GROUP 3—DIAGNOSTICS
Operating Status
This screen displays three key operating conditions of the radio: TX key status,
Received Signal Strength Indication (RSSI), and Signal-to-Noise (S/N) ratio. Unlike
other screens, the information shown on the Operating Status screen is preserved
across power outages and radio switchovers. This screen has no timeout and will
show until changed by an operator.
Active Radio
Status
Use this screen to show alarm conditions, if any. Major and minor alarm events are
listed in
Table 13 on Page 57
.
If there have been alarm events, press ENTER to show the first alarm. To scroll
through the list of alarms, press the right
or down
arrow button. Pressing
ESCAPE returns the radio to the Active Radio Status screen.
Receive Signal
Strength
This screen displays the received signal strength in dBm.
In a typical master station configuration, the received signal strength is read from
each remote radio that transmits to the master station.
