How to use
1. Make sure the power supply is normal before using the smart health scale.
2. When a user stands barefoot on the smart health scale ( face the direction of smart health scale
display with each foot stepping on the ITO film of the smart health scale), once the body weight is
more than 5kg, the smart health scale will start measuring weight and body resistance and
display weight on the screen. The smart health scale will automatically turn off five seconds after
the user stepping off the scale.
3. When the smart health scale is on, switch weight unit (kg, lb, St) by pressing the Reset button
on the back of the scale .
4. When the smart health scale is off, press and hold the Reset button for 5 seconds or more, the
smart health scale enters configuration status, and then the user can bind smart health scale to the
app.

interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which
the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
To assure continued compliance, any changes or modifications not expressly approved
by the party responsible for compliance could void the user’s authority to operate
this equipment.
