| Electronic anti-theft lock |
| The radio navigation system is equipped with an electronic anti-theft lock. |
| If the electronic anti-theft lock is activated, the red LED in the top right of the front panel flashes when the unit is switched off and the ignition is off. |
| When the radio navigation system is switched on, the LED goes out and the system is operational. |
| The anti-theft lock is active and locks the system as soon as: |
| t
| the voltage supply (terminal 30) drops below a certain voltage |
| t
| the fuse for the Radio-Navigation System has blown |
| t
| the battery is disconnected before carrying out work on the vehicle |
| Locking of the system by the electronic anti-theft lock is indicated by the “SAFE” text in the display when the unit is switched on. |
| It is only possible to re-start the system by entering the correct code number for the electronic anti-theft lock. |
| –
| Determine code number of unit. |
Note | t
| For safety reasons the radio card with the code number should not be kept in the vehicle. Determine the code number from the customer, if it is not known. |
| t
| Each unit has its own code number. If the Radio-Navigation System is replaced, the code number of the new unit must also be used. The new code number must be handed over to the customer together with the unit documentation. |
| –
| Switch on the radio navigation system. |
| The readout “SAFE” appears in the display. In addition the text “Please enter a numerical code” and the numerical series “0000” appear. |
| –
| Enter the code number indicated on the radio card by marking the digits on the selection field for letters and numbers and confirming. |
| –
| Confirm the code by pressing on the right-hand rotary knob/pushbutton. |
| The unit is enabled and is now operational. |
| If the code number has been correctly entered, the LED located at the top right of the unit must flash when the ignition key is withdrawn. If the LED flashes, the Radio-Navigation System is operational and the electronic anti-theft lock is activated. |
| If an incorrect code number has inadvertently been entered for cancelling the lock, “SAFE” appears in the display, first of all as a flashing readout and then as a constant readout. It is only possible to repeat the procedure for cancelling the electronic anti-theft lock twice. |
| If an incorrect code number is entered once again, the unit is blocked for about 1 hour. |
| It is only possible to carry out a further attempt to cancel the electronic anti-theft lock after this blocking period has elapsed. |
| During the blocking period the unit must remain switched on and the ignition key must be left in the ignition lock. After the blocking period has elapsed, the number of attempts in the display disappears and the electronic anti-theft lock can be cancelled again as described above. |
