unit unlocked. Follow this procedure to resume normal operation.
When the power is turned on after disconnecting the
battery power, a [SEC] message will appear for two
seconds. Thereafter, the message changes to [DISC]
and the CD3403 is ready to accept your Key CD into the
slot.

Insert your Key CD.

If the correct CD is inserted, an [OK] message will appear for
two seconds and the CD will begin playing.
ATTENTION
•If an incorrect CD is inserted, an [ERR] message will appear
for two seconds, after which the CD will be ejected.
•You must use the same CD used for Key CD programming;
a duplicate CD may not work properly.
