The
Sonicator
ME 706
has
a special feature, a no-load
sensor,
that
limits
and
cuts
off power automatically if
contact
between
the
transducer
and
the
patient's
skin is
interrupted
for a period of time.
The
buzzer
will
buzz
for
several (about five)
short
buzzes
when
the
automatic no-load
sensor
shuts
off
the
unit. This feature
adds
another
dimension of
protection
against excessive
heat
build-up on
the
ceramic disc. Initial dis-contact
produces
a
drop
in
the
amount
of
current
flowing to
the
disc
and
within
about
3 to 5
seconds,
energy
is totally
cut
off.
Should this feature activate frequently, it may be an indication
that
coupling is either insufficient in quantity,
or
inefficient in performance.
The
lack of
good
coupling may be
caused
by
not
using a
good
coupling agent
such
as Sonigel,
not
using sufficient
amounts
of
the
coupling agent (you
cannot
use
too
much),
or
contact
with a very small
area
such
as
at
the
extremities (hands
and
feet) without
the
use
of copious
amounts
of a coupling agent. When
treating an
area
such
as
a
hand
or
foot, you may
treat
under
water
as indicated
in
the
illustration on
page
8. You may also
use
a
cushion
filled with
the
couplant to
treat
an irregular surface.
Selecting the
proper
couplant insures proper energy transmission, thereby
enhancing
the
efficiency of
treatment
while discouraging energy reflection
back
to
the
disc, causing eventual damage
and
possible depolarization.
NOTE: If unable to resolve a problem with
the
unit,
contact
your dealer,
or
communicate
directly with
the
manufacturer.
