Effective Range of Remote Control Unit
■
When directing the remote control toward this
unit.
●
When aiming the remote control towards the
remote sensor on this unit, ensure that the
distance to the sensor in front or at the rear of
this unit is within 7 m.
●
If the remote control fails to work properly, move
closer to this unit.
■
When reecting off a screen
●
Ensure that the total of distance A between this
unit and screen and distance B between remote
control and screen is within 7 m.
●
As the efciency of signals reected from the
remote control unit differ with the type of screen
used, operable distance may decrease.
