Using the Control Panel
This table describes the functions of the control panel buttons. 
Controlling Multiple Projectors
If you’re using more than one projector, you can control all 
the projectors—or just selected ones—by using the projector 
ID system with just one remote control. To operate a 
projector, you have to set the remote control’s ID to match 
that of the projector. Or you can control all of the projectors 
simultaneously by setting the remote control’s ID to zero. 
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 
ESC to exit the menu system.
Setting the Remote Control ID
The remote control’s default ID is zero. If you need to change 
it, follow these steps:
1. Press the 
ID button on the remote 
control. You see it light up. 
2. Press one of the numbered 
buttons on the remote 
control to select the desired 
ID (0 through 9). Select zero 
to control all projectors, or 
select a number to match the 
ID of the projector(s) you 
want to operate.
The 
ID button’s light shuts off and the new ID is registered. 
If you would like to check the remote control’s current ID, 
press the 
ID button twice. Count the number of flashes; this 
number corresponds to the remote control’s ID. If it doesn’t 
flash, the ID is set to zero.
