Servicing Information
(C) Remote Control Transmission Setting
• 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.
• Changing the wireless remote control transmis-
sion 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.
