III. How to Use
A. Self-calibration
The product may require a quick self-calibration before being used for the
first time to ensure accuracy.
1. Place product on stable, flat, solid, non-slippery surface (no carpet).
2. Step on measurement platform. Weight will be displayed on screen.
3. Step off from measurement platform. After product turns off
automatically after a short period of time, self-calibration is complete.
B. Conducting measurement
Place product on stable, flat, solid,
non-slippery surface (no carpet). To
ensure accuracy, we recommend
performing self-calibration if product is
moved.
Open o'care app on smartphone and
log-in. Results will be automatically
transferred after measurement, so it is
important to select the correct user.
Stand on product for measurement. Try to
stand as still as possible. Weight result will
appear on screen. After weight is
measured, device will measure heart rate
(~15 seconds).
After measurement completion, screen will
alternate display of weight and heart rate.
Product will send results to smartphone.
(please open o'Care app prior to
measurement, to allow product to
automatically pair and sync)
After result transfer is complete, product
automatically shut down.

9
Syncing measurement results
1. If o'care app is not open on smartphone, results will not be
transferred. Product will automatically shut down 30 seconds after
completion of heart rate measurement.
2. Ensure that Bluetooth is enabled on smartphone.

should be used no closer to any
part of the product including
cables, than the recommended
separation distance calculated
from the equation applicable to
the frequency of the
transmitter.
Recommended separation
distance:
d = 1,2 √P
d = 1,2 √P 80MHz to 800 MHz
d = 2,3 √P 800MHz to 2,5 GHz
Where P is the maximum output
power rating of the transmitter
in watts (W) according to the
transmitter manufacturer and d
is the recommended separation
distance in metres (m).
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site surveya,
should be less than the
compliance level in each

frequency rangeb.
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 product
is used
exceeds the applicable RF compliance level above, the product should be observed to verify
normal operation. If abnormal performance is observed, additional measures ma
y be
necessary, such as re-orienting or relocating the product.
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
BHG-208 Cardio Scale
The product is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the
product can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile
RF
communications equipment (transmitters) and the product as recommended below,
according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in metres (m) can be estimated using the equation applicable to the
frequency of the transmitter, where p is the maximum output power rating of the transmitter in
watts (W) according to
the transmitter manufacturer.
