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 recreational purposes and 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 accepted for the consequences of any erroneous 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, blood oxygen, stress and calorie data.

wearing, and wait two to three days to see if your symptoms ease. If symptoms

irritation or allergy from a wearable device.
