Function
All tones have the same standard
pitch. Tone duration changes with
the strength of the target signal
(e.g. the stronger the target
signal, the longer the duration).
The tone duration changes, but
the pitch remains the same (e.g.
a small target produces a quick,
standard tone; a medium target
produces a medium, standard
tone; a large target produces a
long standard tone).
The tone of the detector changes
to indicate the conductivity of
the target (e.g. low conductivity
produces a low tone; medium
conductivity produces a standard
tone; high conductivity produces
a high belltone).
The tone duration varies with size
and pitch varies with conductivity
(No belltone signal produced
when Profile is being displayed).
