conceals some of the system
management settings.

On the fmGenie transmitter the 3.5mm
socket can be used to connect directly to a
TV SCART or similar signal level. The
microphone normally remains live allowing
talkover but can be muted if required.
Microphone options
The fmGenie transmitter may be
used with any of the wide range of
external microphone options or
the internal microphone.
External microphones use a
2.5mm connection. This
connection is also used for
an aerial when using the
internal microphone.
The fmGenie receiver also
has an environmental
microphone facility.
Audio output
modes
The fmGenie receiver has
two audio output modes;
‘High level ’ for neck loop
or headphones and ‘Low
