12.3. REMOTE CONTROL
12.3.1. 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 happens, remove the back 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.
12.3.2. 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, set up
the remote control [B
←→ A] switch (SW1).
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, it is possible to select 4
types of transmission codes including one at time of delivery condition (1).

The batteries can be used for one year approximately. When the
batteries become close to 2.6V, the battery mark
flashes. Replace
the batteries immediately. Otherwise, the remote control display will not
appear.
