(III) CHARGING THE LITHIUM BATTERY
To charge the battery using an external adapter, connect the device
through the mini-USB port to a power source (5V DC/≥500mA, not
provided). While charging, the battery symbol shown on the display
moves from right to left, and stops when the battery is fully charged.
A computer with a USB jack can also be used as a power source to
charge the battery. After installing the lithium battery, connect the
device to a computer with the provided USB cable.
NOTE:
-When using the battery for the first time, please charge it
continuously for more than 6 hours, but not more than 12 hours.
After charging the battery for the first time, you can fully charge
it within 3-5 hours.
-When not using the device for a long time, please remove the
battery.
-AC current can interfere with the reception of radio signals; do
not charge the battery while listening to radio.
-The power adapter, as well as connecting with a computer, can
only charge the lithium battery. It cannot replace the battery as
a power source for playing audio or listening to radio; the
battery needs to be inserted into the device.
-When charging the battery through a computer, we recommend
using the provided USB cable; otherwise it may affect the
charging time and performance of the battery.
