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 whilst 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.
