6.1.2 Front Panel Keypad
The CRS-300 front panel keypad contains six individual key
switches mounted behind a sealed membrane overlay. The keys
have a positive "click" action for tactile feedback.
The keypad has an auto-repeat feature: If a key is held down for
more than 1 second, the key action repeats automatically at the
rate of 15 keystrokes per second. This is particularly useful when
editing numeric fields.
These six switches function as follows:
