SETUP AND INSTALLATION
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 degrees perpendicular to the projector’s top IR remote control sensor to function correctly. The
distance between the remote control and the sensor should not be longer than 6 meters (~ 20 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 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.
±
Make sure the IR transmitter of the remote control is not being shined by sunlight or fluorescent lamps
directly.
±
Please keep the remote controller away from fluorescent lamps for over 2 meters or the remote
controller might become malfunction.
±
If the remote control is close to Inverter-Type fluorescent 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 6 meters from the remote control to the
screen and reflecting the IR beams back to the projector. However, the effective range might change
according to screens.
