Wearing Your Watch

All-day Wear and Exercise
For all-day wear when you’re not exercising, wear the device on your wrist horizontally, a ﬁnger’s width below your wrist bone and lying flat, the same way you would put on a watch.

Letsfit E22 Smart Watch-All-day Wear and Exercise A

For optimized heart rate tracking, keep these tips in mind:

Experiment with wearing the watch higher on your wrist during exercise. Because the blood flow in your arm increases the farther up you go, moving the watch up a couple of inches can improve the heart rate signal. Also, many exercises, such as bike riding or weight lifting, require you to bend your wrist frequently, which is more likely to interfere with the heart rate signal if the watch is lower on your wrist.
Do not wear your watch too tightly. A tight band restricts blood flow, potentially affecting the heart rate signal. This being said, the watch should also be slightly tighter (snug but not constricting) during exercise than during all-day wear.

Always consult your physician before beginning or modifying any exercise program.
The device, accessories, heart rate monitor, blood oxygen level measurement,,t 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 and blood oxygen levels.
If you have eczema, allergies,, or asthma, you may be more likely to experience skin irritation or allergies from a wearable device.
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 after not using your device, contact your doctor.

Prolonged rubbing and pressure may irritate the skin, so give your wrist a break by removing the band for an hour after extended wear.

Be sure your skin is dry before you put your bands back on.
Do not bring your device into contact with any sharp objects, as this could cause scratches and other damage.
For light-colored arm bands, minimize direct contact with dark-colored clothing, as color transfer can occur.

Troubleshooting Common Issues with the letsfit E22 Smart Watch

If you experience common problems such as syncing failures, inaccurate heart rate readings, or battery drain, several solutions can help restore optimal performance.

Wearing the watch slightly higher on the wrist can improve sensor accuracy during exercise.
