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° perpendicular to the projector’s IR remote control sensors to function correctly. The distance
between the remote control and the sensor should not be longer than 7 meters (~22 feet).
Notee: 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 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 7 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.
