If something happened with PA loading (for example),
protection circuit detects increasing of VSWR (reflected
power). If this parameter exceed the limit value, fault
condition appears and PA will be immediately blocked.
Top picture shows such a situation. Fault LED is ON,
transmitting is blocking. Under FAULT LED exceeded
parameter is visible (SWR).
Touch RESET to reset fault status and return PA to the
operation mode. Press PTT again to be able to transmit.
Bottom picture shows the cause of this fault status. VSWR
exceeded the limit (1.9:1).
This picture is visible on the display only very short time after
fault condition appears.
