7.1.2 6-Button Keypad
The keypad on the front panel contains six individual key switches
with a positive “click” action for tactile feedback.
The keypad has an auto-repeat feature. Holding a key for more than 1 second
repeats the key action 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.
The function of these keys, and their reference throughout this chapter, is as follows:
