Maintenance
Do not place the device in direct sunlight, or in close proximity to
an intense heat source. Excessively high temperatures may
damage the internal electronics.
Do not under any circumstances dismantle or alter the device, as
this could result in electric shock or injury as well as adversely
affect the precision of measurements.
The device is intended for indoor use only.
Device does not require routine user maintenance. However,
regular checking of accuracy is recommended; frequency to be
determined by level of use and state of device, or local
metrology/measuring instrument regulations if applicable. If
results are inaccurate, please contact local distributor.
Observe permissible ambient temperatures for use
The device has an expected service life of 5 years when correctly
handled, serviced, and periodically inspected in accordance with
manufacturer's instructions.

6
Disposal
This product is not to be treated as regular household waste, but
should be taken to a designated collection points for electronics.
Further information should be provided by local waste disposal
authorities.
Caution
Usage of Results
The U310/B310 is not a diagnostic device.
BIA results are calculated based on impedance values validated
with representative population studies and statistical analysis. As
such, the technique is best suited for tracking progress for an
individual over a period of time, or for categorizing large groups of
people, rather than used as a one-time analysis. Accuracy of
results is highly dependent on proper measurement procedure.
Please follow instructions carefully for best results.

Interference may occur in the vicinity of
equipment marked with the following
symbol:
NOTE1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio
(cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess
the electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which the
device is used exceeds the applicable RF compliance level above, the device should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the device.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.

Recommended separation distance between portable and mobile RF communications
equipment and the Device
The device is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the device can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the device as recommended
below, according to the maximum output power of the communications equipment.
