OPERATING TIPS
AUTO Restart
In Event of Power Interruption
●The air conditioner power has been interrupted by a power failure. The air conditioner will then restart auto- matically in its previous mode when the power is restored.
●Operated by setting before the power failure.
●If a power failure occurs during TIMER operation, the timer will be reset and the unit will begin (or stop) operation at the new time setting. In the event that this kind of timer fault occurs the TIMER Indicator Lamp will flash (see Page. 3).
●Use of other electrical appliances (electric shaver, etc.) or nearby use of a wireless radio transmitter may cause the air conditioner to malfunction. In this event, temporarily disconnect the Power Supply Plug, reconnect it, and then use the Remote Control Unit to resume operation.
