The keypad features six individual key switches with a positive ‘click’ action – this provides the
User with tactile feedback. The function of these keys are as follows:
ENTER
(ENT)
This key is used to select a displayed function or to execute a modem
configuration change.
CLEAR
(CLR)
This key is used to back out of a selection or to cancel a configuration change,
which has not been executed using ENTER (ENT). Pressing CLEAR (CLR)
generally returns the display to the previous selection.
Left, Right
W X
(←) (→)
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.
Up, Down
S T
(↑) (↓)
These arrows are used primarily to change configuration data (numbers). At times,
they may also be used to move from one section to another.
IMPORTANT
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 frequency or data rate.
