Figure E-1. 7855 Front Panel
There are four round buttons with arrows on their tips (see Figure E-1). They are
used to move around in the configuration menus and to make configuration
selections as you move around. You use one by pressing and then releasing it and
if you use one at a time, they do the following:
←
This button is analogous to an Enter or Run button. Use it to put your
configuration choices into working memory unless you are in the view-only
menu. You can also use it to make the modem start a test or start dialing a
number.
↑
This button is used to select one out of several choices. When the choices
are numerical, this button increments the numbers.
↓
This button is also used to select one out of several choices. When the
choices are numerical, this button decrements the numbers.
→
This button makes the modem show additional detail. When the LCD is
showing a multiple-digit field, this button moves the cursor one position to the
right. Use this button to find out if there are additional configuration choices
in a category.
If you press and release any of these buttons quickly, the display moves one
position in the tree structure. If you hold one of the buttons pressed for more than
approximately one second, the display will start to change quickly as it moves
through multiple positions in the tree structure.
Attention: Pressing the
←
button may change configuration parameters.
