Charging the Watch
When using the watch for the first time, charge it fully first.
1. Connect the USB charging cable to a powered USB device.
2. Place the watch onto the charging case. Ensure the charging ports
of the watch and charging case touch each other. Close the case
cover tightly.
3. When your watch is charging properly, a small battery icon will be
visible on its screen. After charging, the battery icon will be in full
green.
• Charging with a powerbank or a portable charger is not
recommended.
• The watch cannot be used while charging.
For accurate reading, your watch should fit closely on your
wrist. The back of your watch should come in contact with
your skin for features like exercise and heart rate reading.
