BATTERY
The player uses rechargeable Li-ion battery. It can use 5V USB charger. Suggest use the specified
1000mA charger.
If sound turns bad, or volume decreases, or playing discontinuity, it means power is getting low. Please
recharge battery as soon as possible.
Don’t play when charging, or else power will not be enough and charge time will be very long, because
playing power consumption is too much. Please use 1000mA adapter to supply enough power.
