Operating range
If the remote control unit is held so
that it is facing directly in front of the
remote control signal receptors on
the front or rear of the projector, the
operating range is within
approximately 7 m (23´) from the
surfaces of the receptors.
Furthermore, the remote control unit
can be operated from an angle of
±30° to the left or right and ±15°
above or below the receptors.
