Thank you for viewing. I have confirmed operation with AAA batteries. FM/AM radio reception and sound output from the speaker are OK. Radio recording has also been confirmed. FM is wideband compatible. Recording, playback, and erasing with the built-in microphone have been confirmed. Although it does not affect operation, the HOLD switch is not working. The item for sale is the main unit only; batteries and earphones are not included. Thank you for your consideration.
