Safety Information
General Use
• Check the scale before using. Do not use the
scale if it is damaged in any way.
• Do not strike or bang on the scale, and do not
use the scale if there is a slight crack in the glass.
Due to the nature of tempered glass, the glass
will shatter if there is a slight crack. If you see a
crack, contact Customer Service (page 30).
Please read and follow all instructions and safety guidelines in this manual.
NOTE:
• This scale should not be used to diagnose or treat
any medical condition.
• Scale data should not be used as a substitute for
medical advice from a healthcare professional.
• This scale uses a harmless electrical current to
measure body fat. We do not recommend using
the scale if you use medical electronic equipment
such as a pacemaker. Consult a healthcare
professional before use.
• The glass platform is slippery when wet. Always
make sure the platform and your feet are dry
before stepping onto the scale.
• Place the scale on a hard, flat surface to avoid
tipping.
• To weigh safely and accurately, stand with your
feet shoulder-width apart while on the scale. Do
not stand on the edge of the scale or jump on the
scale.
• Avoid standing on the scale for a long period of
time.
• Do not overload the scale. Maximum weight
capacity is 400 lb (180 kg).
• Keep the scale in a cool area with low humidity.
Keep the scale away from heat sources, such as
ovens or heaters. Store the scale horizontally, not
vertically.
• Not intended for commercial use. Household use
only.
