Deactivating electronic anti-theft system
A blocked radio unit can only be returned to normal operation by entering the correct code number for the electronic anti-theft system.
  Note
t  The code number for the electronic anti-theft system along with the unit number are stuck on the radio card → Operating manual.
t  The radio card should not be kept in the vehicle for security reasons. If necessary, ask the customer for the code number.
t  If a radio unit is renewed, the code number of the replacement radio must be used.
t  The customer must be informed that the code number has changed.
–  Obtain code number for unit.
–  Switch radio unit on.
The unit automatically displays “SAFE” and then “1000”. There is no need to operate any buttons.
–  Use station buttons 1 to 4 to enter the code number stuck onto the radio card. Use the first key to enter the first code number, the second key to enter the second code number and so on.
–  Then actuate the right rotary push-button on the radio unit and hold this down for 2 seconds. The radio unit is then ready to operate again and switches to its last operating state.
  Note
If an incorrect code number has been entered on deactivating the electronic lock, “SAFE” first flashes in the display, followed by “1000” again. The entire process can now be repeated again. The number of attempts is shown in the display. If an incorrect code number is entered again, the unit is blocked for approx. one hour, i.e. it cannot be operated. This lock is indicated by “SAFE” and a small “2” being continuously shown on the left of the display. After one hour - the unit must remain switched on - the attempt display is extinguished and the electronic lock can be deactivated as described above. The “two attempts, blocked for one hour” cycle still applies.
