Remote control effective range
Refer to the illustration about the location of the Infra-
Red (IR) remote control sensor(s). The remote control
must be held at an angle within 30 degrees perpendicular
to the projector's IR remote control sensor(s) to function
correctly. The distance between the remote control and
the sensor(s) should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote
control and the IR sensor(s) on the projector that might
obstruct the infra-red beam.
Replacing the remote control batteries
1.
To open the battery cover, turn the remote control over to view its back, press on the
finger grip on the cover and slide it down in the direction of the arrow as illustrated.
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 pushing it back down into position.
Stop when it clicks into place.
WARNING
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 drained 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.
