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.

If an  incorrect code has been entered  "Error" is displayed. Enter the correct code. After three unsuccessful coding
attempts the set will lock and  remain locked for two hours.

During this waiting period:
 the battery must  be  connected
 the ignition key  must  be  turned to position I
the unit must  be  turned on
Make sure the headlights are turned off to help prevent battery drain.
Enter the code again once 2 hours have elapsed.
