About Direct Power Off
The projector has a feature called “Direct Power Off”. This fea-
ture allows the projector to be turned off (even when projecting
an image) using the Main Power Switch or disconnecting the
AC power supply.
NOTE: Before using Direct Power Off, be sure to allow at least 20 min-
utes immediately after turning on the projector and starting to display
an image.
CAUTION
• Do not unplug the power cable from the wall outlet or projec-
tor when the projector is powered on. Doing so can cause
damage to the AC IN connector of the projector and (or) the
prong plug of the power cable. To turn off the AC power sup-
ply when the projector is powered on, use the Main Power
Switch.
• Do not turn off the AC power supply within 10 seconds of
making adjustment or setting changes and closing the menu.
Doing so can cause loss of adjustments and settings and re-
turn to default.
After Use
Preparation: Make sure that the main power is turned off.
1. Unplug the power cable.
