Operation of theEUIPMENT or SYSTEMbelow this amplitudeor value
may cause inaccurate results.
Warning:
The use ofACCESSORIES, transducers and cables other than those
specified, with theexception of transducers and cables sold by the
manufacturer of theEQUIPMENT or SYSTEMas replacement partsfor
internal components, mayresult in increased EMISSION or decreased

General
Diagnostic ultrasound has been in use for over 25years with no confirmed
adverse effects on patients or instrument operators at the intensities
typical of present diagnostic instruments. Although the total absence of
adverse effects to human subjects after such extensive use at diagnostic
power levels is gratifying, available data are not conclusive and the
possibility that biological effects may be identifiedin the future remains.It
is therefore deemed desirable by medical and other scientific authorities
in this field that exposure to ultrasound should be limited to the duration
and intensity appropriate for the clinical objective. Because fetal tissue
could be more sensitive to biological effects by reason of pregnant
subjects be kept toa minimum.
At present, there is a clear consensus that the benefits to patients of
prudent use ofdiagnostic ultrasound outweighthe risks, ifany, thatmay be
present.
AngelSounds JPD-100S is a portable battery operated detector designed
for the detection of fetal life and confirmation of continued life during
Ultrasound safety
considerations and data
Operation procedure
Insert the headset jacksecurely into the socket(3).
Apply a small amount of acoustic coupling gel to the examination site. Or
put some of gel,oil or water onthe top ofthe transducer(4).
Switching on On/off/volumekey(1)
'On/off/volume key(1)' isused to selecteither high orlow volume level,too.
Hold the AngelSoundsJPD-100S.
The AngelSounds JPD-100Sis now ready foruse .
Examination
Place the transducer on the examination site and move it around slowly
until a good signal is obtained. This will sound like 'galloping horses'. It
may be necessary to angle the transducer slightly to obtain the optimum
signal.
Use of audioline
Insert one jack of the audio line into the main unit's headset socket
(anyone of the two),put another plug intothe recorder, thenthe fetal heart
beat can berecord by recorder.
Move the transducer to pregnant woman's left chest to record her heart
beat and play the mother's heart beat to the baby after the baby is born,
this can calmthe baby.
To switchoff turn 'on/off/volume key(1)' .
Battery fitting orreplacement
To fitor replace the batteryon the AngelSoundsJPD-100S:
Remove the rear battery compartment cover(5) carefully . Remove the old
battery. Fit the new battery (IEC6F22 9V alkaline). Then off the battery
cover.
·Use only the specifiedbattery type and insertthe battery according
to polarity instruction
·Always dispose ofempty batteries inaccordance
with regulations. Donot dispose together
with household garbage
New alkaline battery willgive more than 500one minute examinations.
Battery should beremoved if theunit is not in regular use.
After use, the Angelsounds JPD-100S should be dried thoroughly with a
soft cloth.
If Angelsounds JPD-100S is soiled after use, follow the cleaning, and
disinfection procedure detailedin the preventive maintenance section.

Minimizing patient exposure
Acoustic output of the AngelSounds JPD-100S is internally controlled and
cannot changed by the operator in the course of the examination. The
duration of sure is, however, fully under the control of the operator.
Mastery of the techniques described in the operating instructions will
facilitate limit the maximum amount of diagnostic information with the
minimum of exposure.
Acoustic output data
The acoustic output of the AngelSounds JPD-100S transducer has been
measured in water using a calibrated hydrophone at Authorized
Laboratory. Normalized values, which estimate the maximum 'in-situ'
dosage to tissue at the point of highest intensity in the beam path have
been calculated.
These data are presentedin the following tables.
