Is there a master password to Dell projector 1220s projector

Leonard Espinoza,
Try deleting the password from the information below. If needed you may need to call Dell Support for resetting information.
PASSWORD-When Password Protect is enabled, a Password Protect
screen requesting you to enter a password will be displayed when
the power plug is inserted into the electrical output and the power
for the projector is first turned on. By default, this function is
disabled. You can enable this feature by selecting Enabled. If the
password has been set before, key in the password first and select
the function. This password security feature will be activated the
next time you turn on the projector. If you enable this feature, you
will be asked to enter the projector's password after you turn on the
projector:
1 First time password input request:
Go to Menu Settings, press and then select Password to
enable the password settings
Enabling the Password function will pop up a change screen. Key
in a 4-digit number from the screen and press To confirm, enter the password again.
If the password verification is successful, you may resume with
accessing the projector's functions and its utilities.
2 If you have entered an incorrect password, you will be given two more
chances. After three invalid attempts, the projector will automatically
turn off.
3 To disable the password function, select the Disabled option to close
the function.
4 To delete the password, select the Delete option.
CHANGE PASSWORD-Key in the original password. Then, enter the
new password and confirm the new password again.
