• Remote Control Reset
When the batteries are inserted for the first time, or the
batteries are replaced, all the indications will blink and the
remote control might not work.
If this happen, remove the cover of the remote control and
you will find a resetting terminal, and by shorting it with a
minus screwdriver, it will return to normal.
• Changing the wireless remote control transmission
code
When two indoor units are installed in the same room, in
order to prevent operating errors caused by using two
remote controls, cut a jumper wire at the remote control
printed circuit board (J - A) and cut a jumper wire at the
indoor printed circuit board (JX4). It is possible to select
from 4 types of transmission codes including one at time of
delivery condition (0).
