f The adjustment can be performed faster by pressing and holding asqw for approximately three seconds or longer while adjusting the
focus and shift.
f It is recommended that images be projected continuously for at least 30 minutes before the focus is adjusted.

displayed characters are unreadable. (Factory default)
The display color of [FOCUS] depends on the setting of the [DISPLAY OPTION] menu → [ON-SCREEN DISPLAY] → [OSD DESIGN].
f When the power is switched off during focus and shift adjustment, lens calibration needs to be performed the next time the power is
switched on. (x page 144)

adjustment. Execute the [PROJECTOR SETUP] menu → [LENS CALIBRATION].
f When the lens calibration error is displayed even though [LENS CALIBRATION] was executed, ask your dealer to repair the unit.
