UNDERSTANDING YOUR READINGS
PROGRAMMING THE GUEST MODE
Healthy Range Indicator (Standard Adults only*)
Your body fat monitor/scale automatically compares your body fat reading to the Healthy Body Fat
Range chart.
Following your body fat percentage reading, four black squares will appear along the bottom of the
display, identifying where you fall within the Body Fat Ranges for your age and gender, as well as telling
you where in that range your percentage falls (i.e. low, middle or high end). For example, if you are a
female, age 20-39 and your reading is 22.5%, the squares will appear above the Green (0) or Healthy
Range area, and the square on the left (or low) end will appear highlighted. For more about the Healthy
Range, see page 2. (Range of user age is between 20-79)
Yellow (-): Underfat; below the healthy body fat range. Increased risk for health problems.
Green (0): Healthy; within the healthy body fat percentage range for your age/gender.
Orange (+): Overfat; above the healthy range. Increased risk for health problems.
Red (++): Obese; high above the healthy body fat range. Greatly increased risk of obesity-
related health problems.
*Athletes may have a lower body fat range based on their particular sport or activity.
Daily Calorie Intake
Having pre-programmed your personal information, your body fat monitor/scale can estimate how many
calories you can consume within the next 24 hours to maintain your current weight.
Therefore, if you would like to lose weight, consume less calories than the amount shown.
Recall Feature
By automatically storing your results, the Recall feature can show you the difference between your
current reading and your previous one. This feature is potentially helpful to users on a diet and/or
exercise programme.
The Guest mode allows you to use the monitor without losing the information already assigned to a
Personal Key.
To programme the Guest mode, press the Down button marked with a “G”. An arrow points to Guest on
the display screen. Then follow steps 3 through 6 in “Setting and Storing Data” (p.5.) Next follow the
directions for “Taking Weight and Body Fat Readings” (p.7) from step 3 onward.

TAKING WEIGHT MEASUREMENT ONLY
Select Weight-Only Key
Using your toe, tap the Weight-only key. After 2 or 3 seconds, “0.0” will appear in the display and the
unit will beep. When “0.0” appears in the display, step onto the platform. The body weight value will
appear.
If you remain on the platform, the display will flash for about 30 seconds, and then the power will automatically turn
off. If you step off the platform, the weight will continue to show for about 5 seconds, then “0.0” will appear and the unit will
shut off automatically.

Getting Accurate Readings
To ensure accuracy, readings should be taken without clothing and under consistent conditions of
hydration. If you do not undress, always remove your socks or stockings, and be sure the soles of
your feet are clean before stepping on the measuring platform.
Be sure that your heels are correctly aligned with the electrodes on the measuring platform. Don’t
worry if your feet appear too large for the unit – accurate readings can still be obtained if your toes
overhang the platform.
It is best to take readings at the same time of day. Try to wait about three hours after rising, eating,
or hard exercise before taking measurements. While readings taken under other conditions may not
have the same absolute values, they are accurate for determining the percentage of change as long
as the readings are taken in a consistent manner. To monitor progress, compare weight and body
fat percentage taken under the same conditions over a period of time.
Note: An accurate reading will not be possible if the soles of your feet are not clean, or if your knees are bent
or you are in a sitting position.
After programming your personal data you are ready to take a reading.
Select Personal Key
Using your toe, tap your pre-programmed Personal key. (Release the key within 3 seconds or the
display will show “Error”.) The unit will beep and the display will show the programmed data. The
unit will beep again and the display will show “0.0”. Now step onto the platform.
Note: If you step onto the platform before “0.0” appears the display will show “Error” and you will not obtain
a reading. Furthermore, if you do not step onto the measuring platform within about 60 seconds after
“0.0” appears, the power is shut-off automatically.
Get Your Readings
Your weight will be shown first. Continue to stand erect on the platform. The numbers 5, 4, 3, 2, 1 will
appear on the display and fade away starting with 5. When 1 fades away, the display will show both your
weight and body fat percentage. The body fat range icons will flash alternately for a few seconds and
your body fat range will appear. The unit will then display a suggested DCI (Daily Calorie Intake) value.
BF-558: The Recall feature will automatically display the numerical difference between your current
weight reading and the previous one. For example, if your previous reading was 9st 4lb and you
lost one pound making your current weight 9st 3lb, the difference would be shown as -1lb.
BF-559: To use the Recall feature, press the Up button while the display is flashing alternately between
the weight/body fat and DCI readings. The Recall feature will then display the numerical difference
between your current weight and body fat readings and the previous ones. For example, if your
previous reading was 9st 4lb with 22.5% body fat and you lost one pound and 0.1% body fat, your
current reading would be 9st 3lb with 22.4% body fat, the difference would be shown as –1 lb/-0.1%.
This unit will store your results automatically to calculate the difference between the next reading
and the current one.

Note: Even if you step off the platform after all the
results are displayed, the alternating display of body
fat percentage and body weight will be repeated five
times. If you stay on the platform after all results are
displayed, the alternating display of body fat
percentage and body weight will be repeated for 30
seconds. The unit will then shut down automatically.
