The keypad has an auto‐repeat feature. When 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...
ENTER
...display the nested menu for a selected function, or to execute (save) a configuration change.

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 or, if pressed repeatedly, to the
opening screen. From the opening screen, press CLEAR once to display the SELECT: (Main)
menu.
◄ ►
