pg. 130 Anti -theft code - HU-415 and HU-615
Anti-theft code
The radio features anti-theft circuitry. If the set is removed from the vehicle or if the battery power is disconnected, a
special code must be entered to enable operation of the set.
Your Volvo retailer will supply you with this code.
NOTE: Volvo recommends that you store the radio code in a safe place.
A red LED will flash when the key had been removed from the ignition to confirm that the anti-theft circuitry has
been activated.
To enter the code
After installation or when the set has been disconnected from power, the set displays "input CODE ****" when it is
switched on.
Enter the 4-digit code using the 1-20/DISC knob. Select a number for a digit by rotating the 1-20/DISC knob. And
then push the knob to enter the number. Repeat the procedure for all 4 digits.
If the correct code is entered the set is ready to use.
If you enter an incorrect code you must enter the correct code again from the beginning.
