ADJUSTING THE DISPLAY CONTRAST
The user can adjust the display contrast while the 95x is in the base menu state (i.e., the display shows the model
number and the time/date). An example display when the user can adjust the display contrast is
–
Vitrek 951i
9-Feb-10 9:08:51am
Using the Up and Down Arrows keys, select the display contrast which best suits the users normal viewing position.
NOTE
–
it may be possible to adjust the display contrast such that the display is not visible. If the display appears
to be totally blank, then press and hold the Down Arrow key to return it to the visible state; if the display appears
to have all of its dots “black” then press and hold the Up Arrow key to return it to the visible state.
NOTE
–
it may be best to select the contrast which shows the least “blurring” when the secon
ds digit in the
displayed time changes. This has been found to produce the best adjustment for viewing angle as well as contrast.
LOCKING AND UNLOCKING MENUS
Many menus in the 95x can be locked by a user, preventing unauthorized changes to test sequences and
configuration settings via the front panel of the 95x. When initially delivered from the factory, this capability is
disabled.
The password is any combination of six 0 through 9 and A through F characters. The password 000000 indicates a
cleared password, disabling this capability until a non-zero password is subsequently set by the user.
If a menu lock password has been set, the 95x always powers up with the menus locked.
UNLOCKING MENUS
If the menu lock password has been set, a user must enter this password to unlock a menu. The user is prompted
to enter the password when needed, which is accomplished by using the
0
through
9
and
A
through
F
keys as
needed to match the previously set password, followed by the
ENTER
key. After successfully entering the
password the front panel menus remains unlocked until the menus are relocked by the user or the 95x is power
cycled. Note that the 95x display does not show the characters during unlock password entry for security reasons.
