Effective range
Infra-Red (IR) remote control sensor is located on top of the projector. Ensure to hold the remote control at an angle within 30° (horizontally) or 20° (vertically) perpendicular to the projector’s IR remote control sensor to function correctly. The distance between the remote control and the sensor should not be longer than 7 meters (~22 feet).
Note: When pointing the remote control directly (0 degrees angle) on the IR sensor, the distance between the
remote control and the sensor should not be longer than 10 meters (~32 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.
Make sure the IR transmitter of the remote control is not being shined by sunlight or uorescent lamps
directly.
Please keep the remote controller away from uorescent lamps for over 2 meters or the remote
controller might become malfunction.
If the remote control is close to Inverter-Type uorescent lamps, it might become ineffective from time
to time.
If the remote control and the projector are within a very short distance, the remote control might
become ineffective.
When you aim at the screen, the effective distance is less than 7 meters from the remote control to the
