The following is information to help troubleshoot in the event that a computer does not recognize the R-07 when attempting to transfer audio files:
R-07 SETTINGS
- When connecting the R-07 to a computer, a USB Mode window will appear on the R-07's screen. Be sure to select "Storage", press the red record button and wait a few moments. This allows the computer recognize the R-07.
- If this does not appear, check this in the system:
a. Check that the microSD card is inserted into the R-07.
b. Press the MENU button until the main screen appears.
c. Connect the R-07 to the computer via USB.
d. When the "Select USB Mode" screen appears, use the down arrow to select "Storage" and then press the red record button.
USB
- IMPORTANT: Do not use a micro USB cable that is designed only for charging a device. Charge-only cables cannot transmit data. Check the documentation of the cable being used to be sure that the cable is not designed for charge-only.
- Try a different USB port on the computer and/or a different USB cable.
Note: Do not connect the recorder to a USB hub while troubleshooting. - Be sure that you are connecting to a USB 2.0 port on your computer; or a USB 3.0 port with backwards compatibility. Check the USB 3.0 specifications of your computer to determine if there is complete support for USB backwards compatibility.
POWER
- Be sure that the computer is supplying at least 350mA of power to the USB port.
- Test with new, unused Alkaline or Nickel Hydrogen batteries.
Note: Lithium batteries are not compatible with the recorder.
microSD CARD
- Test with the microSD that was included with the R-07 and not a 3rd party microSD--just while troubleshooting.
- Be sure that the microSD card being used is compatible:

- You may have a fragmented memory card--due to improper ejection from a computer, power loss while recording, not formatting a new microSD card, etc. We would recommend formatting the microSD card to alleviate the possible fragmentation on the card.
NOTE: Formatting a memory card will delete all contents on the card:

COMPUTER
- Be sure to log onto your computer as a user with administrative privileges.
- Close/turn off system monitoring/anti-virus software temporarily--this may be preventing your computer from recognizing the recorder.
- Be sure the computer's operating system is running at its latest version.
- Test on a different computer (if available) to rule out a computer related issue.
