 When using the wireless remote controller, point it towards the receiver on the indoor unit.  If the remote controller is operated within approximately two minutes after power is

supplied to the indoor unit, the indoor unit may beep twice as the unit is performing the initial automatic check.

 The indoor unit beeps to confirm that the signal transmitted from the remote controller has

been received. Signals can be received up to approximately 7 meters in a direct line from the indoor unit in an area 45° to the left and right of the unit. However, illumination such as fluorescent lights and strong light can affect the ability of the indoor unit to receive signals.

 If the operation lamp near the receiver on the indoor unit is flashing, the unit needs to be

inspected. Consult your dealer for service.

 Handle the remote controller carefully! Do not drop the remote controller or subject it to

strong shocks. In addition, do not get the remote controller wet or leave it in a location with high humidity.

 To avoid misplacing the remote controller, install the holder included with the remote

controller on a wall and be sure to always place the remote controller in the holder after use.
