Preventing theft (Password Protect)
When the Password Protect function is activated, people who do not know
the password will not be able to use the projector to project images, if the
power has been disconnected since the password was last entered correctly.
Furthermore, the user's logo that is displayed on the background of the
screen cannot be changed. This is effective against theft. At the time of
purchase, the password protection function is not enabled.
When "Power On Protect" is enabled (On)
When the power is turned on for the first time after the projector's power
cable is connected to an electrical outlet, or when Direct Power On is
carried out, the following password entry screen will be displayed.
While holding down the [Num] button, press the numeric keypad buttons
to enter the password. If the password is entered correctly, projection will
start.
If you leave the power cable connected to the electrical outlet and turn the
projector's power on when it is in standby mode, projection will start
without the password entry screen appearing. The password entry screen
will only be displayed when the power is turned on for the first time after
the power cable has been disconnected and then reconnected. If Direct
Power On is set to "On" and you are using a circuit breaker or similar to
centrally control the power, the password entry screen will be displayed the
first time the projector is turned on after the power supply is restored.

• If an incorrect password is entered three times in
succession, the message "The projector’s operation will
be locked." will be displayed for approximately five
minutes, and then the projector will switch to standby
mode. If this happens, disconnect the power plug from
the electrical outlet and then reinsert it and turn the
projector's power back on. A window requesting you to
enter the password will be displayed, so enter the
correct password.
If you happen to forget the password, make a note of the
"Request Code: xxxxx" number that appears in the
Password screen and contact the nearest address
provided in the "International Warranty Conditions"
section of the Safety Instructions/World-Wide Warranty
Terms booklet.
• If you continue to repeat the above operation and input
the wrong password thirty times, the following message
will be displayed and the projector will not accept
password entries any more.
"The projector’s operation will be locked. Contact
Epson as described in your documentation."
