'1' SP 'U0F' SP '1' CR '@' '1' SP '0' CR *1 When the POWER ON command is received, the Projector returns the Tally (Response) Data after completing all the POWER ON processing operations (lighting lamp, rotating fans, transmitting data, etc.). In most cases, the Tally (Response) Data should be returned within 35 to 40 seconds. If it takes more time to light up or re-try is done due to internal error , these operations takes maximum around 100 seconds. (The Tally Data is returned within 100 seconds.) *2 When the POWER OFF command is received during Power-ON mode, the Projector enters the cool-down mode (DLA-G3010 series: for about 90 seconds, DLA-M2000L series: for about 120 seconds) and continue cooling (DLA-G20series: for about 120 seconds, DLA-M4000L series: for about 10 minutes). After cool-down mode is completed, the Projector automatically enters the stand-by mode. (For operation modes, 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. (For the command to request the current operation mode, refer to 12.41 Operation Mode Query.) 29
