Introduction
Battery Installation
Remote Control Precautions
• Handle the remote control carefully.
• If the remote control gets wet, wipe it dry immediately.
• Avoid excessive heat and humidity.
• Do not place the battery upside down.
1. Press firmly and slide the battery cover off.
2. Install new batteries (AAA).
Ensure that you have the
batteries’ polarity (+/–)
aligned correctly.
3. Slip the cover back over the
batteries until it snaps into
place. Do not mix different
types of batteries or new and
old batteries.
CAUTION:
Danger of explosion if battery is incorrectly replaced.
Replace only with the same or equivalent type recommended by the manu-
facturer.
Dispose of used batteries according to your local regulations.
The infrared signal
operates by line-of-
sight up to a distance
of about 22 feet/7 m
and within a 60-degree
angle of the remote
sensor on the projector
cabinet.
The projector will
not respond if there
are objects between
the remote control
and the sensor, or if
strong light falls on the
sensor. Weak batteries
will also prevent the
remote control from
properly operating the
projector.
