REMOTE CONTROLLERS OPERATION
9.1 WIRELESS REMOTE CONTROL FUNCTION
PRECAUTIONS:
x This controls the operation of indoor unit. The range of control is 7 meters. If indoor lighting is controlled electronically, the
range of control may be shorter, in some cases; the control signal may not be received. This unit can be fixed on a wall
using the fixture provided. Before fixing it, make sure the indoor unit can be controlled from the remote controller.
x Press buttons only with fingers. Do not press buttons by any other item, as it may damage the buttons.
x Do not put the remote controller in the following places.
o In direct sunlight.
o In the vicinity of a heater.
x Handle the remote controller with care. Dropping it or getting it wet may compromise its signal transmission capability.
x After new batteries are inserted into the remote controller, the unit will initially require approximately 10 seconds responding
to commands and operating.
x Once the outdoor unit stops, it will not restart for about 3 minutes (unless we switch OFF and ON the power or unplug and
plug back the power cord again.) This is to protect the device and does not indicate a failure.
x If you press the FUNCTION selector button during operation, the device may stop for about 3 minutes for protection.
