The function of these keys is as follows:
ENT
(Enter)
This key is used to select a displayed function or to execute a modem
configuration change.
CLR
(Clear)
This key is used to back out of a selection or to cancel a configuration
change which has not been executed using ENTER. Pressing CLEAR
generally returns the display to the previous selection.
◄ ►
(Left, Right)
These arrows are used to move to the next selection or to move the
cursor position. Most of the menus (space permitting) include arrow
key hints to guide the user.
▲ ▼
(Up, Down)
These arrows are used primarily to change configuration data
(numbers), at the current cursor position. Occasionally they may be
used to scroll through a number of choices at the current cursor
position. Most of the menus (space permitting) include arrow key hints
to guide the user.
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.
