ASSWORD

Protect your projector and restrict access to it with Password
Security feature. This security utility enables you to impose a variety of
access restrictions to protect your privacy and stop others from tampering
with your projector. This means that the projector cannot be used if it is
taken without authorization, and thus serves as a theft-prevention feature.
When Password Protect is enabled (
On ), a Password Protect screen
requesting you to enter a password will be displayed when the power plug is
inserted into the electrical outlet and the power for the projector is first
turned on. By default, this function is disabled. You can enable this feature
using the Password menu. This password security feature will be activated on
the next time you turn on the projector. If you enable this feature, you will
be asked to enter the projector's password after you turn on the projector:
