USB Port Charging
 To charge the radio, insert the supplied USB 
cable to the power source.
 The charging indicator will stay red. After 
fully charged, the red light will turn off.
 It takes 4 hours for the internal 1100mAh 
Li-ion battery to be fully charged. 
 When completely charged, the battery will 
deliver 9 hours of radio play(depending on the 
volume) or 8 hours of Bluetooth speaker time.
Product Features
 This product uses 1100mAh, rechargeable, 
built-in polymer lithium battery. It has passed 
the safety test and certification, and the 
capacity is larger than most of the same size of 
the Bluetooth speaker, so there is a longer 
working time.
 This product uses a high-end professional 
radio chip, using a special antenna and 
matching circuit, coupled with other 
professional-grade circuits, making its 
receiving sensitivity better than other 
performance.
