Fine-tuning the Projector

Using the Projector’s Security Features
To prevent unauthorized use of the projector, you can do the
following:
■
Create an identifying user logo that is displayed at startup and/or
when the
A/V Mute
button is pressed
■
Assign a password; this can be disabled for a set period if you want
to loan the projector to someone
■
Disable the projector’s buttons; this is useful, for example, if
you’re projecting in a classroom and you want to ensure that no
one touches the projector’s buttons while you’re using the remote
control
If you create a user’s logo for the projector, you can lock the logo on so
it is displayed as the startup screen and/or AV/Mute screen.
Unauthorized users cannot turn it off or change it. This feature is
intended to discourage theft and provides a way to identify the
projector should it be stolen.
If you assign the projector a password, a screen appears requesting the
password whenever the projector is turned on. If you enter the
password incorrectly three times in succession, the projector’s
operation is locked and you’ll need to disconnect the power cord, then
reconnect it to redisplay the password screen. If you enter the
incorrect password 30 times in succession, the projector is locked and
you’ll need to contact Epson to unlock it. See “Where To Get Help”
on page 121.
If someone else will be using the projector for awhile but you want to
make sure that person returns it by a certain time, you can temporarily
disable the password for a set period. When that time has elapsed, the
password is reactivated and must be entered before the projector can
be used.
When you enable the Operation Lock feature, all of the projector’s
buttons are disabled except the
P Power
button.
note
If you enable the password
before you set one and you
see the prompt to enter the
password, enter the default
password
0000
to proceed.
