After setting the projector's ID, select the ID for the projector you want to operate using the remote control.
Aim the remote control at the target projector and press the ID button.
While holding the ID button, press the number button that matches the ID of the projector you want to operate.
When you select 0/All on the remote control, you can operate all projectors regardless of the Projector ID setting.
When you set the Projector ID setting to Off, you can operate the projector using the remote control regardless of the ID you select on the remote control.
The projector ID setting is saved in the remote control. Even if the remote control batteries are removed to replace them and so on, the saved ID setting is retained. However, if the batteries are left out of the remote control for an extended period, the ID returns to its default setting (0/All).
When you use multiple remote controls at the same time, you may not be able to operate projectors as intended due to infrared interference.
