the special purpose cable,
cx-13292/vrc, that connects
the ls-6

1/vrc loudspeaker
to the SINCGARS radio,
comes in many lengths.
an added benefit to these multiple
lengths is the flexibility it gives you to
take the pressure off a taut cable.
an 8-ft cable
can bring
relief
to a 6-ft
cable that is
stretched to
its limit.
here’s a list of
the available
lengths for the
cx-13292/vrc
special purpose
cable…
these lengths allow the loudspeaker
to be installed in different
configurations to meet the needs of
different types of vehicles.
…YOU NEED TO ADD AN iMPORTANT
