SD Repeater Compatible with PROGRESS IN ENGLISH Purchased in 2013 as a designated item for my daughter's combined junior high and high school. It was mainly for self-study, so it was only used for the initial startup and to check the recording function, and has hardly been used. (I had experience living abroad and didn't need to use it, but I had to buy it because it was a designated item.) For this listing, I confirmed that it works with the adapter and batteries. ① Main Unit EDEC SDE-100, which has an MP3 playback function and supports SD cards. - Model Name: SDE-100 - Accessories: Instruction manual, earphones, AC adapter, PROGRESS IN ENGLISH book 1 SD card - Functions: SD card compatible, MP3 playback - Brand: EDEC ※ There is also a black SDE-200 purchased in 2018 (used by my younger child, this one shows signs of use and has no accessories). This is considered junk, but if you need it, please contact me and I will add it free of charge. ② PROGRESS IN ENGLISH SD Cards - Books 2-5 are all available. - Please note that there are marks on the surface of the book 2 case as if a sticker has been peeled off. ※ Textbooks are not included. Thank you for viewing.
