Shown in Figure 8-2 and as Feature 2 in Figure 8-1 , the function of these keys, and their
reference throughout this chapter, is as follows:
•
Use the [ENTER] key to select a displayed function or to execute a unit configuration
change.
•
Use the [CLEAR] key to back out of a selection or to cancel a configuration change that
has not been executed using [ENTER] . Pressing [CLEAR] generally returns the display
to the previous selection.
•
Use the

(LEFT) and

(RIGHT) keys to move to the next selection or to move the
cursor functions. At times, they may also used to move from one section to another.

also use these keys to move from one menu section to another.
The keypad has an auto-repeat feature. If you hold down a key for more than 1
second, the key action repeats automatically at the rate of 15 keystrokes per
second. This feature is useful when editing a numeric field with many digits, such
as frequency or data rate.
