When the POWER OFF command is received in the Power ON mode, the Projector first enters
the Cool-Down mode, then automatically enters the Standby mode.
(For information on each operation mode, refer to 10. Projector Operation Modes.)
POWER ON command cannot be accepted in the Cool-Down mode. If POWER ON is requested after
POWER OFF command is sent, firstly the current operation mode should be asked and then if Standby
Mode is confirmed, POWER ON command should be sent.
