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).

6 M

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 or replacing the remote control battery

1. Pull out the battery holder.

2. Insert the new battery in the holder. Note that the positive polarity should face outward.

3. Push the holder into the remote control.

• Avoid excessive heat and humidity.

•There may be danger of damage to the remote and injury to those nearby if the battery is incorrectly replaced.

•Replace only with the same or equivalent type recommended by the manufacturer.

•Dispose of the used battery according to the manufacturer’s instructions.

•Never throw a 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 a long time, remove the battery to prevent damage to the remote control from possible battery leakage.
