When the remote control unit is used with the
aforementioned interference-prevention setting,
a minimum distance guaranteeing the
prevention of unintended unit responses is 5m.
Please operate remote control unit switches with the unit faced correctly
toward the indoor unit's receiver section.
Effective operation distance can vary with the luminance around the
receiver and the reflection from walls of the room.
When the receiver is exposed to intensive light such as from the direct
sun or a strong light, it may become operable only from a short distance
or unable to receive signals at all.
