Do not touch the lens directly with your hand.
If fingerprints or stains are left on the projection lens surface, they may interfere with the
projector’s ability to project images on the screen.
If the lens cover is closed while in use, after a moment the power will turn off, then the

Turning the power off
1
Press the ON/STANDBY button.
When the beep sound setting is [
On
], the projector beeps, and a message appears,
confirming that you wish to shut off the power. To shut off the power, press the
ON/STANDBY button again. If you do not wish to shut off the power, wait for a while
without conducting any operations. The message will disappear after a moment and
the operation will no longer be valid.

When the beep sound setting is [

the internal cooling fan continues to operate. The projector will then go into standby mode.
During cooling, the ON/STANDBY indicator flashes. While the
indicator is flashing, the power cannot be turned back on. There is
no problem with unplugging the power cord or turning off the main
power switch in this state.
3
Close the lens cover.
After use, close the lens cover.
Note
The projector consumes about 5 W of power in standby. We recommend that you unplug
the power cord if you will not be using the projector for an extended period.
Precautions
If you wish to restart the projector again right after turning off the power, give the lamp time
(about 5 minutes) to cool before plugging it back in. If the lamp overheats, it may fail to light.
Right after turning off the power, the unit may become very hot, especially air exhaust,
lamp cover or the bottom of the unit. Please handle with care to avoid burn injuries.
