|---|---|
| Device does not power on. | Battery is depleted. Charge the device fully. Ensure the power switch is in the 'ON' position. |
| Cannot record. | Memory is full. Transfer files to a computer and delete them from the device. Device may be in playback mode; stop playback before recording. |
| Poor recording quality. | Microphone may be obstructed. Ensure the device is placed in an open area. Adjust recording sensitivity or disable voice activation in noisy environments. Check recording format settings (WAV offers higher quality than MP3). |
| Device not recognized by computer. | Ensure the USB-C cable is securely connected. Try a different USB port or cable. Restart both the recorder and the computer. |
