5.1.3 Keypad
The keypad has an auto‐repeat feature. If a key is held
down for more than 1 second, the key action will
repeat, automatically, at the rate of 15 keystrokes per
second. This is particularly useful when editing numeric
fields with many digits, such as frequency or data rate.
The function of the keypad is as follows:
KEY USE THIS KEY TO...
[ENT]
(ENTER)
...display the nested menu for a selected function, or to execute (save) a configuration change.
[CLR]
(CLEAR)
...back out of a selection or to cancel a configuration change that has not been executed using
ENTER. Press [CLR] to return to the previous menu screen.
[ ←] [→]
(Left, Right)
...navigate between available selections, or to move the cursor position, on any menu screen.
[ ↑] [↓]
(Up, Down)
... scroll through pre-defined parameter settings that are available at the current cursor
position, and to change (edit) the alphanumeric selection (i.e., numbers for configuration data,
letters for text strings) at the current cursor position.
