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.
Incorrect code
