About ESN
This deck incorporates ESN (ECLIPSE Security Network). The ESN is
a security system which disables all deck functions when the power
is restored if the deck is stolen from the vehicle. Once the ESN is
activated, removing power to the desk or vehicle will activate the
security feature.
Setting or canceling of the security feature can be done with a "Key
CD". It is necessary to register a music CD as the "Key CD" in
advance.
