Trouble Shooting

• The player can’t play the music/video/photo/books, which its file format is claimed that can be compatible with the device

  • The playback of files is affected by various factors such as bit rate, file size, file integrity, file format, etc.
  • If the file you imported into the player cannot be played, please contact us directly via email and attach a copy of the file so we can investigate.

• FM radio cannot be turned on

  • The playback effect of FM Radio will be affected by the location and the strength of the signal.
  • The FM radio needs to be plugged into a wired headset/headphones as an antenna to turn on. If the headset is plugged in and the fault persists, the 3.5mm port is likely in poor contact. Please replace one headset and try again.

• This device is used abnormally
  Please restore the factory settings to see if it returns to normal; use the charger to activate the battery, and try to restart it on the premise that there is a certain amount of power, or contact our after-sales team for a system refresh.

• The device does not respond to charging or connecting to the PC

  • In a normal shutdown state, when charging with a USB-C cable connected to a computer or a power adapter, the player will usually light up and display the brand logo and remaining power.
  • Whether the USB-C cable or power adapter is damaged: Connect the player by replacing it with another normal USB-C data cable and power adapter to check if it can be charged.
  • Whether the connection is poor: Repeatedly plug and unplug the USB-C cable to test whether the charging can be resumed. If it can be charged at a certain time, it means that the contact is bad.
  • Whether the device’s USB-C port is damaged: Connect the player to a computer or power adapter with an available USB port with a working USB-C cable. If the fault persists, the USB-C port of the player is damaged.
  • If it is confirmed that the USB cable and the charging port are normal, it can be determined that it is the fault of the player itself. Please contact after-sales support for a replacement or refund.

• Noise
  Please check whether there is external matter in the headphone plug, and double-check whether the audio file is damaged.

• The SD card is not working properly
  You may be experiencing any of these issues with your SD card:

  • The SD card is not detected by your device.
  • Slow file speed transfer to and from the SD card.
  • SD card ejects automatically/ Does not stay in the card slot.

• Troubleshooting:

  • Re-insert it into the M4 Pro player.
  • Check the SD card for physical damage.
  • Check if the SD card is FAT32 or EXFAT.
  • Restart the player or factory reset.
  • Make sure that the SD card’s metal teeth are clean.
  • Make sure that the SD card has sufficient free storage for your needs.
    If you still run into any issues, email us with a video or photo showing them.

• The button has no function
  Please restart the machine and try it again

• Bluetooth is intermittent

  • The range of the Bluetooth connection is approximately 40 feet (12 meters).
  • Its performance may vary depending on obstacles (people, metal, walls, etc.) or the electromagnetic environment.

• Troubleshooting:

  • Change the position or location of the unit or connected device.
  • Place the devices closer together to improve signal transmission.
  • Close applications that you are not using to avoid slowing down the Bluetooth transmission.
  • Keeping both the M4 player and BT headset fully charged will prevent some issues from cutting out.
  • Check the specifications of the format of the audio file. The sound may skip if the music being played has a high bit rate.
    ◎If the problem remains, email us with your Bluetooth headphones/speaker brand and model for further assistance or replacement/refund.
