When the batteries are inserted for the first time,
or the batteries are replaced, all the indications

If this happens, remove the back cover of the

nal, and by shorting it with a minus screwdriver,
it will return to normal.

mission code
When two indoor units are installed in the same
room, in order to prevent operating errors caused

The unit is set to A when it is shipped.
By adding a jumper wire to the remote control side and shorting the Jx at the indoor printed circuit board,
