How to use

For wired playback, insert a USB drive or TF (Micro SD) card into the corresponding slot or connect an audio source via the AUX-in port. Use the microphone input to connect a microphone for karaoke or hands-free conversations when a phone is paired. Switch to FM mode to use the built-in radio tuner and adjust tuning with the device controls. Use the speaker controls to adjust volume, skip tracks and change modes as needed.

Recommendations

For clear sound and maximum battery life, keep volume at moderate levels and avoid continuous maximum output. Use Bluetooth 5.0 connection for stable wireless streaming; if interference occurs, move the source device closer to the speaker. When using outdoors, protect the speaker from rain and excessive dust. Charge the internal battery regularly and store the device in a dry place when not in use.
