3.2 Purpose of use
The medical device is used to determine the weight of lying babies and may only
be used for this purpose. Any other use is prohibited. This scale is intended for use
in custody transfer. It complies with the applicable requirements of EC Directives
2014/30/EU, 2014/35/EU, 20104/31/EU and 2007/47/EC (93/42/EEC).
Notications about errors that could endanger the baby, as well as about errors that
could lead to a falsication of measurement results must be reported in writing to
the manufacturer‘s medical device advisor.
This instruction manual is an integral part of the unit. The exact observance of these
instructions is a prerequisite for the proper use and correct operation of the device.
Please make sure that you do not permanently load the scale. In addition, shocks and
overloading of the scale that exceed the specied maximum load must be absolutely
avoided. This can damage the scale.
The scale may only be used in accordance with the described specications. Devi-
ating areas of use / areas of application are subject to written approval by Soenhle
Industrial Solutions.
Class I medical device with measuring function.
Electrical protection class II (insulated, no protective conductor connection).

the power supply at any time. The accessibility of the socket should be guaran-
teed at all times.
When moving the scale, lift the scale. The scale must neve be pushed. Then
check the levelling and adjust it to the new situation if necessary.
The scale is a measuring instrument. Drafts, vibrations, rapid temperature ch-
anges and solar radiation can affect the weighing result. The scale complies
with protection class IPX2, high humidity, vapours, aggressive liquids and hea-
vy soiling must be avoided.

batteries as hazardous waste at public collection points in your community or
wherever batteries of this type are sold. These signs can be found on batteries
containing harmful substances: Pb = battery contains lead, Cd = battery contains
cadmium, Hg = battery contains mercury.
According to the current stand of knowledge, the device does not contain any spe-
cial environmentally hazardous substances. This product is not to be treated as

The scale is fully assembled on delivery.
Remove the packaging.
Place the scale on a rm, free and horizontal surface.
Make sure that no cables or other objects are trapped under the scale.
Level the scale by turning the foot screws. The air bubble of the level must be
exactly in the middle of the circle.
For exhibition venues in Germany, this is fullled if the floors meet the tolerances for the require-
ments of DIN 18202, Table 3, line 4. For other countries, the respective applicable national standards
can be used as a basis.

>Turn the baby scale over without the infant carrier so that you look at the bottom
of the scale.
> Insert the plug into the power supply connector of the terminal.
You may be able to loosen the screws so that you can remove the terminal. This
gives you more freedom of movement. Once you have connected the charging
unit, return the terminal to its original position and tighten the screws.
>Plug the power supply unit into an electrical outlet.
Please ensure that the socket is freely accessible.

The customer or the user of the 7752 scales should ensure that it is used in such an environment.

Portable and mobile radios shall be
used at no distance from the scale
7752, including the lines, less than the
recommended protective distance,
calculated according to the equation
suitable for the transmitting frequency.
Recommended protective distance:
d = 0,4 √P
d = 0,4 √P
for 80 MHz to 800 MHz
d = 0,7 √P
for 800 MHz to 2,7 GHz
with P as the rated power of the
transmitter in watts (W) as specied by
the transmitter manufacturer and d as
the recommended protective distance
in meters (m).
The eld strength of stationary radio
transmitters is lower than the matching
level at all frequencies according to an
on-site investigation.
Interference may occur in the vicinity of
devices bearing the following symbol.
NOTE 1: At 26 MHz and 800 MHz the higher frequency range applies

absorption and reections of buildings, objects and people.
a) The eld strength of stationary transmitters, e.g. base stations of radio telephones and mobile land radios, amateur radio stations,
AM and FM radio and television transmitters cannot theoretically be precisely predicted. To determine the electromagnetic environ-
ment with respect to the stationary transmitters, a study of the location should be considered. If the measured eld strength at the
location where the instrument is used exceeds the above compliance levels, the instrument should be observed to demonstrate its in-
tended function. If unusual performance characteristics are observed, additional measures may be necessary, e.g. a change or another
location of the device.
b) Over the frequency range 150 kHz to 80 MHz the eld strength should be less than 3 V/m.

Recommended protective distances between portable and mobile RF telecommunica-
tions equipment and 7752 series scales
The scale of type series 7752 is intended for operation in the ELECTROMAGNETIC ENVIRONMENT indicated below.
The customer or the user of type 7752 scales can help to avoid electromagnetic interference by maintaining the
minimum distance between portable and mobile RF telecommunication devices (transmitters) and type 7752 scales,
depending on the output line of the communication device as indicated below.

For transmitters whose rated power is not shown in the table above, the distance can be determined using the
equation associated with each column, where P is the rated power of the transmitter in watts (W) as specied by
the transmitter manufacturer.
NOTATION 1:
To calculate the recommended protective distance of transmitters in the frequency range 80MHz to 2.5 GHz, an
additional factor of 10/3 was used to reduce the probability that a mobile/portable communication device
inadvertently introduced into the patient area would lead to interference.
NOTATION 2:
These guidelines may not be applicable in all cases. The propagation of electromagnetic quantities is inuenced
by absorption and reections from buildings, objects and people.
