■ The Trigger out port outputs a 12-volt DC signal when the projector is turned on. This lets a central control system monitor whether the projector is on or off, and can be used to raise or lower your projection screen automatically when the projector is in use.

Connect a 3.5-mm mini jack to the port, as shown.

Installing Batteries in the Remote Control

The remote control uses 2 AA batteries.

Warning: Keep batteries away from children. If a battery is swallowed, contact your doctor immediately.

1. Release the tab and lift open the cover.

2. Insert 2 new AA batteries as shown.

3. Insert the tab on the cover and press it down until it clicks into place.

Aim the remote control at the front or back of the projector. Make sure you are within 30 feet of the projector with the remote aimed within a 30° angle from the infrared receivers.

When you suspect the batteries are weak, take the remote control to a darkened room and press the illumination button. If the buttons do not glow red, replace the batteries.
