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

 

8 meters (~ 26 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.

Please follow the illustrated instructions. Push and hold 
the locking arm while pulling 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 excessive heat and humidity. 

•

There may be battery damage if the battery is 
incorrectly replaced. 

•

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

•

Dispose of the used battery according to the battery 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.
