looking at the lens.
The POWER indicator lit in green will start to blink in blue.

After you turn on your projector, ensure that the computer
or video source is turned on.

is being input (by factory default menu settings).

Performing Lens Calibration

a lens unit, perform [LENS CALIBRATION] by holding to press
ZOOM/L-CALIB. button on the cabinet over two seconds.
