MODEM 32144
Numbered Pushbuttons
Pushbuttons 1, 2, and 3 correspond
to segments 1, 2, and 3 of the LCD
screen. These segments (left,
middle and right positions of the
LCD screen) are numbered on the
modem’s front panel. To make a
selection from a menu screen,
simply push the button with the
same number as the selection
you want.
With respect to how the LCD
flow chart is organized,
pushbuttons 1, 2, and 3 will either
take you to a lower level—or, where
there is no route to a lower level,
they will select an option.
ENT Pushbutton
To exit from a displayed screen,
press the ENT (enter) pushbutton.
With respect to how the LCD flow
chart is set up, pushing the ENT
button will move you upward
through the chart (toward the
MAIN MENU). If you become
lost, pressing the ENT button
repeatedly will return you to screen
1 of the MAIN MENU. Pressing
ENT repeatedly after you have
arrived at MAIN MENU screen 1
will cause the LCD to alternate
between the EIA status screen and
the MAIN MENU. (In the case of
most tests, the ENT button cannot
be used to exit the test screen once
the test has been activated; you
must first press the ENT button
and then select OFF to end the test.)
3.3 Selecting Options from the Front
Panel
This section applies to all option
screens on the front panel LCD
except the Summary Setup screens,
which are explained in
Appendix B
.
Options are accessed from the
SETUP menu. As shown in the
LCD flow chart, the SETUP menu
consists of six screens and is
accessed from screen 2 of the
MAIN MENU. (With screen 2
of the MAIN MENU displayed,
push button 1 to select SETUP.)
Once you have located the screen
that displays the option you want to
access or change, select your choice
by pushing the button with the
same number as the selection you
want. Each selection on the bottom
line of the LCD is numbered either
1, 2, or 3 on the modem’s front
panel (not on the LCD), as shown
in
Fig. 3-2
