Indication Example
Meaning
Alarm:
An emergency signal has been detected.
The source, the counter of the elapsed time since the last
alarm, and the related frequency are shown beside the
actual alarm indication.
The hotkey “Clr” deactivates the warning signal and the
alarm relay output.
Error:
An error message will be displayed if:
o
one or more operating parameters are out of the
admitted limits
o
the system has recognized a malfunction (in this case
the system is not working)
The hotkey “Clr” deactivates the acoustic warning.
Warning:
The system indicates a warning, if:
o
external signals are not available (anymore)
o
operating parameters are close to the tolerable limits
The warning means that the system’s basic functions are not
affected yet, but it is recommended to check the system in
order to prevent damages.

The following table explains the use of the keypad elements in the “Frequency/Channel Input”
