Keys for search of radio stations (fig. 1-63).

Fig. 1-63. Arrangement of keys of search of radio stations (1), handles of inclusion and volume control (2)


Pressing one of keys for search of radio stations carries out automatic search of radio stations in the necessary direction.

For manual search of radio stations press both keys during more than 2 pages. On the display MAN symbol appears. Now when pressing the top or lower key step-by-step search of radio stations in the necessary direction is carried out.
By pressing and long deduction of a key the speed of step-by-step search of radio stations increases.
Through 10 from later end of search of radio stations the receiver automatically switches to the normal mode of search of radio stations.

Handle of inclusion and volume control (fig. 1-63). The radio receiver joins and switched off by the volume control handle.
If on the car the automatic antenna is installed, then at turning on of the radio receiver it starts.
If the key is taken from the ignition lock, the radio receiver is automatically switched off, at inclusion of ignition – again turns on.
At the switched-off ignition it is possible to turn on the radio receiver, turning the handle of loudness 2. Time of its work of-1 h. After this time the radio receiver is automatically switched off. After repeated inclusion the radio receiver works again during 1 h.
Loudness smoothly changes turn of the handle of the regulator of loudness.

Buttons of the fixed settings of stations of the radio receiver (fig. 1-65) and the choice of a compact disk (CD).

Buttons of the fixed settings of stations
Short-term pressing: inclusion of the fixed control for previously chosen radio station.
Long pressing before emergence of a pause in the accepted transfer: storing of a current setting in the manual mode.
On the display the frequency of the working radio station and number at which the radio station is brought in memory is displayed.
It is possible to enter 12 radio stations into memory in FM range (on 6 in two ranges) and 6 radio stations in AM range.

Choice of a compact disk (CD).
• By short-term pressing of the button playing of the corresponding compact disk begins.
Number of the chosen compact disk is highlighted on the display, for example CD 01. If the compact disk is not established, on the display NO CD is highlighted.

Button of inclusion of AM of the range (fig. 1-65). When pressing the button the radio receiver switches to reception of radio stations in the range of average waves. Information on the chosen range is output to the display.

Button of inclusion of FM 1/2 of the range (fig. 1-65). When pressing the button the radio receiver switches to reception of radio stations in the range of very high frequency (FM I or FM II).
Transition from FM I range to the range of FM II is carried out repeated pressing of the button. Information on the chosen range is output to the display.

After pressing of the TP key of the TP and EON function are activated.
If to press the TP button more than 2 about the radio receiver switch to AM range, the TP function is switched off.

Fig. 1-67. Arrangement of the RDS (9) button



Radio Data System (fig. 1-67).
The radio receiver can accept signals of system of radio data of RDS. If the signal to the chosen radio station in the range of FM satisfies to the RDS standard, the receiver is automatically adjusted on that frequency which provides the best quality of reception.
The RDS button has 2 functions.
Pressing of the button RDS joins.
Pressing of the button regional radio stations REG ON and according to REG OFF join.

RDS
At turning on of the receiver or search of radio stations automatically there is a search of RDS radio stations. At the same time the symbol of RDS is highlighted on the display.
At reception of the radio station working in the RDS mode on the display the name of the station, for example BAYERN 3 is highlighted.
At trips on a long distance and adverse conditions of reception it was necessary to reconstruct the radio receiver. RDS automatically from the list of alternative frequencies will find most the best and will include it. This process happens silently.
At the included RDS also radio stations which do not transfer the RDS program now can be accepted. Therefore it is recommended that this radio station was whenever possible constantly included.

Regional radio stations
The REG function joins pressing of the RDS button of not less than 2 pages. As confirmation on the display the inscription REG OFF appears at this time.
If once again to press not less the RDS button than on 2 with on the display the inscription REG ON will appear.
Example. The program 2 Bavarian radio transfers the notice of BR 2 MUN, either BR 2 SH, or BR 2 OVV with regional programs of various contents to certain time.
At reception of these regional programs on the display the inscription REG appears.
Whenever possible the REG function has to be included constantly.
At the movement in the area in which action of several regional radio stations is blocked and the radio receiver accepts REG radio stations worse and worse, function of reception of regional radio stations has to be switched off.
At record in memory of RDS radio stations it is necessary to press the corresponding button stations only when the name of radio station appears on the display.
EON (information of Concerning Other Networks)
EON is the RDS function which provides reception with the automobile radio receiver of all messages of radio station in the TP mode.
Irrespective of the program installed at present all TP messages of other radio stations have to be heard.
Messages on accidents have advantage before all other functions.

Notices of the display.
All information is output to the display: RDS frequency, the name of radio station, the number of stations in FM I and FM II; in compact disk play mode – CD 01 … CD 06, and in case of their absence – CD NO.

The coded device against theft. The device is executed on the basis of the microprocessor. After disconnection of the radio receiver from electric network of the car (removal of the rechargeable battery, dismantle of the radio receiver or its initial installation) it is necessary to enter a safety code. The radio receiver can be turned on only after input of the correct code.
After turning on of the radio receiver on the display the inscription SAVE is highlighted – it is possible to enter a code against theft.

Introduction of a code
Number of a code is pasted on the operation manual on the radio receiver.
For introduction of the correct code it is necessary to perform the following operations.
– Turn on the radio receiver – on the display the inscription SAVE is highlighted.
– At the same time press the FM and DX buttons and hold them before emergence of indication "1000". Release buttons. Do not press the FM and DX button again at all, otherwise number 1000 will be accepted to a code.
– By means of buttons 1-4 (the fixed settings) enter number of a code: the first figure of a code is entered by the button the 1, second figure – the button 2, etc. Buttons 5 and 6 are not used.
– At the same time press the FM and DX buttons and hold them before emergence of indication of SAVE.
– Release buttons.
Now the radio receiver is ready to work.
If at input of a code the mistake was made, then on the display there will be an indication of SAVE in the blinking mode which then is highlighted constantly.
Repeat attempt of installation of a code. The number of attempts is reflected in the display.
If the incorrect code is entered repeatedly, the receiver will be blocked on 1 h.
In 1 h it is possible to repeat two attempts to establish a code. If they are not successful, the receiver will be blocked on 1 h.
