bled. (See the diagram at right)

(4) Custom cord switching procedure

If two wireless remote control are installed in one room, in order to prevent wrong
operation due to mixed signals, please modify the printed circuit board in the in-
door 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.
(a) Modifying the indoor unit's printed circuit board
Take out the printed circuit board from the control box and cut off jumper
wire (J00) using wire cutters.
After cutting of the jumper wire, take measures to prevent contact with the
other the lead wires, etc.
(b) Modifying the wireless remote control
