QUICK START GUIDE
IMPORTANT: This scale uses BIA (Bioelectrical Impedance Analysis) to determine body fat
level, BIA sends a harmless signal through the body. It is NOT intended for children or
pregnant women, do NOT use this product anyone with an implanted medical device (such
as a pacemaker, metal plates or screws; or contraceptive devices). When in doubt, contact
your physician.
1. Remove the battery insulating strip before first use.
2. Place the scale on a hard flat surface. Avoid carpets, rug or soft, uneven surface.
3. If you would use the scale as a Weight-Only scale, for the first time to use the scale, you
may just step onto the scale to turn it on, and then step off, wait the screen to display “0.0”
and turn off, and then step on again, the screen will display your weight.
The information provided by this device is NOT meant to treat, cure, or prevent any disease
or illness. This device should NOT be used by anyone who is acutely or chronically ill,
suffering from a disease, or taking medications that affect your water levels. The accuracy
of readings for these patients has not been verified. Specific medical advice should be
obtained from a physician.
Statement of Accuracy
4. If you would use the scale as a Body Fat scale, remove socks and wipe your feet with a
damp cloth, leaving them slightly damp.
5. Press “SET” to enter Setup Mode. The Profile Number will flash on the screen. Press the
Up / Down arrow keys
and press “SET” to select a profile number.
6. Next, select your Gender.
• This device is intended for home / consumer use; it is not intended for professional use in
hospitals or medical facilities.
• Do not use the scale on a carpet, rug or uneven surface as these can cause inaccurate
results.
• This scale uses BIA (Bioelectrical Impedance Analysis) to determine body fat percentage.
BIA is considered reasonably accurate for measuring groups, or for tracking body
composition in an individual over a period of time, but is not considered sufficiently
accurate for recording of single measurements of individuals.
• As BIA is based on body water balance, your state of hydration can impact the level of
accuracy. Overall the BIA provides an inexpensive, reliable way to estimate and track
body fat level.
7. Next, set your Height.
8. Next, set your Age.
• For the most consistent and accuracy results, please do not measure within 30 minutes
after a meal or 120 minutes after an exercise. It is recommended that you measure at
the same time of the day, preferably early evening before a meal.
9. After entering your Age, the scale screen will display “0.0”. Please immediately step onto
the scale before it turns off and remain your body still. The scale will save your weight
in your profile, and then display your body fat, water, muscle, and bone ratios, which you
can write down to track. You do not have to remain standing on the scale, it will turn off
automatically. You may click the “UNIT” button located on the back of the scale to switch
display unit between Kilograms (kg) and Pounds (lb).
• Do not compare weight readings from one scale to another as some differences will exist
due to manufacturing tolerances.
Next time when you stand on the scale, it will identify your profile automatically according to
its stored weight information.
SPECIFICATIONS/FEATURES
• Do not use your Doctor's scale reading as "accurate" reference to determine the accuracy
of your scale, as it is not the right way to test the scale accuracy. The best way test scale
accuracy would be using 50 kg+ (110 lb+) standard Olympic weight bars on the scale.
• It should be used in a consistent manner for the most accurate readings. While readings
of this monitor might be different than that of other scales (hydro-densitometry or hand
held calipers), your changes in body fat percentage shown by this scale will be reflected
accurately.
• If you weigh yourself twice and get two different results, your weight lies between the two
readings.
SCREEN/LEGEND
• Measures weight, body mass index (BMI), body fat, body water, muscle and bone mass
• Uses Bioelectrical Impedance Analysis (BIA) technology to estimate body fat, total body
water percentage, bone mass, and muscle mass in generally healthy adult (18 years of
age or older).

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 Surpahs® DS2 Body Fat
Scale, with BIA (Bio-impedance Analysis) technology applied, is an accurate device that
offers a quick and comfortable way to obtain your body fat level.
This Surpahs® DS2 Body Fat Scale uses Bio Impedance Analysis (BIA) technology which
passes a small electrical current through the body to estimate body fat mass, total body
water, muscle mass, and bone mass. The electrical current is very small and may not be
felt. Contact is made with the body via four stainless steel pads on scale.
BATTERY
SETUP USER PROFILE
• Uses 4 x AAA batteries
• Make sure the + and – sides of the batteries are aligned correctly.
• Replace batteries when the low battery indicator “Lo” is shown.
If you would use the scale as Weight-Only scale, you may skip this section and refer to the
instructions in “USING THE SCALE AS WEIGHT-ONLY SCALE” section.
You are recommended to setup your profile before the first use, as this eliminates the needs to
enter it again for each time you take a measurement.
When batteries are inserted, the screen will display “8888”.
This scale can store up to 4 user profiles (identified as P1 to P4) in memory.
1. Remove socks and wipe your feet with a damp cloth, leaving them slightly damp.

6.After entering your Age, the scale screen will display “0.0”. Please immediately step onto
the scale before it turns off and remain your body still. The scale will save your weight
in your selected profile, and then display your Body Fat, Total Body Water, Muscle Mass,
Bone Mass, Kcal and Weight.
3. The scale will switch off and now is ready to use.
This completes the programming of your profile. The next time you use your scale, it will
identify your profile by comparing your current weight with the stored weight.
4.Wipe your feet with a damp cloth, leaving them slightly damp, step onto the scale to turn it on.
Note: If your weight changes by +/-2 kg (+/-4.4lb) or more, the scale may have trouble
identifying your profile. It is recommended that you re-configure your profile.
USING THE SCALE AS WEIGHT-ONLY SCALE
If you just need to measure body weight only, under this WEIGHT-ONLY mode, your
Surpahs® Body Fat Scale will operate as a conventional weight-reading scale, there
are no special programming steps are required.
5.Stand still and keep fully contact with the 4 stainless steel electrodes until the screen stop
displaying the moving “o”.
Once the scale is initialized, as previously described, you may simply step on the scale
to turn it on and measure your current weight only.

1. Place the scale on a flat, hard surface. Carpeted or uneven floors may affect accuracy.
2. Step onto the scale platform and remain still while the scale computes your weight.
3. The scale displays your weight.
4. The scale will automatically turn off in about 10 seconds if there is no operation.
6.It automatically identifies a programmed profile (P1-P4). And then displays your Body Fat,
Total Body Water, Muscle Mass, Bone Mass, Kcal and Weight two times in sequence. You
can write down to track. You do not have to remain standing on the scale, it will turn off
automatically.
USING THE SCALE AS BODY FAT SCALE
1.If you haven’t programmed a user profile, please follow the instructions in “SETUP USER
PROFILE” section to complete the setup.
2.If it is the first time use or has been moved from one place to another, please follow the
instructions in “INITIALIZATION/ CALIBRATION” to initiate the scale.
3.For the most consistent and accuracy results, please measure at the same time of the day,
and do not measure within 30 minutes after a meal or 120 minutes after an exercise.
NOTE:
If your weight changes by +/-2 kg (+/-4.4lb) or more, the scale may have trouble identifying
your profile. It is recommended that you re-configure your profile.
2. It is recommended to measure body fat and weight daily at the same.
3. Use this product without clothing for best accuracy. Clothes can vary in weight and affect the
calculation.
4. Feet must be bare and clean. For best results, they should also be slightly damp.
If one or more other user’s stored weight is within +/-2kg (+/-4.4lb) of your weight, the scale is
unable to determine which one is your profile, and it will display a choice of profile numbers ,
you can then use the Up / Down arrow keys to confirm the correct profile. Upon confirming, it
will display the results two times in sequence. If no profile is confirmed, it will automatically
turn off after a few seconds.
Press (▲ ) to ch oose P1

Body water measurement results are influenced by the proportion of body fat and muscle. If the
proportion of body fat is high, or the proportion of muscle is low, then the body water results will
tend to below.
It is important to remember that measurements such as body weight, body fat and body water
are tools for you to use as part of your healthy lifestyle. Since short term fluctuations can be
normal, we suggest that you chart your progress over time, rather than focus on just a single
day’s reading. Consult your physician to determine what is most ideal for you.

MUSCLE MASS
MAINTENANCE AND CARE
Muscle mass is important in determining a healthy body composition. A person with a higher
% of muscle mass finds it easier to move, but needs more energy to do it. Exercise is very
important in maintaining a healthy body and the muscle mass % is a useful indicator to control
it. The normal muscle mass percentage on the body weight lies between 38% and 54% for
men and between 28% and 39% for women depending on age and physical activity level.
