Connect the DW-90 to your computer using the appropriate USB cable. The device should be recognized as a removable drive, allowing you to drag and drop files onto your computer.

To delete a recording, select the file you want to delete, then press and hold the 'Erase' button until the file is removed. Confirm the deletion if prompted.
Poor recording quality may be due to low battery power or selecting a lower quality recording mode. Ensure batteries are fully charged and consider using SP mode for better quality.
Yes, you can use NiMH rechargeable batteries. However, ensure they are fully charged and compatible with the DW-90 specifications.
To reset the device, remove the batteries, wait for a few minutes, and then reinsert them. This will reset the device settings without affecting the recorded data.
Ensure the microphone is not obstructed and keep the device away from sources of interference. Adjust the microphone sensitivity settings if necessary.
