Remote control

●Install 2 x AAA batteries as instructions.
●When using the remote control, point it toward the remote control signal receiver on the main unit from a distance of 5 m (16 ft) or less. Do not place obstructions between the main unit and the remote control.
●The remote control might not work if the remote control signal receiver on the unit is exposed to direct sunlight or bright light. If this occurs, try moving the unit.Beware that use of this remote control could cause the unin-tentional operation of other devices that can be controlled by infra.

Note
1. This remote controller use 2 x R03/AAA batteries.
2. When you first operate SH-9, press the B key first.
