•When the projector is set to “Slave”, operations follow the button operations sent from the “Master”.
•When set to slave, all buttons on the projector along with ENTER, UNDO, POWER, LENS and MENU on the GyroRemote
can be used. The slave cannot operate the other buttons on GyroRemote.
•For details on intended purpose, see pages 
65 and 66.
