Remote control effective range

Infra-Red (IR) remote control sensor is located on the
front of the projector. The remote control must be held at
an angle within 30 degrees perpendicular to the
projector's IR remote control sensor to function correctly.
The distance between the remote control and the sensor
should not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote
control and the IR sensor on the projector that might
obstruct the infra-red beam.

Replacing the remote control battery

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.
