Solution
1.
Make sure the Micro SD card / USB flash drive are working
properly. Check the audio files for supported format: MP3/WMA/
WAV/APE/FLAC.
2.
Besides the case above, there may be an issue with the Micro SD
card / USB flash drive compatibility.
When formatting the Micro SD card or USBB flash drive, we recommend
using a FAT 32 file format.
The most likely cause is an internal speaker system defect. Try long-
pressing 1 and hold the button for 8 seconds. This resets the speaker.
1.
Make sure the speaker is in an area covered by FM signal.
2.
Adjust the speaker orientation to improve the antenna direction.
This may improve reception quality.
3.
Make sure that, while in FM mode, you long pressed 1 and
activated the auto-tuning of FM stations.
