05. Battery Low
When the battery level drops to 10%, the Watch vibrates once and
shows a pop-up window saying "Battery less than 10%. Please charge
soon";
When the battery level drops to 3%, a pop-up window appears
saying "Battery is too low. Watch will power off".
06. Charging
a. Place the Watch on the charging base, and make sure the
charging contacts on the back of the Watch are properly aligned
and attached to the metal pins on the charging base;
b. Connect the charging base to a standard, certified USB charger
(output voltage: 5V, output current: 0.5A and above).
Tips:
When not used for a long time, the Watch may fail to power on.
In this case, you will need to charge the Watch for about 1 minute
before the charging icon appears on the screen.
Before charging, gently wipe the charging contacts clean and dry
to get rid of sweat and moisture.
