing 10-second demonstration stops on each of active channels. The exit from a mode of viewing with a stop on the chosen frequency is made by repeated pressing of the same button.
Function of storing of radio stations
Adjustment of a radio receiver for favourite radio stations
The radio receiver allows to fix on six radio stations in each of ranges of frequencies (FM1/FM2/АМ).
- By means of buttons TUNE or SEEK/SCAN (see above) be adjusted on desirable station.
- Press and keep pressed before reproduction of a short sound signal any of six buttons of storing / of a choice of favourite radio stations in the bottom part of the control panel of an audiosystem (the Control panel of an audiosystem of standard complete set Bose see an illustration), — at нажимании on the button reproduction should stop.
- After end of process of storing on the display screen the indicator of the corresponding channel (for example, ch2 — Adjustment of a radio receiver for favourite radio stations see an illustration) is deduced, and reproduction renews.
- Installation of the remained six channels is made in a similar manner.
At switching-off of a food of a radio receiver or выбивании a safety lock memory of a radio receiver is erased. In this case it is necessary to repeat procedure of adjustment for favourite radio stations.
Rules of use of system in a mode of reproduction of a magnetic recording
Establish the ignition key in position «АСС» or «ON» and horizontally fill the cartridge in кассетоприемник, — the cartridge will automatically be involved in a nest by the loader.
It is not necessary to apply force at cartridge refuelling! Right after tape loadings record reproduction will begin, — if till the moment of loading of the cartridge the system worked in a mode of broadcasting or playing of laser records, mode change also will occur automatically.
If to make switching-off of system by pressing button ON-OFF/VOL and not to take the cartridge from кассетоприемника at repeated inclusion of a food reproduction of the interrupted record from a magnetic tape will proceed.
Activation of reproduction of a magnetic recording (TAPE)
Pressing button TAPE (the Control panel of an audiosystem of standard complete set Bose see an illustration) at the loaded cartridge and the switched off system leads to activation of a mode of reproduction of a magnetic recording.
Pressing button TAPE at the loaded cartridge at the activated mode of broadcasting or reproduction of laser records will lead automatic switchings of a mode and to the beginning of reproduction of a magnetic recording.
By means of the same button it is possible to pass in a mode of normal reproduction from modes of the accelerated scrolling (FF/REW) and automatic search (APS FF/APS REW).
Function accelerated forward (FF) and returnable (REW) film rewinds
Activation of a mode of the accelerated rewind of a film in a corresponding direction is made by pressing the button or audiosystem control panels, — in the right sector of the screen of the display the corresponding pictogramme will be highlighted. For return to a mode of normal reproduction press on туже the button once again, or take advantage of button TAPE (see above).
Function of search of the beginning of records (APS)
Function APS allows to pass automatically to the beginning of records.
At нажимании on the button (APS FF) during reproduction there is a transition to the beginning of the next record on a magnetic tape. For the admission of several records press button APS FF demanded quantity of times (possibility of the admission to 9 records is supposed).
Unitary pressing the button (APS REW) allows to pass to repetition of reproduction of current record. Repeated pressing the button carry out transition to the beginnings of higher records.
At activation of mode APS in the right sector of the screen the inscription of the corresponding maintenance (FF or REW) is highlighted.
For an exit from a mode of search and return to a mode of normal reproduction press on туже the button once again, or take advantage of button TAPE (see above).
Function APS can not work in following cases:
- Record level is too low;
- On a tape informal conversation is written down;
- Intervals between records make less than 4 seconds;
- Pauses between records too long;
- Record goes without intervals;
- The pause is filled by a strong noise background.
Change of a direction of scrolling of a tape (PROG)
Pressing button PROG leads to switching of a direction of scrolling of a magnetic tape.
Automatic switchings of a direction of rotation tapes (automatic reversion) occurs at its end.
By pressing button PROG in a mode of accelerated rewind FF or REW there is a return to a mode of normal reproduction.
System of suppression of noise Dolby NR
If the magnetic recording is coded on system Dolby NR for elimination of high-frequency noise of a tape press the button «DOLBY NR», — on the display screen the corresponding symbol will be highlighted.
Filters of mark Dolby NR are produced under corporation Dolby licence. Inscription Dolby NR and double D are trademarks of this corporation.
Use of the metallized and chromeplated tapes
At use of the cartridge of type Metal or Chrome the system is automatically switched in a mode of the raised quality of reproduction.
Press the button of emission of the cartridge, — magnetic recording reproduction stops, and the cartridge jumps out from кассетоприемника with simultaneous switching-off of giving of a food.
At playing of cartridges with the metallized or chromeplated tape the player automatically is switched to a high-quality reproduction mode. During playing of such tapes the corresponding indicator burns.
Safety measures at use of a cassette player
- To keep high quality of sounding use cartridges with duration of reproduction less than 60 minutes.
- It is not necessary to leave the cartridge in a player. Store cartridges in protective covers and do not suppose hit on them of a direct sunlight, heat, a moisture and magnetic materials.
- At heating from solar radiation the cartridge can be deformed and become unsuitable for use.
- Do not use the cartridge with lagging behind labels which can get stuck in a player.
- If the tape in the cartridge was weakened, insert a pencil into one of перемоточных naves and densely reel up a tape on the cartridge platen. The weakened tape can be restive that will worsen quality of its sounding.
- Eventually reading out, tightening and capstans become soiled fragments of a magnetic layer of a passing tape. Such polluting stratification leads to easing and reproduction distortion in view of what heads should be cleared periodically by means of the special cartridge.
Rules of use of system in a CD player mode
Turn a key in position ON or АСС and fill a compact disc in a loading crack of the disk drive with the title party upwards, — the disk should be involved automatically by the loader and start to be lost.
Right after disk loadings on the display screen the quantity of the paths written down on it and reproduction time is deduced.
If at the moment of loading the audiosystem worked in a mode of broadcasting or reproduction of a magnetic recording, mode change will occur also automatically.
Do not try to push at all a disk in the disk drive force!
If to make switching-off of system by pressing button ON-OFF/VOL and not to take a disk from the disk drive at repeated inclusion of a food reproduction of laser records will begin with the established disk.
Without application of transitive adapters disks of two standards can be loaded into system: 4-3/4 inches (12 sm) and 3-1/8 inches (8 sm).
Activation of reproduction of laser records
Models without CD-changer
Нажимание on CD/CHG button (the Control panel of an audiosystem of standard complete set Bose see an illustration) at the switched off audiosystem and the loaded compact disc leads to start of reproduction of laser records.
If at the moment of pressing the button at the loaded disk the system worked in a mode of broadcasting or magnetic recording reproduction, there will be a change of a mode and reproduction of records will begin with a disk.
Models with CD-changer
At connected to system of CD-changer with the disks loaded into it, the filled disk drive of a player and the switched off food pressing CD/CHG button leads to activation of that mode in which the system has been stopped.
If at the moment of pressing the button the system worked in a mode of playing of laser records from a disk filled in the disk drive of a player, current reproduction will stop also system will be switched in a changer mode. At the opposite entering data fairly return.
If the disk is filled only in the player disk drive, and the changer loader is empty, pressing CD/CHG button at the switched off food of system will lead to player activation. If at the moment of pressing the button the player worked, reproduction will stop, and on the display screen in a flashing mode message NO DISC will be deduced. After a while the system will return again to reproduction of the interrupted record from the player of a disk loaded into the disk drive (message NO DISC from the screen will disappear).
If by pressing CD/CHG button at the switched off food the changer loader is filled only, there will be an activation of the last.
Pressing CD/CHG button at empty loaders as player, and changer leads to a conclusion in a flashing mode on the screen of the display of message NO DISC.
If at the moment of pressing the button at the loaded player and-or a changer the system worked in a mode of broadcasting or magnetic recording reproduction, there will be a change of a mode and reproduction of laser records will begin with player or changer disks.
Function of the accelerated scrolling in forward (FF) or a returnable direction (REW)
Pressing the button or audiosystem control panels will result to reproduction of records with the accelerated scrolling in a corresponding direction. At release buttons the system comes back in a mode of normal reproduction.
Function of search of the beginning of records (APS)
Function APS allows to pass automatically to the beginning of records.
At нажимании on the button (APS FF) during reproduction there is a transition to the beginning of the next record on a disk. For the admission of several records press button APS FF demanded quantity of times (at пропускании last path on a disk the system passes to the beginning of the first).
Unitary pressing the button (APS REW) allows to pass to repetition of reproduction of current record. The further pressing the button carry out transition to the beginnings of higher records.
Change of the scheme of reproduction of paths (PROG)
Pressing button PROG leads to switching of the scheme of reproduction of the paths written down on a disk.
At absence on the screen of the display of any labels of a path will be reproduced consistently as their record on a disk.
The conclusion to the screen of a label 1 means that the scheme of reproduction of unique (current) record in its continuous repetition is chosen.
At высвечивании messages RANDOM of a path will be is made in a casual order that does not exclude probability of repetition of the same record twice.
At compact disc extraction the mode of consecutive reproduction of paths (labels are absent) is automatically established.
Compact disc extraction
Press the button of emission of a disk, — reproduction stops, and the disk is pushed out by the loader with simultaneous switching-off of giving of a food.
If the disk pushed out by the loader is not taken in time, after a while there will be an automatic retraction in the disk drive.
The indicator of presence of a disk in the disk drive (CD IN)
CD IN message is displayed the display at the included food and loaded into the disk drive of a player a compact disc.
Safety measures at CD player use
- In cold and rainy weather owing to increase of humidity of air there can be refusals of functioning of a player, — take a disk from the disk drive and carefully ventilate and dry a player.
- At movement on a rough road covering there can be admissions of reproduction of laser records.
- Player refusals can occur also at excessive to a heat in car salon, — include the conditioner of air and lower temperature.
- Do not suppose influence on compact discs of a direct sunlight.
- Quality of reproduction of laser records appreciably depends on a compact disc condition, — try not to suppose occurrence on a surface of a disk of scratches, fingerprints, dirt touches, etc.
- Use 8-santimetrogvogo the transitive adapter can lead to a system exit out of operation.
- The system does not give possibility of listening of the paths which have been written down on compact discs of the standard of CD-R.
Rules of use of system in CD-changer mode
Installation / shop extraction
Fill a disk in shop of CD-changer with the title party upwards (see more low).
Insert shop into a reception nest of CD-changer and close сдвижную a cover. For shop extraction it is necessary to press button EJECT.
Order of loading / of extraction of disks
Develop a disk the title party upwards and accurately fill it in any of free nests of shop. At the correct there will be a pushing out outside of marked with an asterisk white рычажка.
For extraction of a disk from shop delay white рычажок, — put forward from a reception nest of shop a disk take manually.
Try not to touch with fingers a working surface of a disk!
Application of the transitive adapter for 8-centimetric disks can lead to a system exit out of operation!
Activation of reproduction of laser records
