Congratulations! You have purchased a precision health monitoring product that should provide you

up and use instructions carefully before using the scale.

General Operation

1.  Use 2 AAA batteries (included. Remove any plastic wrap from the  

batteries before proceeding). Always replace all batteries at the  
same time; do not combine old and new batteries. Do not mix  
Alkaline, carbon-zinc (standard) or Nickel-Cadmium  
(rechargeable) batteries.

2. Open the battery compartment on the bottom of the scale.
3.  Place the batteries into the battery compartment according to  

the “+” and “-” polarity symbols in the compartment. (figure 1)

4. Replace the battery compartment cover.
5.  Replace all the batteries if “LO“appears on the screen or if readings grow dim or irregular.

1.  The maximum capacity of this scale is 440 lbs / 200 kgs / 31 ST 6lbs. Should “O-Ld” appear 

on the display during a weighing, this indicates that the maximum weighing capacity of the 
scale has been exceeded. Remove the weight immediately; otherwise, permanent damage 
may occur.

1.  Install 2 AAA batteries (please read “Battery Installation” section  

of this manual for battery installation instructions).

2.  Your scale has been set at the factory to read weight in pounds.  

Select the weight unit wants among kg/lb/st. Button is located on  
the back of the scale. Press button to switch between  
kg/lb/st. (figure 2)

3.  Place scale on flat, hard surface. Carpeted or uneven floors may  

affect accuracy. (figure 3)

4.  Step on the scale (disregarding the reading) and step off. This  

process insures the scale is set and is now ready for use. Do  
this whenever the scale is moved. At all other times step  
straight onto the scale.

5.  Step onto the scale platform and remain still. The display will  

count up to your weight. The display will flash twice when the  
weight is locked. Your weight is now displayed.
