Boxlight CD-450m ユーザーズマニュアル

If you want to turn off the projector for a short period of time, 
press the 

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 

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.
