Keypad - Comtech EF Data LBC-4000 Installation And Operation Manual

6.2.3 Keypad

See Item 4, Figure 6-1 and Item 5, Figure 6-2.
The keys for the current production unit keypad have a positive 'click' action that provides tactile
feedback. Enter data via the keypad. Data, prompts, and messages are displayed on the VFD.
Operation of the individual keys is as follows:
•
Use the [ENT] (ENTER) key to select a displayed function or to execute a unit
configuration change.
•
Use the [CLR] (CLEAR) key to back out of a selection or to cancel a configuration
change that has not been executed using [ENT]. Pressing [CLR] 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.
•
Use the [] (UP) and [] (DOWN) keys to change configuration data (numbers). You
may also use these keys to move from one section to another.
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 the IP Address assignments.
