You will be asked to enter the current password before changing to a new
one. See
"Utilizing the power-on lock function" on page 25 for details.

Limits use of the projector to only those who know the correct password.
When the function is activated for the first time, you have to set a
password for it. See
"Utilizing the power-on lock function" on page 25 for
details. Once the password is set and this function is selected, the projector
is password-protected. Users who do not know the correct password can
not use the projector.
The password can be entered by using either the buttons on the projector
or the remote control.
You will be inconvenienced if you activate the power-on lock
functionality and subsequently forget the password.
Print out this manual (if necessary) and write the password you used
in this manual, and keep the manual in a safe place for later recall.
The password will display as asterisks on-screen when being input.
