16 Introduction
Remote control effective range
Infra-Red (IR) remote control sensors are
located on the front and the back of the
projector. The remote control must be held at
an angle within 30 degrees perpendicular to
the projector's IR remote control sensors to
function correctly. The distance between the
remote control and the sensors should not
exceed 6 meters (~ 20 feet).
Make sure that there are no obstacles between
the remote control and the IR sensors on the
projector that might obstruct the infra-red
beam.

Installing remote control batteries
1. To open the battery cover, turn the remote
control over to view its back, push on the
finger grip on the cover and slide it up in the
direction of the arrow as illustrated. The
cover will slide off.
2. Remove any existing batteries (if necessary)
and install two AAA batteries observing the
battery polarities as indicated in the base of
the battery compartment. Positive (+) goes to
positive and negative (-) goes to negative.
3. Refit the cover by aligning it with the base
and sliding it back down into position. Stop
when it clicks into place.
Avoid leaving the remote control and batteries
in an excessive heat or humid environment like
the kitchen, bathroom, sauna, sunroom or in a
closed car.
Replace only with the same or equivalent type
recommended by the battery manufacturer.
Dispose of the used batteries according to the
manufacturer's instructions and local
environment regulations for your region.
Never throw the batteries into a fire. There may
be danger of an explosion.
If the batteries are dead or if you will not be
using the remote control for an extended
period of time, remove the batteries to avoid
damage to the remote control from possible
battery leakage.
