Charging the battery
The device has a rechargeable built-in lithium-ion battery. It is
charged via USB connection. You are required to charge it when
you use it for the first time.
To charge the battery, connect the larger end of the USB cable to
the USB interface of PC, and connect the other smaller end of the
USB cable to the USB interface of this player. The player enters U-
disk mode automatically. Exit the U-disk mode (remove the player
safely from the PC, but let it still connected), the player enters
charging mode then.
Note: For safety, the charging time should not exceed 8
hours. And since the longevity of the battery bases on the
charging times, please charge the battery after it is
exhausted, and please charge it full once.
To turn on the player while charging:
When the player is charging and shows “charge” (after you
removed it safely from PC, but it is still connected), pressing the
key can be turn on the player and you can use it as usual. But it
can’t be turn off by press and hold the
key.
Note:
For maximum performance, lithium-ion batteries need to be
used often. If you don’t use the device often, be sure to
recharge the battery at least once per month.
