without permission.
• Anti-Theft Lock

Managing Users (Password Protect)
When the Password Protect function is activated, people who do not know
the password cannot use the projector to project images even if the
projector power is on. Furthermore, the user's logo that is displayed when
you turn on the projector cannot be changed. This acts as an anti-theft
