1.4.1 Front Panel
The front panel allows control using: four way touch pad, an Enter key, and an Esc key.
Operational commands and parameters are displayed on a graphical LCD. The four way touch pad
allows parameter modification and menu scrolling.
The F1 and F2 keys are short-cut keys, you can use them to perform the following tasks:
■ F1 is the Save/Drop key, use it from any screen or menu on the front panel.
■ F2 is currently active in DSNG modules only. The key sets the Carrier and Modulation Mode
parameters. For details see 3.1.1.1 Front Panel Controls and Displays on page 39.
The alphanumeric touch pad offers an easy-to-use keyboard for using parameters that require
setting a number or a string of characters. The user can directly set values and strings with free-
text using the alphanumeric touch pad.
For details on the touch-pad functionality and front panel components, see 3.1.1.1 Front Panel
Controls and Displays on page 39.
The front panel also contains warning and power/fail LEDs that operate as status indicators (see
3.1.1.1 Front Panel Controls and Displays on page 39).
