Electronic Anti-Theft Protection
The Radio -R- is equipped with convenience anti-theft protection, which operates in conjunction with the instrument cluster. The radio code is stored internally inside the Radio -R- and inside the instrument cluster.
After disconnecting the power supply to the Radio -R-, it is ready for use and the radio code does not need to be entered again. The requirement is that the anti-theft system has been activated for the first time and that the Radio -R- is reconnected in the same vehicle.
Use the Vehicle Diagnostic Tester to get the radio code. The radio card and the label on the Radio -R- that were used in the past are no longer used.
The Vehicle Diagnostic Tester must be "online" to retrieve the radio code and the user must be authorized to access radio codes.
Electronic Anti-Theft Protection, Deactivating:
-- Connect the Vehicle Diagnostic Tester.
-- Select Guided Fault Finding .
-- Use the GO TO button to select the "function/component selection" and the following menu options one after the other:
- Body
- Electrical Equipment
- 01 - On Board Diagnostic (OBD) capable systems
- Sound System
- Sound System functions
- Radio code inquiry
Authorization will be requested from the system: Then the operating data, the VIN and the Radio -R- serial number will be automatically read out.
The radio code for the electronic anti-theft system is attached to the radio card next to the serial number.
For reasons of safety, do not leave the radio card in the vehicle. Get the radio code from the customer.
If a Radio -R- is being replaced, then use the radio code of the replacement radio.
Tell the customer the radio code has been changed.
-- Get the radio code.
-- Switch on the Radio -R-.
The Radio -R- automatically displays "SAFE" and then "1000".
-- Enter the radio code using the radio station buttons 1 through 4. Use the first radio station button to enter the first digit of the radio code. Use the second radio station button to enter the second digit.
-- Press the arrow and hold it until the electronic anti-theft protection is activated. This is indicated by a short signal sound.
If the radio code has been entered correctly into Radio -R-, a radio frequency appears on the display.
It is possible to enter the radio code again if it was entered incorrectly. If radio code is entered incorrectly twice, then the Radio -R- will lock up for one hour. Leave the Radio -R- on and the key in the ignition lock. The process can be repeated again after an hour. Note: Always two attempts, after that the Radio -R- will lock up for one hour.
