This is a cordless handset (BCK-D110) included with the brother (Brother) MFC-J955DN main unit. Includes: * Handset body * Charging stand (BCL-CH20JP) *The main unit (base unit) is not included. After charging on the charging stand, I have confirmed that: * Screen display * Key operation * Menu operation work without any problems. The battery is: Ni-MH 3.6V 800mAh (third-party product) It is installed. It is currently working normally, but the remaining charge and lifespan cannot be guaranteed as it is a consumable item. The exterior is a used item, so there are small scratches and signs of use. Please check the condition in the photos. How about this for adding or replacing a handset? Please purchase only if you understand that this is a used item.
