Connect the
transmitter with
the elastic belt.
Use the adjusting
mechanism to
individually adapt
the length of the
belt.
Ensure that you
set the length of
the belt so that it
sits well but is not
too tight.
Place the belt
such that for
men the
transmitter is
below the chest
muscles and for
women below
the breasts.
The SIGMA logo
must always be
readable from
the front.
