projector or remote control to restore the image.
The word '

let the projector return the image automatically after a period of time when there is no action
taken on the blank screen.
Once Blank is pressed, the projector enters Economic mode automatically.
CAUTION

become heated and deformed or even cause a fire.

We recommend you use the
High Altitude Mode
when your environment is between 1500
m–3000 m above sea level, and temperature is between 5°C–25°C.
CAUTION
Do not use the High Altitude Mode if your altitude is between 0 m and 1500 m and temperature
is between 5°C and 35°C. The projector will be over cooled, if you turn the mode on under
such a condition.
