Remote control effective range
Infra-Red (IR) remote control sensor is located on the front and the rear 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 7 meters (~ 23 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
• 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.
