Initially Released Chassis
The keypad features six individual key switches with a positive 'click' action – this provides the
user with tactile feedback. The function of these keys is as follows:
ENTER
[ENT]
CLEAR
[CLR]
(Left, Right)
[←] [→]
(Up, Down)
[↑] [↓]
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
IMPORTANT many digits, such as frequency or data rate.

ENTER [ENT] is used to select a displayed function or to execute a modem configuration change.
CLEAR [CLR] is used to back out of a selection or to cancel a configuration change that has not
been executed using ENTER [ENT]. Pressing CLEAR [CLR] generally returns the display to the
previous selection.
These arrows are used 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.
These arrows are used primarily to change configuration data (characters or numbers). At times,
they may also be used to move from one menu section to another.
