Note: If the projector does not respond to the remote control, make

sure batteries are installed and the switch on its side is turned on.

The projector also might not respond if the batteries are weak,

you’re standing at too great a distance from the projector, ambient

light is too bright, a certain type of fluorescent light is present, a

strong light source (such as direct sunlight) shines into the infrared

receiver, or other equipment emitting infrared energy is present

(such as a radiant room heater).

Using the Control Panel

This table summarizes the functions of the buttons on top of

the projector.

Controlling Multiple Projectors

If you’re using more than one projector for your presentation,

you can use the projector’s ID system to switch between them

using a single remote control. To do this, you need to set a

different ID for each projector. During the presentation, it’s

easy to change the remote control’s ID to match that of the

projector you want to use. When you want to switch, simply

change the remote control’s ID to match that of your second

projector.

Setting the Projector ID

The projector’s default ID is 1. If you need to change it,

follow these steps:

1. Access the projector’s Advanced2 menu, highlight

Projector ID and press Enter.

2. Press the right or left side of the pointer button to

increase or decrease the ID value.

3. Press

Enter to set the value.

4. When done, press
