4.5 Custom cord switching procedure
If two wireless remote controls are installed in one room, in order to prevent wrong operation due to mixed signals, please modify the
printed circuit board in the indoor unit’s control box and the remote control using the following procedure. Be sure to modify both
boards. If only one board is modified, receiving (and operation) cannot be done.
(1) Modifying the indoor unit’s printed circuit board
Take out the printed circuit board from the control box and cut off jumper wire (SKM20~50 model: J13 SKM60·71, STM, SRRM
model: J4) using wire cutters.
After cutting of the jumper wire, take measures to prevent contact with the other the lead wires, etc.
