"0000", meaning that there is no password. As soon as you
press the first Arrow key, the display will change to [0000]
and begin showing the actual value of your password entry.
Any initial display other than [3552] signifies that a password
already exists. This means that you will need to change, rather
than enter a new one (see below).
Use the UP arrow and the LEFT arrow keys...
to display the password you desire (Valid range is 0000 to
0999). In this example, 0123 has been selected.

The display will flash [End] to confirm you have entered a
password. Then it will return to displaying thee Function #.

Changing passwords:
To change an existing password, the steps are essentially the same as
outlined above, except you must first enter the existing password. At
F070, press the [READ/ENTER] key to reveal the encoded password
(you must know that password before it can be changed). Use the
Arrow keys to enter the password. As soon as you press the first Arrow
key, the display will change to [0000] and start showing the actual value
of your entry. When you get to the existing password, press the
[READ/ENTER] key again. The display will flash [PASS] to indicate that
the password was accepted. If it flashes [ Err ], you have entered the
wrong password.
Resetting to Factory Defaults using F071 will NOT reset the password.
Disabling Password Protection / Parameter Lockout
Changing function F070 to [0000] will disable the user password. If the
initial display reads [3552], the password is already set to [0000].
