Status: Standby
When the status is Standby, Status Read Commands are always acceptable, but
Functional Execution Commands are not acceptable except Power ON Command.
8.3.3. "40" [CR]
Status: Processing Count down
When "Display" in Setting Menu is ON and Power ON is executed, it starts
processing Count Down.
When "Display" OFF in the setting menu is set, processing Count Down is skipped
and the status moves to Power ON quickly.
8.3.4. "20" [CR]
Status: Processing Cooling
When status is Power ON, and Power OFF Command is executed, it moves to
cooling status.
This cooling status automatically moves on to Standby after the lamp turns off and
the fan spin for about 90seconds.
This cooling down works for lamps and other optical accessories.
Control commands are not available for this status.
8.3.5. "10" [CR]
Status: Abnormal power
When the power supply voltage inside the projector reaches abnormal, the power
will be automatically turned off. The projector returns "10" [CR] and cooling fan is
also stopped at the time.
8.3.6. "28" [CR]
Status: Processing Cooling Down by abnormal temperature
When the temperature inside a projector is out of the operating temperature, it
automatically starts cooling down. Response is "28" [CR].
Even if the temperature is processing low, the cooling down is executed.
8.3.7. "08" [CR]
Status: Abnormal temperature
When the temperature does not go down after cooling down due to the abnormal
temperature, this is the Response. The projector keeps the Standby status.
8.3.8. "88" [CR]
Status: Normal status after recovering abnormal temperature
When the temperature goes down after cooling down and moving to Standby status,
this is the response.
This status keeps until the next operation. In short, when Power On is executed, the
