Description of the information displayed by the three indicators:

Red HF alarm indicators (RF 3dB):
After exiting the configuration, the control part divides by two the transmitted HF power in order
to estimate the alarm threshold. When the power is lower than this value, the indicator is on and
launches an alarm to indicate a power loss.
Æ
VSWR alarm red indicator:
It lights up and launches an alarm when estimated VSWR value is greater than the indicated
threshold, which indicates an external problem in the operation.
Æ
Green indicator of the synthesized locking (LOCK):
When lit, it indicates that the synthesizer is locked on a frequency.
