Why should the wristband be worn more tightly when measuring heart
rate?
The wristband uses light reflection principle, penetrates the skin through the light
source and collects the signal reflected to the sensor to calculate your heart rate. If you
don’t wear it tightly, there will be ambient light reaching into the sensor, which will affect
measurement accuracy.
Is the wristband waterproof?
The device supports IP67 certification standard. It means that you can immerse device
for 30 minutes into one-meter depth. Practically, it means that this device shall
withstand light rain or washing hands. Device with this certification is not waterproof in
streams of water, against high pressure or high-temperature water.
Does the Bluetooth connection need to be opened all the time? Is there any
data after disconnection?
Before the data is synchronized, the data is kept on the wristband host (seven days of
data can be retained). When the Bluetooth connection of the wristband and the mobile
phone is successful, the wristband data will be automatically uploaded to the mobile
phone. Please synchronize data to the mobile phone on a regular basis.
