11 Password protection
The catalog of functions and parameters can
be protected by a (seven-digit) password. To
activate password protection enter a password,
press START to confirm it, and exit the catalog
of functions and parameters. From this point,
the password is requested each time access is
sought to subfunctions of the main functions
(Feature 1, Feature 2, process or Setting). The
password must be entered correctly and con-
firmed by pressing START before the subfunc-
tions can be accessed.
However, depending on the final digit of the
password, certain sections of the catalog of
functions and parameters can be excluded from
password protection.:

Activating password protection
1. Press the MENU key. The catalog of func-
tions and parameters item “FEATURE (1)” is
displayed.
2. Use the DATA and MASTER keys to select
the setting “SETTING (4)”.
3. Press the MENU key. “DISPLAY (4.1)” is dis-
played.
4. Use the DATA and MASTER keys to select
the setting “PASSWRD (4.5)”.
5. Press the MENU key. Seven zeros are dis-
played under “PASSWRD”, the first of which
flashes.
6. Enter the password (see section “Changing
numerical values for parameter settings” in
Chapter 0).
When selecting the final digit of
the password, refer to the table
on the left, which indicates the
main functions that will not be
password protected!
7. Press START once the password has been
entered. The password is adopted.
However, password protection
is only activated on exiting the
catalog of functions and param-
eters. As long as the catalog of
functions and parameters re-
mains open after a password
has been entered, changes can
still be made on all levels of the
catalog.
In case you forgot the pass-
word, restore the Mahr factory
settings (cf. Chapter 16).
