Operating the remote control
Note
1. This remote controller use 2 x R03/AAA batteries.
2. When you first operate M400, press the C key first.
Remote control
Install 2 x AAA batteries as instructions.
When using the remote control, point it toward the remote con-trol 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.
