Notes on remote controller operation
• Some environment factor may hamper the operation of remote controller. If so, point remote 
controller at the projector and repeat the operation again.
•  In case the effective range of the remote controller is shortened or the remote controller stops 
functioning, please replace the battery with a new one.
•  The projector enters wired control mode automatically and cannot be controlled by the 
remote controller’s IR signal, once the cable terminal of a remote controller is inserted in 
the projector’s wired control port. To control the projector with the IR signal of the remote 
controller again, remove the wire control terminal from the projector.
•  IR signal may be interrupted and rendered useless when the remote controller is exposed to 
bright sunlight or fluorescent light. Make sure the installation environment is proper for IR 
remote controller.
Remote control operation
• Make  sure  that  there  is  nothing  positioned  between  the  remote  control  and  the  infrared  (IR) 
sensors on the projector that might obstruct the IR beam from the remote control reaching the 
projector.
•  The effective range of the remote control is up to 7 meters, and at an angle within 30 degrees 
of the IR beam. Always aim straight at the projector, however most screens will also reflect the 
IR beam to the projector.
Caution:
DO NOT expose your remote controller to high temperatures or moisture or it may function abnormally.
