PREPARATIONS BEFORE USE

Inserting the Batteries

Open the battery cover on the back of the measuring platform. Insert the supplied AA-batteries as
indicated.

Note: Be sure that the polarity of the batteries is set properly. If the batteries are incorrectly positioned the fluid

may leak and damage floors. If you do not intend to use this unit for a long period of time, it is advisable
to remove the batteries before storage.

Positioning the Monitor

Place the measuring platform on a hard, flat surface where there is minimal vibration to ensure safe and
accurate measurement.

Note: To avoid possible injury, do not step on the edge of the platform.

Handling Tips

This monitor is a precision instrument utilizing state-of-the-art technology. To keep the unit in the best
condition, follow these instructions carefully:

• Do not attempt to disassemble the measuring platform.

• Store the unit horizontally, and place it so that the Personal keys will not be pressed accidentally.

•Avoid excessive impact or vibration to the unit.

• Place the unit in an area free from direct sunlight, heating equipment, high humidity, or extreme
temperature change.

• Never submerge in water. Use alcohol to clean the electrodes and glass cleaner (applied to a cloth
first) to keep them shiny; avoid soaps.

Open as shown.

Tanita Body Fat Monitor/Scales allow you to measure your body fat percentage at home as easily as
you measure your weight.

What is Body Fat Percentage?

Body fat percentage is the percentage of fat in your body. Too much body fat has been linked to
conditions such as high blood pressure, heart disease, diabetes, cancer, and other disabling
conditions.

The BIA Method

Tanita Body Fat Monitor/Scales use the BIA (Bioelectrical Impedance Analysis) technique. In this
method, a safe, low-level electrical signal is passed through the body. It is difficult for the signal to
flow through fat in the human body, but easy to flow through moisture in the muscle and other body
tissues. The difficulty with which a signal flows through a substance is called impedance. So the
more resistance, or impedance, the signal encounters, the higher the body fat reading.

Body Fat Percentage Fluctuations in a Day

Hydration levels in the body may affect body fat readings. Readings are usually highest in the early
waking hours, since the body tends to be dehydrated after a long night’s sleep. For the most
accurate reading, a person should take a body fat percentage reading at a consistent time of day
under consistent conditions.

Besides this basic cycle of fluctuations in the daily body fat readings, variations may be caused by
hydration changes in the body due to eating, drinking, menstruation, illness, exercising, and
bathing. Daily body fat readings are unique to each person, and depend upon one’s lifestyle, job
and activities.

The graph on the left shows an example of daily body fat percentage fluctuations.

PRINCIPLES OF ESTIMATING BODY FAT PERCENTAGE

HOW TO MEASURE BODY FAT PERCENTAGE

Setting and Storing Data in Memory

The body fat monitoring function can be operated only if data has been pre-programmed into the unit.

1. Turn on the Power

Press the Set button to turn on the unit (once programmed, tapping a Personal Key turns on the
unit.) The unit will beep to confirm activation, the Personal Key numbers (1, 2, 3, 4) will be
displayed, an arrow icon will appear in the upper right corner, and the display will flash.

Note: If you don’t operate the unit for sixty seconds after the unit has been turned on, the unit will turn off

automatically.

2. Select a Personal Key Number

Press the Up button to select a Personal Key (pressing once will activate key number 1, pressing twice
will activate key number 2, etc.). Once you reach the Personal Key number you wish to use, press the
Set button. (During programming, the unit will beep once each time you press the Set button.)

3. Set Age

The display defaults to Age 30 (range of user age is between 7-99). Arrow icon appears in the
upper left corner to indicate Age setting. Use the Up/Down buttons to scroll through numbers.
When you reach your age, press the Set button. The unit will beep once to confirm.

4. Select Female or Male

Use the Up/Down buttons to scroll through Female ( ) or Male ( ), Female/Athlete and
Male/Athlete settings, then press the Set button. The unit will beep once to confirm.

5. Specify the Height

The display defaults to 5’ 7.0” (170cm) (range of user is from 3’ 4.0” – 7’ 3.0” or 100cm – 220cm).
Use the Up/Down buttons to specify Height and then press the Set button. The unit will beep once
to confirm.

6. Select Activity Level

To use the DCI (Daily Calorie Intake) feature properly, you need to set the Activity Level. Use the Up
button to specify Activity Level. Press the Set button to confirm.

Level 1 = Inactive lifestyles (little or no exercise)
Level 2 = Moderately active lifestyles (occasional, low intensity exercise)
Level 3 = Active lifestyles (exercise regularly)
Level 4 = Adult involved in intense physical activity (see p.1. for Tanita’s definition of Athlete)

Note: If the Personal Key is set in Athlete Mode, it will automatically set the Activity Level to Level 4.

The unit will beep twice and the display will flash all data (Male/Female, Athlete or Standard Adult,
Age, Height, and Activity Level) three times to confirm the programming. The power will then shut
down automatically.

Note: As you enter data or while the display flashes
the personal settings, check for mistakes, such as an
incorrect height setting, etc. If you find that you have
made a mistake, tap the Weight-Only Key while the
display is flashing. The unit will automatically shut
off and cancel any data that you entered at that time.

Note: [/] will appear in the upper right hand
corner indicating when the Up/Down buttons should
be used during programming.

USEFUL FEATURES

•Tanita Body Fat Monitor/Scales allow you to measure both weight and body fat percentage
simultaneously and easily, simply by stepping on a scale.

•Your Body Fat Monitor/Scale can be set for Children (age 7-17), Athlete or Standard Adults,
Male or Female, increasing the accuracy of the measurements.

• Personal data (Female/Male, Athlete/Standard Adult, Age, Height, Activity Level) can be pre-set
and stored in memory for up to four people.

• The BF-558 includes a Recall feature that compares your previous weight reading to the current
one being taken and displays the difference to help you track your results.

• The BF-559’s Recall feature compares both your previous body weight and body fat percentage to
the current readings.

• Healthy Range Indicator automatically displays where your body fat percentage falls within the
Body Fat Ranges chart (p.2).

• Daily Calorie Intake (DCI) is an estimate of how many calories you can consume within the next
24 hours to manage your current weight.

• Guest feature allows you to take readings without reprogramming one of the Personal keys.

•Weight-only Key provides quick weight readings.

• The unit emits a helpful “beep” when activated, and also at various stages in the programming
and measuring process. Listen for these sounds which will prompt you to step on the unit, look
at your readings, or confirm a setting.

Switching the Weight Mode

Your Body Fat Monitor/Scale can measure weight in three different modes: st-lb (British stone­pounds), kg (kilograms), or lb (pounds). The default setting (the setting at which Tanita products
are shipped) is st-lb. If you would like to change that setting, or if at any point another setting has
been inadvertently entered, follow these steps:

Press the Set and Up buttons simultaneously. Release the buttons, the display will flash. Press the
Up button to cycle through each weight mode until just the mode that you require is displayed.
Then press the Set button. The unit will beep twice in short succession, and the display screen will
flash to confirm your selection and store it in memory.

Note:If weight mode is set to pounds or stone-pounds, the height programming mode will be automatically

set to feet and inches. Similarly, if kilograms is selected, height will be automatically set to
centimetres.

Automatic Shut-Down Function

The automatic shut-down function shuts off the power automatically in the following cases:

• If you interrupt the measurement process. The power will shut down automatically within 10 to
20 seconds, depending upon the type of operation.

• If an extraordinary weight is applied to the platform.

• If you make a mistake during measurement or a key or button operation.

• During programming, if you do not touch any of the keys or buttons within 60 seconds.

•After you have completed the measuring process.

Note: If the power shuts off automatically, repeat the steps from “Setting and Storing Data in Memory” (p.5).

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.

Under Healthy Over Obese

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.

GB

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.

TROUBLESHOOTING

If the following problems occur…then…

“Lo” appears on the display, or all data appears and
immediately disappears.

Batteries are low. Replace batteries immediately.

The display shows “-----“ and goes off when a Personal Key is
pressed.

No data (Adult/Child/Athlete, Male/Female, Age, Height, Activity Level, Athlete/Standard Adult) has been
stored in the memory for that key. Pre-programme with personal data (p.5).

The display reads “Error” or “-----“ appears or the power shuts
off while measuring.

Be sure that you have selected the correct user mode (Male/Female, Age, Height, Activity Level,
Athlete/Standard Adult). Make sure socks or stockings are removed, and the soles of your feet are clean
and properly aligned with the guides on the measuring platform. Consider whether or not you have
selected the correct Personal Key and make sure that you wait for “0.0” to appear before stepping on the
platform. Step off and repeat steps on p.6.

“E1” appears while measuring.

Reading cannot be obtained if the weight capacity (21st 6lb/136 kg/300lb) is exceeded, or the weight
difference values detected are more than the unit’s limit value (+/- 9st 0.0lb, +/- 57.0kg or +/- 126.0lb).

Note: If body fat percentage is more than 75%, readings cannot be obtained from the unit.

The body fat percentage measurement does not appear after the
weight is measured.

Vibration will interfere with measurement of the fat percentage. Be sure to stand erect and still on the
measuring platform. Do not bend your knees. Be sure that shoes and socks are removed and check
foot alignment. Step off and repeat steps on p.6.

REPLACING THE BATTERIES

When the batteries run low, the “Lo” message will appear on the display window. When this message
appears, be sure to replace the batteries immediately, since weak batteries will affect the accuracy of
your measurements. Change all the batteries at the same time with new AA-size batteries. The unit
comes with trial batteries – their service life may be short.

Note: Your settings will not be erased from the memory when you remove the batteries.
