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.
1 .
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 CD8051 is ready to accept your Key
CD into the slot.
2 .
Insert your Key CD.
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] 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.
