Problem
Cause
Remedy
The unit cannot be operated using the remote
control.
The unit is out of the operating range.
Use the remote control within the operating range (p. 3).
The batteries are weak.
Replace with new batteries (p. 3).
The remote control sensor of the unit is exposed to direct sunlight or
strong lighting.
Adjust the lighting angle, or reposition the unit.
The TV cannot be operated when the TV’s
remote control is pointed toward the unit’s
remote sensor.
The unit and TV are too far apart (or too close), preventing proper
operation of the unit's TV remote repeater function.
Position the unit so that it is more than 5 cm (2 in) away from the TV (p. 10).
There are obstacles between the unit and the TV (cables, etc.),
preventing proper operation of the unit's TV remote repeater function.
Remove obstacles between the unit and the TV.
The TV’s remote control does not use infrared signals.
The unit’s TV remote repeater function cannot be used. Reposition the unit so
that it does not obstruct the remote control sensor on the TV, and point the
TV’s remote control at the remote control sensor on the TV to control the TV.
Signals transmitted from the TV’s remote control and the unit's TV
remote repeater interfere with each other, making it difficult for the TV
to receive signals.
