• This projector employs a microcomputer. Excessive external electrical and RF noise may
cause it to lock up. If this happens, turn the unit off, disconnect the power, wait at least
ten seconds and then re-power the unit. Check the projector's operation again and if
problems persist, contact your dealer.

Setup menu to ensure that images
