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 of 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.
Replacing the remote control battery
1. Pull out the battery holder.
2. Insert the new battery in the holder. Note
the positive polarity should face outward.
3. Push the holder into the remote control.
Avoid leaving the remote control and
battery 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 battery according to the manufacturer’s instructions.
Never throw the battery into a fire. There may be danger of an explosion.
If the battery is dead or if you will not be using the remote control for an extended period
of time, remove the battery to avoid damage to the remote control from possible battery
leakage.
