10: Type-C Port: Charging & Headphone Combo
10.1 Charging:
In the working state, lightly press the "MOD" key to illuminate the battery indicator light, which displays the battery usage
level. When the battery level indicators "1-7" are off and the " " light is blinking, it indicates that the battery is low. Please
charge the device in a timely manner to avoid affecting normal usage. It is recommended to use a charging device with an
output voltage of DC 5V/1A to DC 3A to prevent damage to the lithium battery or the device.
If the lithium battery will not be used for an extended period, please ensure it is removed and stored separately, and make
sure to charge it once a month.
Use the included power cable to charge the radio. During the charging process, the “ ” indicator light will blink. Once
fully charged, the “ ” indicator light will stop blinking.
The typical charging time is approximately 3-4 hours.
10.2 Using as Headphones:
Using the included Type-C to 3.5mm adapter cable, connect the Type-C end to the device’s Type-C port, and insert your
headphones into the 3.5mm jack (headphones must be purchased separately). This will allow you to listen to the product
through headphones. (Note: After inserting the headphones, please adjust the volume to a moderate level to avoid
damaging the headphones.)
This is a Type-C to 3.5mm connection cable (included as a random accessory).
11: Activating the Music Spectrum Light:
In the power-on state, lightly press the “MOD” button a second time to activate the music spectrum light. The music spectrum
light will flash from high to low and from low to high, changing in response to the melody of the music.
To turn off the music spectrum light, press the “MOD” button again.
12: Using the Antenna:
When listening to SW (shortwave), FM (frequency modulation), and WB (weather band) broadcasts, extend the antenna and
adjust its length and direction to find the optimal reception.
*Note: If experiencing strong radio interference causing cross-talk, shorten the telescopic antenna.
For listening to MW (medium wave) broadcasts, the device uses a built-in magnetic antenna for medium wave reception. The
magnetic antenna has a certain directional capability when receiving signals, so rotating the device may help find the best
reception position for MW.
