Troubleshooting — Hardware issues

SD Card Not Detected

• Ensure the card is inserted before powering on the device. The SD/SDHC card must never be inserted or removed when the player is powered.
• Check the card format:

  Type	Required Format	Minimum Capacity
  SD	FAT16 or FAT32	64 MB
  SDHC	FAT32	4 GB

• Ensure the card is fully inserted into its slot. To remove it, gently press it to unlock, then reinsert it.

Trigger Input Not Responding

• Check the wiring: The contact must be established between the In terminal and the ground G on the 3.81 mm Phoenix connector.
• The contact must be held long enough: The debounce time is fixed at 100 ms — a shorter pulse will be ignored.
• Check the folder configuration on the SD card: The trigger behavior depends entirely on the folder name. In the absence of Folder No. 0, the player defaults to mode 0.
• In 1x0 mode (non-re-triggerable), a new pulse during playback is ignored — this behavior is normal.

LED Blinking Slowly

The player is in an error state. Possible causes:

• The memory card is missing or empty.
• The card is not recognized (incompatible format or faulty card).
• The files present are not in a supported format.
