Turn the trackwheel clockwise to bring the trackwheel to the end, then slowly rotate
the trackwheel counterclockwise. At the same time, carefully observe the pixels on
the screen. When the image particles are the clearest (Subjected to the middle of
the image), the pixels on the screen are the best focus of the lens.
When the projector is connected to a power source, the projector enters standby
and the cover signal indicator is red.
Power on: Press the power key on the body or the power key on the remote control,
the indicator will turn blue and enter the working state.
Power off: In the working state, press the power key of the body or the power key on
the remote control, the indicator changes from blue to red, and the projector is
turned on.
Focus Adjustment
Turn the Projector ON/OFF
Keystone
If a projected picture has keystone distortion, please correct the image with keystone
adjustment. The image will become a trapezoid shape when the screen or projector
is not level. Please reposition the projector to improve its angle to the screen.
However, the circumference of the image may not be focused.
If you are unable to use the keystone correction function to correct the trapezoid
distortion, please lower the projector to the center of the screen vertically.
