TROUBLESHOOTING
Problem
Power does not turn on.
(No sound is produced.)
Cause
Fuse is blown.
Incorrect wiring.
Measure
Replace with a fuse of the same amperage as the old fuse.
Read the attached "Installation/Wire connection Guide" once ange
and wire properly.
No sound output when
operating the unit with
amplifiers or power
antenna attached.
Power antenna lead is shorted
to ground or excessive current
is required for remote-on the

1. Turn the unit off.
2. Remove all wires attached to the power antenna lead. Check
each wire for a possible short to ground using an ohm meter.
3.Turn the unit back on.
4. Reconnect each amplifier remote wire to the power antenna lead
one by one. If the amplifiers turn off before all wires are attached,
use an external relay to provide remote-on voltage
(excessive current required).

About the 2-ZONE function
The 2-ZONE function is a function that outputs separate sounds fr-
om the MAIN zone and SUB zone by simultaneously operating two
sources in the one center unit, thereby allowing plural listeners to
enjoy separate music sources.
This unit can control its internal sources(radio, CD, MP3, etc.) to play
back them, and further, can simultaneously play back sources from
external equipment connected via CeNET (for instance, CD chang-
ers etc.).
The sources of the MAIN zone are played back from the speakers
of the vehicle side, and those of the SUB zone are from the
headphone systems.
General
CD/MP3/WMA
Notes:
* Except AUX, the MAIN and SUB zone cannot simultaneously use sources
inside this unit.
Also, external equipment connected via CeNET cannot simultaneously be
used.
* The TV mode while the 2-ZONE function is tuned on is forced to change to
"VTR playback."
* The ISR function cannot be operated when the 2-ZONE function is turned on.
* The Audio mode and ADF function cannot be set for the sources of the SUB
zone.
* If any of following external equipment is connected, this function is disena-
bled.
5.1 channel surround decoder.
