LITHIUM BATTERY SAFETY INSTRUCTIONS
● Improper replacement of a lithium battery may result in an explosion. Replace only with a lithium battery of
the same type or equivalent (the lithium batteries used in this device are 18650 rechargeable Li-ion
batteries with a protection circuit).
Do not charge non-rechargeable batteries.●
Do not expose the batteries to heat sources (e.g. sunlight, fire), low temperatures, humidity, or high ●
pressure.
Dispose of a battery properly and prevent children from playing with electric currents.●
Do not short-circuit or disassemble a battery. If a battery is seriously inflated, please do not continue to ●
use it.
If not using for an extended period of time, remove the batteries and store them in a safe manner. Please ●
use non-conductive material to wrap a battery in order to avoid direct contact with metal. You can avoid
performance loss by keeping the batteries in a cool and dry place.
Please consciously abide by aviation regulations; lithium batteries are often prohibited from placing into ●
checked luggage.
CHARGING THE 18650 BATTERIES
When the battery icon is displayed as “ , this indicates that battery power is about to run out. ”
To recharge the 18650 lithium batteries, connect a DC 5V/2A charger to the charging socket on the left
side of the device using a USB-C charging cable. While charging, the charging time is shown and the
charging indicator “Charge” flashes on the display and stops flashing once charging is complete.
Notes: In order to extend battery life, when the lithium batteries are fully charged but the device has not been
used for 6 days, the device enters into a self-discharge state. When the batteries are discharged to a safe
storage state (the remaining power is about 70%), the regulated self-discharge stops.
Attention!
Only use chargers that are appropriately certified and meet the safety standards in your region.●
Only use lithium batteries with built-in charge and discharge protection circuits. ●
Note:
To avoid electrical noise interference, do not charge the battery and listen to the radio at the same time.●
