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. 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 <PASS-
WORD> Menu. Press the Ú key. The display screen
responds: "Enter PW xxxx".
2. Press the Change key. The display screen responds
by flashing "n" in the leftmost position of the four
character password field. This represents the charac-
ter to be entered.
3. Use the Ù and Ú keys to step through the alpha and
numeric characters until the desired character is pre-
sented in the display screen.
4. Press the Ø key to move the cursor to the next char-
acter to the right, and so on until all four characters of
the password have been entered.
5. When you have completed entering the password,
press the Save key.
(If you started in the <PASSWORD> menu, go to step 6.
Otherwise, go to step 7.)
6. If you entered a valid password, the MJ-X
plays "PW Accepted", and then displays "Enter PW".
This allows you to enter additional passwords. (You
may wish to enter additional passwords if, for exam-
ple, you have enabled both Level 1 and Level 2; or if
you have enabled Level 2 and have different pass-
words 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.
7. If you enter the correct password, the MJ-X
displays, "PW Accepted" and then returns to the
screen you were viewing when you started this pro-
cess. If you enter a valid password, but not the cor-
rect password for this menu, the MJ-X
"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, Scroll, and Save keys to change the
default N(o) to Y(es). If you leave the session enabled
(un-terminated) the MJ-X
when the screen time-out period expires (see <CONFIG-
URE> Menu Screen t.o. data item).
