Range of effective remote control signal reception
The diagram below illustrates the range of effective remote control signal reception (Unused new
battery).
40°
12m
12m
40°
Note: Avoid placing the remote control at places of high temperature or humidity as it could cause the remote control
to malfunction.
Installing batteries in the remote control
Remove the cover by sliding
it in the direction indicated
by the arrow.
Insert two new AA
batteries
(observe the polarity).
Replace the cover.
Note1: Be sure to insert the batteries in the corresponding orientations to match the polarities.
Note2: Do not mix new batteries with used batteries as it would shorten the life of new batteries or cause leakage.
Note3: Only used AA batteries as instructed; do not attempt to insert different types of batteries into the remote control.
Note4: If the remote is going to be unused for long periods of time, be sure to remove the batteries to prevent leakage,
which could damage the remote control.
Note5: The liquid contents in the batteries is harmful to the skin; do not touch the leakage with your bare hands directly.
When installing fresh batteries, be sure to clean up the leakage thoroughly.
Note6: Under most circumstances, you only need to point the remote control towards the screen and the IR signal would
be reected off the screen and picked up by the IR sensor on the projector. But under specic circumstances, the
projector may fail to receive signals from the remote control due to environmental factors. When this happens, orient
the remote control at the projector and try again.
Note7: If the range of effective remote control signal reception decreases or if the remote control stops working, replace the
batteries.
Note8: If the infrared receiver is exposed to uorescent lamp or strong sunlight, the remote control may not operate
normally.
Note9: Refer to the regulations enforced by your local government on the disposal of used batteries; improper disposal
could damage the environment.
