System Lock Function
This function prevents unauthorized use of the
projector. Once this function is activated,
users must enter the correct keycode each
time the projector is turned on. We suggest
you record the keycode in a safe place
where only authorized users have access.
Info
• If you lose or forget your keycode, contact
your nearest Sharp Authorized Projector
Dealer or Service Center (see page
71). Even
if the product warranty is valid, the keycode
reset will incur a charge.
