For approximately 15 seconds after the projector is switched off, the indicator does not light up even if the power is switched on. Turn on the
power again after the power indicator <ON (G)/STANDBY (R)> lights in red.
f
The projector consumes power even in standby mode (power indicator <ON (G)/STANDBY (R)> lit in red). Refer to operating Instructions
“Power consumption” for the power consumption.
f
When the projector receives the signal from the remote control, the power indicator <ON (G)/STANDBY (R)> will blink in the following color
according to the status of the projector.

However, if the [PROJECTOR SETUP] menu → [STANDBY MODE] is set to [ECO], the indicator will stay lit in red and will not blink if the
projector is in standby mode.
f
The power indicator <ON (G)/STANDBY (R)> will blink slowly in green while the shutter function is in use (shutter: closed), or while the
function of the [PROJECTOR SETUP] menu → [NO SIGNAL LIGHTS‑OUT] is operating and the light source is turned off.

Turn the <MAIN POWER> switch to <OFF>, and cooling fan repair.
*1 The operating environment temperature should be between 0 °C (32 °F) and 45 °C (113 °F) if the projector is used at an altitude between 1 400 m
(4 593') and 4 200 m (13 780') above sea level.

Turn the <MAIN POWER> switch to, and turn on the power again.
Blinking in red
(1 time)
f
The light source is turned off since
the projection lens cannot be
detected.
f
Turn off the power and mount the projection lens again.
f
Turn the <MAIN POWER> switch to <OFF>, and turn on the power again.
Blinking in red
(2 times)
f
The light source does not light up,
or the light source turns off while the
projector is in use.
f
Turn the <MAIN POWER> switch to <OFF>, and turn on the power again.

Note
f
The light source indicator corresponding to the light source being lit will light up in green if the projector is in projection mode and there is no
indication of problem by lighting or blinking in red.
