Powering Your Device

This device is powered by a BL-5C 3.7V rechargeable lithium (Li-ion)

battery. Open the battery compartment and install the battery following the

correct polarity. The device can also be powered by connecting a

DC 5V/0.5A power adapter to the micro-USB type-B socket.

Note: Connecting an external power supply causes interference when

listening to radio frequencies. If experiencing reception difficulties,

disconnect the external power supply and use a battery instead.

Attention! If you use a power adapter, assure that is appropriately certified

and meets the standard requirements for an adapter in your region.

Charging the Battery

When the battery icon is displayed as “ ”, this indicates that battery

power is about to run out. Please charge it in time. To charge the BL-5C

rechargeable lithium (Li-ion) battery, connect a DC 5V/0.5A charger to the

USB socket on the right side of the radio using a micro-USB type-B

charging cable. When charging, the charging time is displayed at the top

right corner of the display while the “Charge” indicator flashes. When

charging is complete, the battery symbol is displayed as “ ” and the

charging indicator "Charge " stops flashing.

Notes:

Assure that the charger is appropriately certified and meets the standard

requirements in your region.

To avoid electrical noise interference, it is recommended not to charge

the battery and listen to radio broadcasts at the same time.

If the device is not used for a prolonged period of time, it is advisable to

charge the battery once every 3 months for about 4 hours. This may

extend battery life.
