CHARGING
This product is charged using a magnetic charging base. Please use the standard charging base
for charging. Align the charging port with the metal contacts on the charging base until the
charging level indicator appears on the watch screen.
Note:
Use the original charging base and ensure that the charging port is dry.
Connect the USB port to a computer USB port or a mobile phone charger with an output current
above 1A.
WEARING AND REPLACING THE STRAP
Wear the strap at a comfortable tightness to allow the skin to breathe and the sensor to function.
When measuring SpO₂ (blood oxygen saturation), avoid wearing the watch on the wrist joint,
keep your arm flat, maintain a comfortable (appropriately loose) distance between the watch and
the wrist skin, and keep your arm still throughout the measurement process. When affected by
external factors (such as arm sag, arm sway, arm hair, and tattoos), the measurement result may
be inaccurate or the measurement may fail and provide no output.
You can tighten the watch strap during workouts and loosen it afterwards. Tighten the strap
appropriately if your watch sways on your wrist or produces no data output.
To attach or detach the watch strap, see the illustration below.
Note:
Once the strap is attached, pull on the strap with appropriate force to ensure secure attachment.
Avoid contact with liquid, because the leather strap is not waterproof. Switch to a fluororubber or
silica gel strap when you cannot avoid contact with liquid, for example when swimming.
