Keypad

See Figure 6-1, Item 3. 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.
