Battery Notes

• Always purchase the correct size and grade of battery most suitable for the intended use.
• Replace all batteries of a set at the same time.
• Do not mix old and new batteries. Do not mix alkaline and standard (carbon-zinc) batteries. Do
not use rechargeable (Ni-Cad, Ni-MH, etc.) batteries.
• Clean the battery contacts and those of the device prior to battery installation.
• Ensure the batteries are installed correctly with regard to polarity (+ and -).
• Remove screw to open battery cover and remove old batteries. Remove batteries from scale
that is not to be used for an extended period.
• "Lo" will appear on the display if battery is low and needs to be replaced. Remove and replace
batteries.
• When replacing the batteries, make sure you dispose of the old batteries in accordance with
applicable regulations. They should be disposed of in a location specifically designated for that
purpose so they can be re cycled safely and without posing any risk for the environment. Do
not burn or bury them.
Weight and Body Fat
How does it work?
While body fat can be measured in many ways, the method used in your scale is bioelectrical im-
pedance. This indirect method of determining body fat starts when a safe and very low electrical
current is sent through the lower half of the body. The electrical current flows more quickly through
water and muscle than it will through bone and fat. The scale measures the speed of the current.
Based on this number, the scale estimates body fat using a multi-step, mathematical formula.
Is it accurate?
Measurements of body fat tend to fluctuate a lot more than simple weighing, and different methods
of estimating body fat yield very different results. Just as different scales give different results, diffe-
rent body fat analyzers can provide very different body fat estimates. Even with the same scale the
numbers will vary because:
• Weight loss tends to produce substantial, continuous, and unpredictable changes in body water
content. Because body fat analysis is determined by water content in the body, results can vary
considerably from day to day.
• Hydration status affects body fat results. If you have just worked out, there is less water for the
electrical current to flow through. This may result in a higher body fat result. In the same way, if
you measure your body fat after drinking a lot of fluid, it may appear that body fat is lower than it
really is.
• Skin temperature can have an influence also. Measuring body fat in warm, humid weather when
skin is moist will yield a different result than if skin is cold and dry. As with weight, when your
goal is to change body composition it is better to track trends over time than to use individual
daily results.
• Results may not be accurate for persons under the age of 16, or persons with an elevated body
temperature, diabetes, or other health conditions.
What you need to know
• Percent body fat refers to the number of kilograms of fat divided by your total body weight and
multiplied by 100.
