General Instructions
OHS Body Fat Analyzer Figure applies BIA (Bio-impedance Analysis) technology. A small
amount of weak current flows through the human body to detect the bio-impedance and
estimate body fat, total body water, muscle mass, bone mass and BMR. The electrical
current is small and may not be felt.
This BIA technology is cheap, safe, non-invasive, toxic-free and harmless. It also
possesses the characteristics of simple operation and abundant information.
The current mentioned above is less than 0.5mA. However, please be aware that anyone
with a wearable or implantable medical electronic instrument, such as a pacemaker, must
avoid using this device.
The intended use of this device is for healthy children 10-17 years old and healthy adults.
Select Measurement Unit
With batteries correctly installed, press “UNIT” button in the back of the scale to select
measurement unit. The default measurement unit is “lb”. You may press “UNIT” button to
choose between kilogram and pound.
Insert the Batteries
Open the battery door in the back of the scale.
Remove insulating strip from beneath the battery (if
fitted) or insert batteries (2 x 3V CR2032) observing the
polarity signs (+ and -) inside the battery compartment.
* The digits “8888” will be shown on the LCD.
Close the battery door and wait until the digits “0.0” are
shown on the LCD.
Initializing Your Scale
1. Press the platform center and remove your foot.
2. “0.0” will be displayed.
3. The scale will switch off and is now ready for use.
This initialization process must be repeated if the scale is moved.
At all other times step straight on the scale.

CAUTION
When the symbol “Lo” appears, the device will power off. Then you shall replace with a new set of
batteries. Please replace both two batteries at the same time. Do NOT mix the old batteries with the new
one.
Worn batteries are hazardous waste. Do NOT dispose of them together with the household garbage.
Please refer to the local ordinances and recycling instructions regarding disposal of the worn batteries
and scrapped device.
If you do not intend to use this unit for a prolonged period, it is advisable to remove the batteries before
storing.

Note: To update or overwrite the memorized data, follow the same procedure, making
changes as required.
First Measurement
•Position scale on a firm flat surface.
•Press SET key.
•While the user number of the latest measurement is flashing, select your user number by
pressing or key. After 3s, the selected number is locked, the scale shows zero
reading.
(Note: When the user number is flashing, if you press SET key again, it will enter the
setting mode, after all the settings are finished, it will display zero reading.)
STEP 1: Step on the platform barefooted
when the LCD displays “0.0”.
STEP 3: Then the measuring results will be displayed: The difference in weight, Body
Fat, Total Body Water, Muscle Mass, Bone Mass and BMR three times. Then
display the personal profile you set once and turn off.
* If it fails to complete the analysis, the LCD will only display the weight data.
(To find out the solutions, please refer to Troubleshooting for more details.)
Daily Measurement
With original SENSE ON patent technology, Figure will switch on as you step on the
platform barefooted.
Stand still and keep full contact with the scale until the LCD stops displaying moving “o”.
STEP 2: Stand still and the weight data will be locked with the unit is displayed on the LCD.
Keep full contact with the electrodes until the LCD stops displaying moving “o”.
After the weight is locked, the system will automatically identify the possible User ID
with most similar history records.
If it identifies one user, it will skip the step about user selection, then display the difference
in weight, Body Fat, Total Body Water, Muscle Mass, Bone Mass and BMR data
sequentially three times. Then display the personal profile you set once and turn off.

sequentially three times. If you don’t choose the user, it will display the weight again and
then turn off automatically.
If there are no pieces of measuring results stored under a specific UserID, “” will
be displayed instead.
If it fails to identify the possible User ID, the LCD will only display the weight data
then shutdown.
(To find out the solutions, please refer to Troubleshooting for more details.)

Health Tips - About Body Fat
Fat is essential for human body. It can not only store energy and protect viscera, but also
regulate body temperature and maintain normal physiological function of human body.
However, too much body fat is harmful to human body. It is always accompanied by Fatty
Liver, diabetes, coronary heart disease, etc.
Therefore, self-measuring and self-monitoring body fat level are beneficial to your
health. Since we can’t judge body fat level simply by our weight, this body fat analyzer,
with BIA (Bio-impedance Analysis) technology applied, is an accurate device that offers a
quick and comfortable way to obtain your body fat level.

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (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.
NOTE 1 At 80MHz and 800MHz, the separation distancefor the higher frequency
range applies.
NOTE 2 These guidelines may not apply in all situations. Electromagnetic propagation
isaffected by absorption and reflection from structures, objects and people.
