enabled. For example, to enable Level 2 security for the
<
CONFIGURE
> menu, view CONFIGURE: from the
<
PASSWORD
> menu; then change the OFF to ON.
Changing the System Key
To change the System Key, (assuming you have not yet
entered the System Key):
1.
Enter the present System Key. After all four characters
have been selected, press Change/Save. The words
“Sys Key Accepted” will appear in the display screen.
After a short period, the words “System Key” will be
displayed.
2.
Press the Change/Save key to indicate that you wish to
make a change.
3.
Enter the new key. After all four characters have been
selected, press Change/Save. The words, “Re-enter
xxxx” will appear.
4.
Verify correct entry by entering the new System Key
once again. After all four characters have been
selected, press Change/Save.
If your first and second attempts do not match, you will see
the words, “Verify failure” and you will be returned to step
2. When you have successfully entered the new System
Key twice in succession, the display screen responds with
“Sys Key Changed.”
4.6.4 Using the MJ-5 Control Panel With
Password Security Activated
MJ-5 Security does not restrict data reading. However, if
password security is active, you must first enter the proper
password before you can change or reset protected data. If
you attempt to change a password-protected item without
first entering the proper password, the display screen
responds “PW NOT ENTERED” and you must use the
<
PASSWORD
> menu to enter the appropriate password.
Note that a Level 2 password includes Level 1 access
privileges. Therefore, data items that are only Level 1
protected can be changed or reset after you enter either the
Level 1 password or a Level 2 password. Data items
contained in menus that are password protected by Level 2
passwords can only be changed or reset after you enter the
Level 2 password for that menu.
Entering passwords
You can go directly to the <
PASSWORD
> menu and enter
the password(s) you want, or when viewing a specific menu
item, press Cancel/Reset or Change/Save. If password
protection is enabled for this menu, you are prompted to
enter the password. (If you see the password prompt, skip
step 1 below.)
1.
Use the Menu and Scroll keys to view the
<
PASSWORD
> menu. Press the ▼ key. The display
screen responds: “Enter PW xxxx”.
2.
Press the Change/Save key. The display screen
responds by flashing “■” in the leftmost position of
the four character password field. This represents the
character to be entered.
3.
Use the ▲ and ▼ keys to step through the alpha and
numeric characters until the desired character is
presented in the display screen. Press the ► key to
move the cursor to the next character to the right, and
so on until all four characters of the password have
been entered.
4.
When you have completed entering the password,
press the Change/Save key.
(If you started in the <
PASSWORD
> menu, go to step 6.
Otherwise, go to step 7.)
5.
If you entered a valid password, the MJ-5 briefly
displays “PW Accepted”, and then displays “Enter
PW”. This allows you to enter additional passwords.
(You may wish to enter additional passwords if, for
example, you have enabled both Level 1 and Level 2;
or if you have enabled Level 2 and have different
passwords for each menu.) When you have entered all
passwords, you can use the Menu and Scroll keys to
view the data item(s) you wish to change or reset. Skip
step 7.
6.
If you enter the correct password, the MJ-5 briefly
displays, “PW Accepted” and then returns to the
screen you were viewing when you started this
process. If you enter a valid password, but not the
correct password for this menu, the MJ-5 displays
“Enter PW:” again. This process repeats until you
enter the correct password for this menu.
Once a password has been accepted, changes and resets are
permitted for the remainder of the session. To end the
session, view End Session in the <
PASSWORD
> menu,
and use the Change/Save and Scroll keys to change the
default N(o) to Y(es). If you leave the session enabled (un-
terminated) the MJ-5 automatically terminates it when the
screen time-out period expires (see <
CONFIGURE
> menu
Screen t.o. data item).
