Electronic anti-theft system
The radio has a comfortable electronic anti-theft system that works in conjunction with the instrument cluster. When connecting the radio after turning off the power, it works without entering the security code. Prerequisites: the first activation of the electronic anti-theft protection system has been carried out, the radio is installed in the same car.
Deactivating the electronic anti-theft system
Re-commissioning of a previously blocked radio is only possible after entering the correct code for the electronic anti-theft protection system.
Instructions: The code for the electronic anti-theft protection system is located on a sticker along with the radio number on the radio card. For safety reasons, do not store the radio card in the vehicle. If necessary, request the code from the customer. If the radio is replaced, the code for the new radio must be used. Inform the client of the new code. Find out the radio code. Turn on the radio. The radio will display SAFE followed by: 1000. No buttons need to be pressed to enter this mode. The position of the entered code is shown on the display next to the four multifunction keys in the form of _X_ characters. Using the four multi-function keys, enter the code indicated on the radio card sticker in the correct sequence. By repeatedly pressing the corresponding keys in turn, achieve the display of the code in the center of the display. Confirm your entry by pressing the softkey next to the word ENTER. After that, the radio will be ready for operation again, and will work in the same mode as before switching off.
Instructions: If an incorrect number was entered when unlocking, the display will again show the flashing message SAFE and then 1000. Now you can repeat the process again. The attempt number is shown on the display. If you enter the code incorrectly again, the device will be blocked for about an hour, i.e. during this period of time, it cannot be unlocked. The display will show the message SAFE. After an hour (radio and ignition must remain on) the indication of unlock attempts on the display will disappear, and the electronic lock can be unlocked as described above. Operation of the device in a cycle of two failed attempts, the hourly blocking continues further.
