SETUP AND INSTALLATION
Effective range
Infra-Red (IR) remote control sensor is located on the top side of the projector. Make sure the operating angle
of the remote control is pointed within ²35° to the IR receiver on the projector. The distance between the remote
control and the sensor should not be longer than 6 meters at operating angle 45° and 14 meters at operating angle
0°.
±
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 closed 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 5 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.
