Boxlight CD 40m CD-40m User Manual

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

button on the keypad. 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 23 for details.) After 15 minutes, the 
lamp goes out (the projector keeps running). To exit standby 
mode, press the 

button again. (It may take several sec-

onds 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.
