The Fat Loss Monitor is an excellent tool to quickly measure your body fat
percentage and body mass. Input your personal data. The monitor displays your
estimated value of body fat percentage using the Bioelectrical Impedance
Method, and indicates your body mass index in four ranges, low, normal, high
and very high. This is important information you need know to monitor your
weight loss or maintenance program.
Your HBF-306C comes with the following components:
• Unit
• Instruction Manual
• 2 “AAA” Batteries
Read all the information in the instruction book before using the unit.
WARNING!
This monitor cannot be used with a pacemaker or other implanted devices.
Consult the manufacturer of the implant device and your physician before
using this monitor.

Body
Weight
The Fat Loss Monitor displays the estimated value of body fat percentage by the
Bioelectrical Impedance (BI) method and indicates the Body Mass Index (BMI)
range with the BMI classification bar.
Bioelectrical Impedance Method
Muscles, blood vessels and bones are body tissues having
a high water content that conduct electricity easily.
Body fat tissue has lower electric conductivity.
The Fat Loss Monitor sends an extremely low-level
electrical current of 50 kHz and 500 µA through your
body to determine the amount of fat tissue. This weak
electrical current is safe and not felt while operating
the Fat Loss Monitor.
Body Fat Percentage
Body fat percentage refers to the amount of body fat mass as part of the total body
weight described as a percentage.
Body fat percentage (%) =
(Body Fat Mass in Pounds / Body Weight in Pounds) x 100
centage
Estimated Body Fat P
Hydrodensitometry, or underwater weighing, has been the established method for accurate
evaluation of body composition. Omron has used research information from several
hundred people using the underwater method to develop the formula by which the Fat
Loss Monitor works.The body fat mass and body fat percent is calculated by a formula
that includes five factors: electric resistance, height, weight, age, and gender.
er
Body Mass Index (BMI)
BMI is an internationally used index to show body composition by determining the
balance between the height and the weight.
Body Mass Index (BMI) Formula
US - Calculated using pounds and inches with this equation:
(weight in pounds x 703) / height in inches / height in inches
Metric – Calculated using kilograms and meters:
weight in kilograms / height in meters / height in meters

Understanding the normal changes in your body fat percentage can help you in preventing
or reducing obesity. Being aware of the times when the body fat percentages shift within
your own daily schedule will assist you in obtaining an accurate trending of your body
fat. It is recommended to use the Fat Loss Monitor in the same environment and daily
circumstances for each measurement. (See chart)

If a measurement is made under the following ph

percentage may differ significantly from the actual one because the water content in the
body is changing:
• After drinking a large amount of water or after a meal (1 to 2 hours)
• After drinking alcohol
• Immediately after vigorous exercise
• Immediately after a bath or sauna

CALCULATE YOUR FIT INDEX
The Fat Loss Monitor can be set to either NORMAL or ATHLETE mode.
Body composition varies based on your FIT Index.
Calculate your FIT index by using the following formula.
FIT Index = Frequency x Intensity x Time
Based on your FIT Index use the following mode when setting your personal data.
NORMALFIT Index < 60
ATHLETEFIT Index ≥60
EXAMPLE: Running 5 times a week for 30 minutes.
