voltage changes value indication into ‘HI’ (above 16.1
Vdc / below 16.5 Vdc).
Above approximately 16.5 Vdc, the radio

indication. When supply is reduced to between
16 Vdc and 10.5 Vdc, the FSG 2T comes back into
operation.
Temperature Error: The whole LC display flashes.
Temperature of the Transmitter Power Amplifier is too
high. The keyed transmitter will be disabled. Switch
OFF the radio, wait a few seconds and switch ON
again.

severe process error must have occurred. Try to
revive the radio by switching OFF and ON again.
If the same error occurs contact a f.u.n.k.e.
AVIONICS approved repair facility!

severe frequency error must have occurred. Try to

2 Minutes TOT Time-Out-Timer: After two minutes
continuous transmitting the transmitter of the FSG 2T
switches OFF itself and the whole LC display flashes
as long as the PTT key is pressed.
When the PTT key stuck accidentally it can be
received with the adjusted frequency although the
display is flashing. After switching the radio OFF and
ON again it can be transmitted for another 2 minutes
followed by receive mode.
