The default service password is 5566.
Default Factory password is 56789.
If you have lost the level 1 or level 2 passwords the factory password can be used to reset them.
If the password is no longer set to the defaults... you can discover the current password by using the MSLUTIL.exe via a serial connection. There is no need to know the serial settings as the utility will autodiscover them. The current configuration does not have to be reset and the password will be displayed in plain text. You will need the correct serial cable.
