is sent with a 4 to 8-digit password comprised of any gures 1 to 4 added to the end of the data code. When
the password lock is enabled or disabled successfully, the projector sends a return command comprising the
data code, password, and “1” at the end. When enabling or disabling the password lock fails, it sends a return
command with “0” at the end. There is no reconrmation of the password. The password input command is for
