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 Password Protect is 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 projectors 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
Epson (see page 57
).
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 projectors operation will be locked.” Contact Epson (see page
57).
