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 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 of not using your device, contact your doctor.
• If you sweat for more than two hours while wearing your watch, be sure to clean and dry
  your band and your wrist to avoid skin irritation.
• Prolonged rubbing and pressure may irritate the skin, so give your wrist a break by removing the band for an hour after extended 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.
• Do NOT wash the watch with household cleanser. Please use soap less detergent, rinse thoroughly and wipe with a soft towel or napkin.
• While the watch is water resistant, wearing a wet band is not good for your skin.
• If your bands get wet—for example after sweating or showering—clean and dry them thoroughly before putting them back on your wrist.
• 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.

• Quick start guide

What’s in this document
This manual gets you started quickly with setting up your watch. Setup ensures that your watch can synchronize its data with the Lets fit app, where you can get detailed information on your stats, view historical trends, log sleep, and more. As soon as setup is complete, you’re ready to start moving. The remainder of the manual walks you through every function on your IW2, IW3.

Setting up Your Watch

Charging your watch
Please fully charge your watch before initial use.

1. Insert the USB plug of the charging cable into the USB port on your computer or a UL-certified USB wall charger.
2. Hold the other end of the charging cable near the port on the back of the watch until it attaches magnetically.
3. Make sure the pins on the charging cable lock securely with the port. The connection is secure when the watch vibrates and the battery icon with percent charged appears on the screen
   
   When the watch shows that the battery is low, connect the watch to a USB port with 5V-500mA. While the watch charges, there is a battery progress bar on the screen and you can check the battery level at any time.
4. Remove the watch from the power supply once fully charged.
   • USB charger requirement: DC USB port(5V-500mA)
   • Charging time: Approximately 2hours

Disassembling / Assembling Your Watch

Disassembly

1. Tore move the wristbands, turn over the watch and find the quick-release lever.
2. While pressing the quick-release lever inward, gently pull the wristband away from the watch to release it
   
   
3. Repeat on the other side.

Assembly

1. To reattach the wristbands, slide the pin (the side opposite the quick-release lever) into the notch on the watch. Attach the wristband with the clasp to the top of the watch.
   
2. While pressing the quick-release lever inward, slide the other end of the wristband into place.
   
3. When both ends of the pin are inserted, release the quick-release lever.

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.

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

1. 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.
   
2. . Do not wear your watch too tight. 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.

2. Set APP self-startup
3. Unrestricted background operation. The Android mobile phone installed with APP intelligently restricts the background operation by default, and App should be set manually without any restriction.

Why can’t take a hot bath with the smart bracelet?
Answer: the bath water has a relatively high temperature, and generates a lot of vapor which is in the gas phase with small molecular radius and can easily infiltrate into the smart bracelet from the shell gap. When the temperature drops down, the vapor will condensate into liquid-phase droplets which will easily cause the short circuit inside the smart bracelet and damage the circuit board and then damage the smart bracelet.
