CENTRAL REMOTE CONTROLLER TROUBLESHOOTING
Printed circuit
board error
(Control panel)
1. Error occurence condition
Error occurs at control
panel printed circuit board
and central remote controller
cannot be operated.
2. Relevant operation
Error display.Only error code
display is operated.
Other operations are
ineffective.
3. Clearance 
Error is cleared and central
remote controller bcomes
operable again.
2. Conrol panel printed circuit
board is faulty.
1. After ACL key is pressed, or power
is turned on again:
1) If error dosen't occur, printed circuit
board is normal. Then, remove
noise sources near operation panel.
2) If error occurs again, remove noise
sources and take measure with
the following countermeasure No.2.
1. Error occurence condition
