Each key provides one or more logical functions. These functions are defined in the following
table.
ENTER This key is used to select a displayed function or to execute a modem configuration
change.

not been executed using [ENTER]. Pressing [CLEAR] generally returns the display to the
previous selection.

Diamond Keys These keys are used to move to the next selection or to move the cursor for certain
functions.
Note: Throughout this chapter, [

keys.

Diamond Keys These keys are used primarily to change configuration data (numbers). At times, they are
also used to move from one section to another.

keys.
The modem responds by beeping whenever a key is pressed:
•
A single beep indicates a valid entry and the appropriate action was
taken.
• A double beep indicates an invalid entry or a parameter is not
available for operation.
