Advantages

1. BIA is a simple, quick, and non-invasive means of measuring body composition, making it particularly useful

for group screenings.

2. The Tanita BC-418 Body Composition Analyzer calculates “body fat ratio,” “body fat mass,” “fat free mass,”

“estimated muscle mass,” and “Base Metabolic Rate” using data derived by the DXA method using BIA.

3. Through the use of 8 electrodes, the BC-418 Body Composition Analyzer makes it possible to show separate

body composition mass for the right arm, the left arm, the trunk, the right leg and the left leg.



WARNING

• Individuals with a Pacemaker or Other Internal Medical Devices This equipment sends a weak electrical current through the body during measurement. Individuals who have internally implanted medical devices, such as Pacemakers, should not use this equipment due to the risk of malfunction to the device that may be caused by the weak electrical current.

• Inserting and Removing the Power Cord To reduce the risk of electric shock or product damage, never insert or remove the power cord with wet hands.

• Do not under any circumstances dismantle or alter the device, as this could result in electric shock or injury as well as adversely affect the precision of measurements.

• To prevent fire hazard Use only a correctly wired (100-240VAC) outlet, and do not use a multiple outlet extension cable.

• Measurements for physically disabled persons Physically disabled persons should not attempt to take measurements alone, but instead should have their caretakers assist them in using the device.



CAUTION

• Cross Contamination The Body Composition Analyzer should be used with bare feet. Please be sure to clean the scale platform with appropriate disinfectant after each use. Never pour any liquid directly on the scale platform, as it may leak and cause internal damage. Use a soft cloth and appropriate ethyl alcohol to wipe off platform. Do not wipe the platform with strong chemicals.

• Interpretation of Results The data provided by this machine, as well as any supplementary information such as diet or exercise programs based on this data, should be interpreted by a licensed professional.

• Please make sure you place the Weighing Platform on a level and stable surface. If the equipment is used when the Weighing Platform is unstable because not all feet are on the surface, there may be a risk of stumbling or inaccurate measurement. Never jump on the Weighing Platform, there may be a risk of stumbling and malfunction of the equipment.

• When handling printer unit, avoid any sharp edges.

• For the BC-418; Ensure you use the original AC adapter (MODEL: SA25-0535U). Using an AC adapter other than the original one may cause malfunction. Do not insert or remove the plug by the cable.



Maintenance

Since this equipment is accurately manufactured and adjusted, please observe the following instructions.

• Never disassemble the equipment as this may cause malfunction. Users must not disassemble or adjust this equipment. Please inspect the equipment in accordance with the regulations in your country.

• Unplug the unit from the wall outlet when it will not be in use for long periods of time.

• In order to reduce the risk of a short circuit, please keep any liquid or metal objects (paper clips, etc.) away from the printer.

• Keep the electrodes clean by wiping them with disinfectant.

• Do not drop the unit, and avoid locations with constant vibration.

• Do not put this equipment in direct sunlight, close to heaters or near direct draughts from air conditioners.

• When transferred to any location where there is a difference of more than 20 degrees centigrade (40 degrees Fahrenheit), wait 2 hours before using.

• When disposing of this unit, please do so in accordance with the prevailing regulations in each country.

General Instructions for Accurate Measurement

This equipment sends out a very weak electric current to measure impedance (electrical resistance) of the body. Therefore, in principle, users need to use this equipment with bare feet. Moreover, since impedance fluctuates in accordance with the distribution of body fluid, please observe the following instructions for accurate measurement.

• To prevent a possible discrepancy in measured values, avoid taking measurements after vigorous exercise until sufficiently

rested.

• To prevent inaccurately low body fat percentage measurements and other measurement errors, always hold both arms

straight down when taking measurements.

• As changes in body water and body temperature can have a major impact on measurements, measurements should be

made every day at the same time under similar conditions (always urinating before taking measurements, etc.) to get a more accurate picture of the measurements over time.

• Ensure that your arms are not touching your side and that the inner thighs are not touching each other during

measurements; if necessary, place a dry towel between your arm and side and/or between your thighs.

• Also, make sure the soles of feet are free of excess dirt, as this may also act as a barrier to the mild current.

• False results may be reported after excessive food /fluid intake, or after periods of intense exercise.

* For further details, see the Technical Notes on page 36.

• This equipment is designed for the majority of the population leading healthy lives with a regular lifestyle. For people

suffering from sickness, or whose lifestyle is very different from the norm, it is recommended that the data from this product should not be used as an absolute value, but rather as a reference to observe the rate change. * For further details, see the Technical Notes on page 36.

• Measurement is sometimes impossible on a surface that is strongly vibrating. In this case, please move the equipment onto

a surface with little vibration.

• Do not take measurements while using transmitters, such as mobile phones, which may affect readings.

Remove the Bottom Cover.

Insert the two cables from the column into the holes on

the Weighing Platform.

Tighten the four Column Attachment Screws and attach

the column to the Weighing Platform.

Connect the two cables from the column to the Weighing

Platform as shown in the illustration and replace the

Bottom Cover using the two Bottom

Cover Attachment Screws. When

replacing the Bottom Cover, please

place the cables in the right position

so that they will not get caught

 Connection and Installation

3.Preparation for Use

For accurate measurement, place the Weighing Platform on as flat a surface as possible and adjust the level with the adjustable feet so the bubble in

the level gauge is in the center of the frame.



CAUTION

Make sure you place the Weighing Platform on a stable level surface and adjust the level with the adjustable feet. If the Weighing Platform is not stable because not all the feet are on the surface, for example, there is a risk of stumbling or inaccurate measurement.

 Connection of Plugs

1. Insert the plug from the AC adapter into the DC jack on the back of the weighing platform.

2. Connect the cable and the AC adapter and insert the plug on the cable into the wall outlet.



WARNING

•To avoid electric shock, do not insert or remove the plug with wet hands.

•To avoid electric shock, do not use the equipment near water.



CAUTION

•To avoid measurement error, do not measure while using equipment that generates radio waves, such as mobile phones.
