Syncing Bluetooth
Simply step on the scale to begin syncing with the WW app. 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).
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).
If you get an error reading, make sure you are stepping
on the scale in bare feet (no stockings or pantyhose)
and your feet are aligned on the metal strips. 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 “0.0” appears or if your
feet are not aligned on the electrodes, the scale will not
function properly.
We’re So Happy You’re Here!
The WeightWatchers program is designed to help you reach and
maintain your weight-loss goals. And your new body composition
scale can ramp up your results: research shows that people who
track their weight more frequently lose more weight.*
So let’s get you set up. Scan the QR code to connect your scale to
the WeightWatchers app.
A few reminders as you begin your journey:
• Track for better results
Tracking is the biggest predictor of success, because it builds awareness of habits that
help (or hinder) your progress. The WW app has tools for tracking food, activity, hydration,
sleep, body composition, and, of course, weight. Remember to sync your new scale to
the WW app—it’ll auto-track for you.
• Stay supported, 24/7

• Embrace non-scale victories
Your weight is just one number that matters. That’s why this scale measures body fat,
body water, muscle mass, and bone mass—which, science says, are also key for overall
health. Remember to also acknowledge (and celebrate!) your non-scale victories. Eating
veggies? Clothes fitting looser? Have more energy? These wins all count.
We can’t wait to see you succeed.

Other measurements
In addition to weight, your scale provides information about other measurements that
might be of interest to you: body fat, BMI, muscle, water, and bone mass. Read on
for a brief introduction to these factors. Please visit [insert link to landing page] for
more information about interpreting specific measurements.
Body fat
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.
Measurements of body fat tend to fluctuate more than weight. And just as different
scales can report different weights, different body fat analyzers can provide different
body fat estimates. Even with the same scale, the numbers can vary day to day
based on factors such as these:
• The amount of water in the body.
– Since weight loss leads to changes in the amount of water in your body,
results can vary considerably from day to day.
– 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.
– Similarly, 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.
– Measuring body fat in warm, humid weather when skin is moist will yield a
different result than if skin is cold and dry.
• Age, body temperature, and health conditions
– Results may not be accurate for persons under the age of 16, or persons with
an elevated body temperature, diabetes or other health conditions.
As with weight, when your goal is to change body composition, it is best to measure
at the same time and way every day and to review and learn from trends over time
rather than draw conclusions from the result on any one day.
BMI
Every time your body analysis monitor reads your weight and calculates your body
fat, it also calculates your Body Mass Index (BMI). BMI is a numerical value derived
from a mathematical formula using height and weight. It has been used by many
health, research, and government organizations to estimate population-level health
risks. Like weight, BMI is only one indicator of health and should be considered in
the context of a bigger picture of health indicators including physical fitness, blood
pressure, glucose control, and cholesterol levels.
Body water/hydration levels
Your hydration level is measured by using Bioelectric Impedance Analysis (BIA); the
same analysis used to calculate your body fat. Using your age and sex assigned at
birth, the percentage of water in your body is calculated. Staying sufficiently hydrated
can help improve your overall health and general feeling of well-being.
Do not take hydration measurements in situations such as: directly following exercise,
after drinking a glass of water, or during or shortly after menstrual cycles. Hydration
may not be at typical levels during these times.
Weight
Scales are the best tool for monitoring weight and weight loss. A scale measures your
total body weight, which includes bone, muscle, fat, and water. While your weight is
important, it is only one indicator of overall health. For example, two women with the
same height and weight can have very different levels of fat and muscle and different
health profiles.
When your goal is to lose or maintain weight, it is best to review and learn from the
trends you see over time rather than draw conclusions from what the scale says on
any one day. This is because body weight can fluctuate from hour to hour and from
day to day due to a variety of factors such as:
• How much sodium (salt) you have eaten
• How large or small your most recent meals were
• How hydrated you are — which can be influenced by exercise, illness, and
fluid intake
• Hormone levels and menstrual cycles
A healthy rate of weight loss is 1-2 pounds a week. But this is an average: it’s
important to know that weight loss does not occur in a straight line. Small weight
gains and losses, as well as plateaus, are common along the way as your body
adjusts to your new eating, activity, and other self-care habits. Therefore, weight
trends over time (e.g., weeks and months) are a more reliable predictor of progress
than what the scale says on any given day.
It’s also important to know that different scales often give slightly different results.
For example, the scale at your doctor’s office or WW Workshop may show one
weight, while your scale at home shows another. If you use different scales in different
circumstances, we recommend tracking your weight trends based on one scale only.
Recommendations for weighing yourself
WW recommends tracking your weight at least once a week and no more than once
a day. Research shows that people who track their weight consistently are more likely
to lose weight and keep it off; so aim to develop a habit around weight tracking by
doing it at the same time, in the same situation each day you do it. Here are a few
other tips:
• Keep your scale somewhere that you’ll see it each morning
• Weigh yourself first thing after you wake up. Do it after you have used the
bathroom and before you have had anything to eat or drink.
• Weigh yourself without clothes (ideally) or with light clothing and no shoes.
• Use the same scale each time you weigh yourself to track your progress
consistently
• Pay attention to your non-scale victories! Even when the scale doesn’t move the
way you’d like it to, the behavior changes you are making add up to move you
forward.
• Track your weight even if you think you gained. Research suggests that the more
consistently you maintain the habit of tracking your weight, the more likely it is that
you will make progress over time. Consistency is key!
