Battery Installation

Press the catch and re-

move the battery cover.

Install new ones (AA). Ensure

that you have the batteries’ po-

larity (+/−) aligned correctly.

Slip the cover back over the bat-

teries until it snaps into place.

NOTE: Do not mix different types of

batteries or new and old batteries.

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 options are: front, rear or both. (

• 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 projector.
