"CD player"R89„MP3“ - anti-theft system
"CD player" -R89-„MP3“ - anti-theft system
The "CD player" -R89-„MP3“ is equipped with an electronic anti-theft system.
After the electronic anti-theft system is activated for the first time, an internal code is saved in the "CD player" -R89-„MP3“ and in the Combined instrument -K- of the vehicle. If during repair work the "CD player" -R89-„MP3“ should experience a power outage (for example when removing the "CD player" -R89-„MP3“ or the battery), a data exchange occurs between the "CD player" -R89-„MP3“ and the Combined instrument -K- after the voltage supply is restored.
In this manner, a comparison is made between the internal code of the "CD player" -R89-„MP3“ and the Combined instrument -K-. If the code is identical, the Combined instrument -K- recognizes that the "CD player" -R89-„ MP3 “ installed belongs to the vehicle, and the radio becomes operational without the need for entering the anti-theft code.
  Note
t  Each "CD player" -R89-„MP3“ has its own code.
t  The anti-theft system code is on the "CD player" -R89-„MP3“ card along with the equipment ID number → Radio Instruction Manual.
t  For safety reasons, the "CD player" -R89-„MP3“ card should not be kept inside the vehicle. If necessary, request the code from the client.
t  If a "CD player" -R89-„MP3“ is replaced, the replacement equipment code must be used.
t  The customer must be informed that the code number was changed.
The electronic anti-theft system starts operating and blocks the radio whenever:
t  the "CD player" -R89-„MP3“ is removed from the vehicle.
t  the Combined instrument -K- is replaced.
t  the Battery -A- is disconnected.
