FSG 90 System
2 General Description
December 2014 FAV_D10024 7
AVERAGE DEPTH OF MODULATION of some 80% AM, causing transmission signals
sounding normal and very strong.
The radios are equipped with a time out timer. This avoids blocked channel after 2
minutes continuous TX (stuck button does no longer block a channel continuously) and
is indicated by a continuously blinking display. Should the malfunction continue the
FSG 90(X) is ready for another 2 minutes transmission period when turning OFF and ON
again (e.g. for emergency transmissions).
The transmitter blocking feature avoids transmission on a busy channel. Transmitter
blocking is usually active, but may be disabled permanently in SET-UP or manually by
pushing the SQ button.
