Turning Off the Projector

If you want to turn off the projector for a short period of time, press the standby button on the keypad or remote. This blanks the screen for fifteen minutes, but keeps the projector running. (You can change the amount of time the projector stays in standby mode; see “Standby Time” on page 30 for details.) After 15 min- utes, the lamp goes out (the projector keeps running). To exit standby mode, press the standby button again. (It may take sev- eral seconds for the projection lamp to reach full power and project the image again.)

To completely power off the projector, press the “O” side of the power switch on the side of the projector. If you want to turn the projector back on immediately, you must allow about a minute for the lamp to cool. The lamp won’t light if it’s too hot.

CAUTION: When you discon- nect the projector after you have switched it off, always remove the power cord from the electrical out- let first, then remove it from the projector.
