How to resume normal operation (ESN security lock out)
If power is disconnected while ESN security is active (a Key CD was programmed), operation is disabled until power is restored and the unit unlocked. Follow this procedure to resume normal operation.
1When 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 CD3424 is ready to accept your Key CD into the slot.
2Insert your Key CD into the slot.
If the correct CD is inserted, an [OK] message will appear for two seconds and the CD will begin playing.
•If an incorrect CD is inserted, an [ERR_] ("ERR" and error
ATTENTION number) message will appear for two seconds, after which the CD will be ejected.
•If [ERR5] (the 5th time an error has occurred) appears, [HELP] will appear, after which the CD will be ejected. When [HELP] appears, carry out the operations for an ESN security lock out by following the procedure in "What happens if an incorrect CD is inserted?" (See next page).
•You must use the same CD used for Key CD programming; a duplicate CD may not work properly.
