operation can be performed.
3. Clearance
Storing (automatic
allocation, manual storing 1,
manual storing 2) is
performed from key
operation, or initial setting
menu mode is cancelled.
1. Perform allocation again.
After manual storing 2 setting:

board is normal.Then, remove noise
sources near indoor unit. If error
occurs again, remove noise sources
and take measure with the following
countermeasure 1-2.
1-2. After ACL key is pressed, or power
is turned on again:
1) If error doesn't occur, printed circuit
board is normal. Then, remove noise
sources near control panel. If error
occurs again, remove noise sources
and take measure with the following
countermeasure No.2-6.
