CASIO EX-word DATA PLUS 8, XD-U8600 model, 160x128 screen, USB connection possible. It can be operated with your finger, but a stylus is included. Dry cell batteries cannot be used. The power supply is not a dedicated one. (The connector has a special shape.) Therefore, I am using one for other devices, but I think there are no problems with the operation. Please download the manual from the internet. - Model: XD-U8600 - Brand: CASIO - Function: EX-word DATA PLUS 8 - Power supply: Alkaline batteries LR6 / eneloop / Rechargeable battery EVOLTA - Screen size: 160x128 - Keyboard: Japanese layout - Connection terminals: USB connection Thank you for viewing.
