Remote Control Battery Installation
To insure safe operation, please observe the following precautions:
● Use (2) AA or LR6 type alkaline batteries.
● Always replace the batteries in sets.
● Do not use a new battery with a used battery.
● Avoid contact with water or liquid.
● Do not expose the remote control to moisture, or heat.
● Do not drop the remote control.
● If a battery has leaked on remote control, carefully wipe case clean and install new batteries.
● Risk of explosion if battery is replaced by an incorrect type.
● Dispose of used batteries according to the instructions.

Preparation
Caution about Radio Wave
The remote control operates in 2.4 GHz band, the same frequency band used for industrial, scientific, and medical
equipment (such as pacemaker), as well as amateur radio stations.
Before operating the remote control, make sure no electromagnetic interference occurs and pay attention to the
following cautions.
1. Be sure that there are no other devices in the area that may use the same frequency band as the remote
control.
2. If any other devices are causing radio interferences, change the communication frequency channel or
move to other location.
Caution in Wireless LAN Interference
Under wireless LAN environment based on IEEE 802.11b and IEEE802.11g, the remote control may not operate
properly due to radio interferences. The remote control is initially set to use 2.472 GHz band (CH1) corresponding
to several channels of wireless LAN.
Should the remote control not operate properly due to radio interference, switch the communication frequency
channel to CH2. Yet the operating condition is not improved, try CH3 and CH4. In case of failure in every channel
operation, relocate other radio equipment using 2.4 GHz band away from the remote control and the projector.
