Command
PWR ON
PWR OFF (note4)
SOURCE (note3)
All others
(note1) When a projector receives the PWR ON command, it tries to ignite the lamp by activating the ballast unit. In
case that the lamp fails to be ignited, it tries to ignite the lamp three times at maximum. When the lamp fails to be
ignited three times, it is a lamp failure.
The projector returns a colon within 40, 70 and 100 seconds when successful in the first, second and third times
respectively.
(note2) When the input vide sync signal is stable, a colon is returned within 5 seconds. However, it may take more than
5 seconds when the input video sync signal is unstable.
(note3) Projector initiates the process of the input video signal recognition when it receives a SOURCE command. If
the signal of the video input is changing (for example, from SVGA to XGA by A/V controller) during the process of
the input video signal recognition, the projector returns "ERR".
(note4) Projectors execute the PWR OFF command after they start completely.
(note5) Projectors might return "ERR" when "Quick Setup" and "Auto Focus" functions are set to ON.
5.3. Warning and abnormal cases
Projector executes commands normally while a warning indicator such as a high temperature warning is on.
Projector does not execute commands nor return a colon when the projector is in an abnormal state such as a lamp
failure and abnormal high temperature.
As for EMP-6100/6000, EMP-1715/1710/1705/1700, EMP-1815/1810, EMP-S5/X5/83/822 and the following models,
when an abnormal state is continued for 130 seconds after, PWR ON command becomes possible.
