1. Press firmly and slide the battery cover off.
2. Remove both old batteries and install new ones (AA). Ensure that
you have the batteries' polarity (+/-) aligned correctly.
3. Slip the cover back over the batteries until it snaps into place. Do not
mix different types of batteries or new and old batteries.
Note on Remote Control Operation:
If you press and hold the SELECT GHFE button while installing new
batteries, the remote control may fail to work properly.
Should this happen, remove the batteries and then install them again
without touching the SELECT button.
Remote Control Precautions
Handle the remote control carefully.
If the remote control gets wet, wipe it dry immediately.
•Avoid excessive heat and humidity.
If you will not be using the remote control for a long time, remove the
batteries.
Do not place the batteries upside down.
Do not use new and old batteries together, or use different types of
batteries together.
Operating Range for Wireless Remote Control
Remote control
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 re-
mote control and the sensor, or if strong light falls on the sensor.
Weak batteries will also prevent the remote control from properly
operating the projector.
