Installation procedures
3.5 Using the RCU
Effective range
The Infrared (IR) remote control sensors are located on the front and top sides of the projector. To have the
remote control functions correctly, make sure of the following:
•
The maximum range between the remote control and the sensor is 30 m (98.4 ft).
•
Ensure to hold the remote at the following angles towards one of the IR remote control sensors:
-
horizontally: ±30°
-
vertically: ±20°
•
Make sure there are no obstacles between the remote control and the IR sensors on the projector.
•
Make sure the IR transmitter of the remote control is not directly being shined by sunlight or fluorescent
lamps.
•
Keep a minimum distance of 2 m between the remote control and nearby fluorescent lamps. If not, the
RCU might malfunction.
•
If the projector and remote are within very short distance, the RCU may become ineffective.
•
When you aim at the screen, the effective distance is less than 5 m from the remote control to the screen
and reflecting the IR beams back to the projector. However, the effective range might change depending
on type of screen used.
