Electronic Antitheft System, Deactivating
Reactivating a locked radio is only possible by entering correct code number for electronic antitheft system.
Code number for electronic antitheft system is listed along with radio serial number on radio card. Refer to the operating instructions.
For reasons of safety, radio card should not be stored in the vehicle. Obtain the code number from the customer, if necessary.
If a radio unit is replaced, code number of replacement unit must also be used.
Inform the customer that the code number has changed.
-- Obtain code number for the unit.
-- Switch on radio unit.
Radio displays "SAFE" and then "1000". No operating of buttons is required for this.
-- Using station buttons -1- to -4-, enter code number affixed to radio card. First digit of code number is entered with button 1, second with button 2, etc.
-- Then press Stations button located beneath "OK" on display (is normally last station button) and hold firmly until anti-theft coding is activated. This is indicated by a short signal sound.
If the code number has been entered correctly into radio unit, a radio frequency appears on the display.
If the antitheft code has been entered incorrectly, it can be corrected immediately in another attempt. If antitheft code is entered incorrectly twice, then the radio unit is locked for an hour. Then leave the radio unit and the ignition switched on. After one hour, then the procedure for deactivating the electronic antitheft system can be repeated. Keep in mind: Always two attempts to input code, after that the radio unit is locked for one hour.
