Using the Device
Charging the Device
Connect the device to a PC or notebook via the supplied Micro-USB cable. The maximum charge rate is 2A. If you
connect the device to the charging cable, the display will show the current charge status of the battery, current
voltage and the charging time. The charging process will stop automatically and the display will switch off once it is
completely charged (4.2V).
When the device detects the USB charge voltage is less than 4.5V, it will stop charging and the screen will display
"Check Charger". If using a wall adapter, make sure it is suitable for charging with a current of 5V/2A.
Battery Power and Lifetime
When the battery is not in operation for long periods of time, it loses – in accordance with the industry standards
and norms - after 3 months 5% to 10%, after 6 months 15% to 20% and after one year 25% to 30% of its power.
We recommend that you charge the battery at least every 3 months to ensure a long service life.
