Replacing the Battery
Caution
When replacing batteries, take the following precautions:
❏
Replace the battery as soon as it runs out. If the battery leaks,
wipe away battery fluid with a soft cloth. If fluid gets on your
hands, wash them immediately.
❏
Do not expose batteries to heat or flame.
❏
Dispose of used batteries according to local regulations.
❏
Remove the battery if you won’t be using the projector for a long
period of time.
Follow these steps to replace the battery:
1. Press the tab towards the center of the remote and slide the
battery tray out of the remote control.
2. Remove the old battery and insert a CR2025 watch battery
as shown.
3. Slide the battery tray back into the remote until it clicks into
place.
Using Password Protection
If you assign a password for the projector, a screen appears
requesting the password whenever the projector is turned on.
If the password is entered incorrectly three times in succession,
the projector’s operation is locked. To try again, the user needs
to disconnect the projector and reconnect it. If an incorrect
password is entered nine times in a row, the projector is locked
and remains locked until an authorized person at EPSON can
unlock it.
You can also create a user’s logo for the projector, to be
displayed as the startup screen and/or AV/Mute screen.
Unauthorized users cannot turn it off or change it. This feature
discourages theft and provides a way to identify the projector
should it be stolen.
Additionally, to make sure a borrowed projector is returned,
you can temporarily disable the password for a set period of
time. When that time has elapsed, the password function is
reactivated and the password must be entered before the
projector can be used.
Follow the instructions below to first set the password, and then
turn on the password and/or user logo protection. Be sure to set
the password before you enable the feature; otherwise, you may
lock yourself out of the projector.
Note
If you should happen to enable the password before you set one, and
you see the prompt to enter the password, enter the default password
0000 to proceed.
Setting a Password
1. Press the Freeze button on the remote control for about
7 seconds, until you see the Password Protect menu:
If a password has already been set, you see the Password
Protect Release screen. See “Starting the Projector with a
Password” in the next column.
2. Select
Password and press Enter. You see the message
Change the password?
