Remote Control Operation
The infrared emitter is at the top of the remote control next to the
laser pointer. The infrared emitter has a range of about 3m (about
10 feet) at an angle of about 20° from the center of the sensors
(both front and back).
Do not block the infrared emitter. If the projector does not pick up
the signals from the remote control, make sure the emitter and
sensors on the projector are not blocked and that the emitter is
within range.
You can operate the remote control when pointed at either the front
or the back of the projector.
Notes about the remote control:
• The remote control may not operate in strong sunlight or
when other strong lights, such as fluorescent lighting, are
shining on the sensors.
• The remote control may not operate well in unusual areas
or in particular locations or surroundings. If that occurs,
change the direction of the remote control with respect to
the projector.
• Do not drop, jolt, or disassemble the remote control.
• Do not get the remote control wet, or place wet objects on
it.
• Keep the remote control out of locations with excessively
high temperature or humidity.
