"40" [CR] Status: Processing Count Down When "Display" in Setting Menu is On and Power On is executed, it starts processing Count Down. Also, when "Display" Off in the Setting Menu is set, processing Count Down is skipped and the status moves to Power On quickly. 7.3.4. "20" [CR] Status: 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. 7.3.5. "10" [CR] Status: Abnormal power supply voltage When the power supply voltage inside the Projector reaches abnormal power supply voltage, the power will be automatically turned off. The Projector returns "10" [CR] and cooling fan is also stopped at the time. 7.3.6. "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. 7.3.7. "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. 7.3.8.
