Password Protection

As shipped, the Admin menu password is 0 (zero). This means that you do not have to enter a password
to access the Admin menu. Simply select System\Admin\Login and press Enter. To password-protect
the Admin menu:

Select System\Admin\Password
Enter a numeric password, up to 15 digits long. Then
press Select.
Log out of the Admin menu to activate the password. You

correct password in the Password field.
If the password is lost, access can be restored by setting an internal switch to reset the password to 0.
If the message "Locked out by internal switch setting" or "Calibration is inhibited by switch setting"
appears, the internal switch is set to prevent the password from being changed. Refer to

for more information.
