White IC recorder with SD card slot, tabletop style. - Model Name: ICD-LX31 - Color: White - Features: SD card slot - Features: Large speaker - Design: Tabletop style - Features: Date search button Thank you for viewing. I have confirmed the operation. Recording, playback, deletion, external microphone input. (Not all functions have been checked) The SD card has been formatted. The included SD card is inserted in the main unit. The included AA batteries are not included, so I have inserted Panasonic alkaline AA batteries for testing. (Expiration date has passed) My family purchased this and used it a few times to record choral music. Thank you for your consideration.
