Before Using Scale
Precautions for Use
CAUTION! Use of this device by persons with any electrical implant such
as a heart pacemaker, or by pregnant women, is not recommended.
1. Remove all packaging materials.
2. Remove the isolator tab from the battery compartment – without opening the
battery cover at the bottom of the scale, gently pull out the isolator tab. (In case
the tab cannot be pulled out, or if the scale display does not work after you have
pulled the isolator tab, remove the screw from the battery cover and remove
the cover. Gently pull out the isolator tab or any pieces of it that may block the
battery contacts. Ensure the batteries are installed correctly. Replace the battery
cover and tighten the screw again.)
3. For best accuracy, place scale on tile or hardwood floor, rather than uneven,
flexible or soft flooring (such as carpet). Ensure that the floor surface is even.
Weight Measurement Only

Did you know?
• Your scale works as a body analysis monitor even without the app – you do not
need a smart device to check your weight, body fat, body water or BMI!
• But you will need a smart device to set goals, track your progress, earn badges,
and participate in other fun activities that are only available on the app.
• If you are a Weight Watchers member, your weight data will sync with your account
on the Weight Watchers app; no more need for manual data entries!
• If you use other health and fitness apps, and would like them to receive data from
your scale, the app will sync data to the Health app (Apple) and to the Google Fit
app (Android) and allow your favorite apps to pull your data from there.
• If you travel without your scale, you can monitor your weight on any other scale and
enter it manually into the app.
For more information on the scale, on how to set yourself up as a user without
the app, and about what your body analysis readings mean, please read this
instruction booklet.
Syncing Bluetooth
This is a Bluetooth enabled scale. It will try to broadcast a Bluetooth signal every
time it is being used, even if you are not using it with the app, or your smart device
is out of range. Generally, you will see the following in the scale display:
Bluetooth symbol blinking:
scale is trying to communicate with your
smart device
Bluetooth symbol stable and (check mark symbol):
Bluetooth
connection has been established
Bluetooth symbol stable and X:
pairing failed, no Bluetooth
connection, no data is being transmitted
Bluetooth symbol not visible:
scale is in manual mode, no Bluetooth
connection, no data is being transmitted.
If a Bluetooth connection cannot be established, the scale will still measure and
display all your data, as long as you are set up as a user on the scale
(read “Personal Data Setting Mode” next page).

After a few seconds, the LCD will show your body weight, body fat percentage, body
water percentage and BMI for several seconds, and then turn off automatically.
If you get an error reading, make sure you are stepping on
the scale in bare feet (no stockings or pantyhose). If you still
get an error reading, your skin may be too dry: Try rubbing
a bit of lotion on the soles of your feet and make sure not to
slip on the platform of the scale.
NOTE:
Your scale will also read error if your weight is below or above
the specifications for the scale.
Low battery warning: When the batteries are critically low,
the scale display will show “LO” and it is time to replace the
batteries (see battery replacement instructions).
NOTE:
If you step on the scale before “0.00” appears or if your
feet are not aligned on the electrodes (stainless steel metal
strips), the scale will not function properly.
Weight and Body Fat
How does it work?
While body fat can be measured in many ways, the method
used in your scale is bioelectrical impedance. This indirect method of determining
body fat starts when a safe and very low electrical current is sent through the lower
half of the body. The electrical current flows more quickly through water and muscle
than it will through bone and fat. The scale measures the speed of the current.
Based on this number, the scale estimates body fat using a multi-step, mathematical
formula.
Is it accurate?
Measurements of body fat tend to fluctuate a lot more than simple weighing, and
different methods of estimating body fat yield very different results. Just as different
scales give different results, different body fat analyzers can provide very different
body fat estimates. Even with the same scale the numbers will vary because:
• Weight loss tends to produce substantial, continuous, and unpredictable changes
in body water content. Because body fat analysis is determined by water content in
the body, results can vary considerably from day to day.
• Hydration status affects body fat results. If you’ve just worked out, there is less
water for the electrical current to flow through. This may result in a higher body fat
result. In the same way, if you measure your body fat after drinking a lot of fluid, it
may appear that body fat is lower than it really is.
• Skin temperature can have an influence also. Measuring body fat in warm, humid
The scale will now switch to Age setting mode.
Age will flash. Press the UP or DOWN button to choose the
age (10 to 100). Pressing and holding the UP or DOWN button
will advance numbers quickly. Press the SET button to confirm
the Age.
The scale will now enter the Gender setting mode.
Default icon will flash. Press the UP or DOWN button to
choose between female, and male. Press SET button to
confirm selection. The scale will display the user data for a
few seconds and then will enter into body analysis mode and
“0.00” will appear on the display.
Note 1:
If you need to edit any of your personal data, you can do so while the
data is being displayed: Simply press the SET button and scale will go back to the
Personal data setting mode again. Follow the instructions above.
Note 2:
In the Personal data setting mode, the scale will return to standby mode
automatically if no button is pressed within 15 seconds, and already entered data
will not be saved. If that happens, simply repeat the Personal data setting process
described above.
User Recognition
(when using scale without app)
After your initial setup on the scale, the scale will automatically recognize you (based
on your weight being within a certain range of your last measured weight) and display
your user number. User number will blink for a few seconds, then become stable. If
an incorrect user number is displayed (which could happen if the weight of another
user of the scale is very close to yours), you can adjust to the correct user number by
manually pushing the up/down arrows until the correct user number shows.
If the scale cannot establish a match with an existing user profile, the word “user” will
blink on the display. If you have a user number set up, you can manually enter it now
(push up/down arrows until your user number shows).
Body Analysis Measurement
(Using Scale Without App)
Operate the scale on a secure flat floor. Tap on the platform firmly to activate the scale.
Wait until you see “0.00” in kg mode or “0.0” in lb mode, then press the UP or DOWN
button to select your user number. Your data (height, age, gender) will quickly display
again.
The scale measures body mass using Bio Impedance Analysis. Once the LCD shows
"0.00", step on the scale barefoot, with your feet aligned on the electrodes (stainless
steel metal strips) on both sides of the platform. Note: You must be barefoot in order
for the scale to read your body analysis measurements. If your feet are not bare, the
scale will not be able to take your body analysis measurements and you will get an error
reading.
weather when skin is moist will yield a different result than if skin is cold and dry.
• As with weight, when your goal is to change body composition, it is better to track
trends over time than to use individual daily results.
• Results may not be accurate for persons under the age of 16, or persons with an
elevated body temperature, diabetes or other health conditions.
What you need to know!
• Percent body fat refers to the number of kilograms of fat divided by your total
body weight and multiplied by 100.
• During weight loss, percent body fat doesn’t appear to be reduced as quickly
as expected because total weight loss and total body fat are decreasing at the
same time (for a more detailed explanation, see next section).
• Weight loss in the form of body fat and lean tissue (muscle) is common, and
is normal.
• To minimize the loss of lean tissue, include regular physical activity, especially
strength training, in your weight-loss plan.
Why do I lose weight, but my body fat percentage doesn’t change much?
Remember that your Weight Watchers body fat monitor is showing your body fat as
a percentage, not as an absolute number of kilograms. At the beginning of a weight
loss program, a person may weigh 100 kg and show 30% body fat, equaling 30 kg
of fat (30% of 100 kg = 30 kg). A few weeks later, the same person may have lost a
substantial amount of weight. Weight is now at 90 kgs, yet body fat is still at 30%.
Why? Did that person not lose any fat? Yes, they did. At 90 kgs with 30% body fat,
the person now has 27 kgs of body fat (30% of 90 kgs = 27 kgs'), meaning that 3 kgs
of the total 10 kgs lost were fat. So, do not be overly concerned if your percentage
of body fat does not change despite the fact that you are losing weight. Remember,
to minimise the loss of lean tissue include regular physical activity, especially strength
training, in your weight loss plan.
BMI – What Is It?
BMI stands for Body Mass Index, a statistical term derived from height and weight.
It is closely linked to body fat and health outcomes. Over 50 organizations, including
the Australian & New Zealand Governments and the World Health Organization, have
adopted BMI guidelines. BMI is inversely related to fitness, meaning that the higher
your BMI, the less likely you are to be fit. Every time your body analysis monitor reads
your weight and calculates your body fat, it also calculates your BMI. Along with your
weight and your body fat measurements, the BMI reading gives you yet one more tool
to monitor your health and fitness.
Body water/hydration levels
General health standards indicate that one should consume approximately
2L. of water per day from food and liquids to maintain a healthy level of hydration.
Maintaining a good hydration level will help improve your overall health and general
feeling of well-being. If your hydration levels are lower than average, you should
increase your water intake accordingly.
Body water/hydration level – how is it measured?
The hydration level is measured by using Bioelectric Impedance Analysis (BIA).
The same analysis that is used to calculate your body fat is used to calculate your
hydration level. Taking into consideration a user’s age and gender, a calculation is
made that determines the percentage of water.
Please note:
It is not recommended to take the hydration measurements in certain
situations, such as following exercise, after drinking a glass of water, or directly prior
to, during or shortly after menstrual cycles. Hydration may not be at normal levels
during these times.
