29 Restrictions in the Target Projector when Using Multiple Projectors
When an ID is set for the projector and the remote control, you can use the remote control to operate only the projector with a matching ID. This is
very useful when managing multiple projectors.
You can set an ID for the projector within a range of "1" to "9". The default value is "Off", and you can operate with the remote control regardless
of the remote control's ID setting.
You can set an ID for the remote control within a range of "0" to "9". The default value is "0", and you can operate with the remote control
regardless of the projector's ID setting. Also, if there is an ID switch on the side of the remote control, and this switch is set to "Off", you can
operate all projectors by remote control regardless of the ID setting for the projector or the remote control.
