Before Use
1.1 General Informaon
During measurement, this machine will send a low level
impercepble electrical current throughout the body.
Individuals with implanted medical products, such as:
Pacemakers.
ECG products.
Electronic lungs and other electronic medical life support equipment.
should not use this product, as the electric current may affect
the implanted product.
Warning
Disposal
All baeries contain toxic compounds; baeries should be disposed
of via designated competent organizaons. Baeries should not be
incinerated.
This product is not to be treated as regular household waste, but
should be taken to a designated collecon points for electronics.
Further informaon should be provided by local waste disposal
authories.
Usage of Results
The FTG-588 is not a diagnosc product.
BIA results are calculated based on impedance values validated
with representave populaon studies and stascal analysis.
As such, the technique is best suited for tracking progress for an
individual over a period of me, or for categorizing large groups of
people, rather than used as a one-me analysis. Accuracy of results
is highly dependent on proper measurement procedure.
Please follow instrucons carefully for best results.
Pregnant women should use the weight and heart rate funcon only.
Body composion calculaons may be of limited accuracy.

Before Use
1.2 Connecng to o'Care app on smartphone

The FTG-588 is designed to be used with the o'Care smartphone app,
making it easy to track body composion results for as many users as
needed.
An iOS or Android device (with operaonal Bluetooth and Wi-Fi) is
required to download the o'Care app, and retrieve measurement
results from the product.
Aer installaon, product and app is ready for use. Create a user profile
as instructed by o'Care. The FTG-588 will automacally pair and sync
with your smartphone if the o'Care app is open during measurement.

3.3 Measurement Results Explained
Body fat percentage is useful in determining the specific cause of weight
loss or gain. Average percentages differ according to specified groups and
categories, most significantly by gender. Although no universally accepted
published ranges or cut-off points for body fat percentage currently exist,
it is sll an important value in assessing change in body composion and
health.
Body Fat Percentage
Basal metabolic rate is the minimum required energy to sustain the body's
vital funcons while at rest. These funcons include breathing, blood
circulaon, regulaon of body temperature, cell growth, brain funcon,
and nerve funcon. BMR tends to decrease with age or reducon in weight,
and is posively correlated with increase in muscle.
Basal Metabolic Rate (BMR)
BMI is a commonly used index by the World Health Organizaon (WHO), ulizing
height and weight to classify underweight, normal, over, and obesity in adults.

Abdominal fat can be divided into visceral and subcutaneous fat. Visceral
obesity can occur even if your weight or BMI is within normal standards.
It's possible to be thin on the outside, but fat on the inside . Visceral fat
level has high correlaon with risk of a variety of obesity-related diseases.

Your calculated metabolism is compared to average BMR for your age and gender group.
Body Age
Higher bone mineral content may be an indicator of higher bone density.
Bone Mineral Mass
Increase in muscle mass increases BMR, which in turn allows the body to
burn calories more quickly.

Body water refers to the water contained in the ssues, blood, bones, and
elsewhere. Body water in a healthy (non-obese) adult can fluctuate by
roughly 5% daily, influenced by physiological acvity and consumpon of
food and drink . Due to larger size and muscle mass, healthy adult men
tend to have more body water than women (on average) .
Body Water
Typically, children have a higher percentage of body water than adults,
and body water levels reportedly decrease further around middle age as
part of the aging process . In addion, various diseases can affect body
water percentage .Therefore, BIA esmaons should be used with
parcular cauon if subject's body water differs significantly from
the representave populaons used to formulate BIA algorithms.

3.4 About Bioelectrical Impedance Measurement
14
The FTG-588 uses Bioelectrical Impedance Analysis (BIA)
to calculate body composion. At its core, BIA operates
by treang the human body as an electrical conductor with
in an alternang current circuit, from which the alternang
current resistance and impedance is measured.
The measurement current flows from one lower limb through the lower
abdomen and then into the other lower limb, and the bioelectrical
impedance is measured. For reference, the impedance measurement
methods for the legs are shown in the diagram.
Impedance
Using a combinaon of exisng populaon data and in-house research,
body composion analysis formulas can calculate results based on the
Impedance, Height, Gender, Age, and Weight of the subject.
These algorithms are formulated with reference to "gold standard"
measurements such as Dual-Energy X-ray Absorpometry (DXA) to
confirm viability and accuracy.
1.Do not exercise or perform strenuous physical tasks before measurement.
Strenuous physical tasks and exercise can result in a temporary change in
body composion measurements. As BIA analyzes electrical impedance in
the body, acvies that might affect impedance (e.g. increased
perspiraon, dehydraon, blood circulaon) may affect measurement
accuracy.

Before measurement, please take note of the following:
For best results, body composion analysis via BIA should be conducted
under specific condions. Inconsistent measuring condions will affect the
accuracy and validity of BIA results, and interpretaon of body composion.
The informaon below regarding the effect of various factors on measurement
results is largely sourced from related research by Kushner et al .

How to Use
3.4 About Bioelectrical Impedance Measurement
2. Affect of food and drink on measurement results.
Ingeson of food and drink can affect impedance and weight, and thus
analysis results. This change generally lasts 2-5 hours aer each meal.
For most accurate results, BIA measurements should ideally be
conducted in a fasng state (e.g. before breakfast) .
7. Measure height accurately.
Inaccurate height input will affect esmaon of body composion.
8. Perform the measurement in the morning.
As a general rule, BIA measurements should be performed in the morning to
minimize the influence of acvity throughout the day on measurements .
3. Do not shower or bathe directly before measurement.
Perspiraon can result in a temporary change in body composion
measurements, as the accuracy of BIA depends largely upon interpretaon
of measured impedance values, which are affected greatly by hydraon levels.
4. Perform the measurement under normal temperature condions (24-28°C)
Extreme temperatures (both hot and cold) can result in temporary
physiological changes. For example, excessive sweang due to heat
can cause increased impedance measurements, resulng in a higher fat
calculaon. For best results, measurements should be conducted in an
environment between 24-28°C.
5. Remove shoes and socks before measurement.
Shoes and socks will interfere with the electric current,
making measurement inaccurate or in some cases, impossible.
6. Avoid physical contact with other people during measurement.
Because BIA measures the impedance encountered as the electric
current travels through the subject's body, if another individual is touching
the subject, the electric current may pass through the other individual,
causing inaccuracy in measurement results.
