Operating Range for Wireless Remote Control

NOTE: Actual operating range may differ slightly
from that shown in the drawing.
TIP: You can determine which remote sensor on
the projector is enabled in wireless mode. The op-
tions are: front, rear or both. (→ page 113)
• The infrared signal operates by line-of-
sight up to a distance of about 22 feet/7 m
and within a 60-degree angle of the remote
sensor on the projector cabinet.
• The projector will not respond if there are
objects between the remote control and
the sensor, or if strong light falls on the
sensor.
Weak batteries will also prevent the remote
control from properly operating the projec-
tor.

Remote Control Precautions

• Handle the remote control carefully.
• If the remote control gets wet, wipe it dry immediately.
• Avoid excessive heat and humidity.
• Do not heat, take apart, or throw batteries into fire.
• If you will not be using the remote control for a long time, remove the batteries.
• Ensure that you have the batteries' polarity (+/–) aligned correctly.
• Do not use new and old batteries together, or use different types of batteries together.
• Dispose of used batteries according to your local regulations.

that you have the batteries' po-
larity (+/–) aligned correctly.
