Note
f When operating the remote control by directly pointing at the remote control signal receiver of the projector, operate the remote control
within a distance approximately 30 m (98'5") from the remote control signal receiver. The remote control can control at angles of up to ±30°
vertically and horizontally, but the effective control range may be reduced.
f If there are any obstacles between the remote control and the remote control signal receiver, the remote control may not operate properly.
f The signal will be reflected off the screen. However, the operating range may be limited from light reflection loss due to the screen material.
f If the remote control signal receiver directly receives strong light, such as fluorescent light, the remote control may not operate properly. Use
it in a place distant from the light source.
f The power indicator <ON (G)/STANDBY (R)> will blink if the projector receives a remote control signal.
