If recording fails, the problem is often the USB device or storage.
Steps to try:
Insert a USB stick — recording requires one to be present.
Check free space — move older recordings to a computer if the USB stick is full.
Use the right drive format — FAT32 is usually required. Reformat the drive if needed.
Avoid slow or very large drives — some units can’t write to drives bigger than 32 GB or with very slow speeds.
Check file limits — long sessions may exceed the maximum file size; try shorter recordings.
Still having trouble?
Try a smaller USB stick (8–16 GB) to confirm compatibility.
