Managing Users (Password Protection)
When Password Protection 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 function as
the projector cannot be used even if it is stolen. At the time of purchase,
Password Protection is not activated.

according to how the projector is being used.

after the projector is plugged in and turned on (this also applies to Direct
