Battery Warnings
A lithium-ion battery is used in this device. If these guidelines are not followed, batteries may
experience a shortened life span or may cause fire, chemical burn, electrolyte leakage, and/or
injury.
‐
Do NOT disassemble, modify, remanufacture, puncture or damage the device or batteries.
‐ Do NOT remove or attempt to remove the non-user-replaceable battery.
‐
Do NOT expose the device or batteries to fire, explosion, or other hazards.
Health Warnings
‐ If you have a pacemaker or other internal electronic device, consult your physician before
using a heart rate monitor.
‐ The optical wrist heart rate monitor emits green light and flashes occasionally. Consult
your physician if you have epilepsy or are sensitive to flashing lights.
‐ Always consult your physician before beginning or modifying any exercise program.
‐ The device, accessories, heart rate monitor, blood oxygen level measurement and related
data are intended to be used only for general fitness and wellness purposes, not for medical
purposes, and are not intended to diagnose, monitor, treat, cure, or prevent any disease or
condition.
‐
The heart rate and blood oxygen level readings are for reference only, and no responsibility is
assumed for the consequences of any false readings.
‐
While the optical wrist heart rate monitor technology typically provides the best estimate
of a user's heart rate, there are inherent limitations with the technology that may cause some
of the heart rate readings to be inaccurate under certain circumstances, including the user's
physical characteristics, fit of the device, and type and intensity of activity.
‐
The smart watch relies on sensors that track your movements and other metrics. The data
and information provided by these devices are intended to be a close estimation of your
activity and metrics tracked, but may not be completely accurate, including step, sleep,
distance, heart rate, and calorie data.
‐ If you have eczema, allergies or asthma, you may be more likely to experience skin
irritation or allergies from a wearabledevice.
‐ Whether you have the conditions above or not, if you start to experience any discomfort
or skin irritation on your wrist, remove your device. If symptoms persist longer than 2-3 days of
not using your device, contact yourdoctor.
‐ If you sweat for more than two hours while wearing your watch, be sure to clean and dry
your band and your wrist toavoid skin irritation.
‐ Prolonged rubbing and pressure may irritate the skin, so give your wrist a break by
removing the band for an hour afterextended wear.
Maintenance
‐ Regularly clean your wrist and the smart watch, especially after sweating during exercise
or being exposed to substances such as soap or detergent which may adhere to the internal
side of the watch.
