When aiming the remote control toward the sensor on this unit (front or rear), ensure that the distance to the sensor is within 7 m (23 ft).
If the remote control fails to work properly, move closer to this unit.
Control through reflection off a screen, etc.
Ensure that the total of distance A (between this unit and the screen) and distance B (between the remote control and the screen) is within 7 m (23 ft).
As the efficiency of signals reflected from the remote control unit varies with the type of screen used, the operable distance may decrease.
