I've been using it for about a year. There is a red scratch on the top of the main unit, but operation has been confirmed without any problems. Retail price: 398,000 yen This is a "communication device" that allows you to create sentences using the slightly moving parts of your body. It can be used in cases where communication with others is difficult, such as when a person has a physical disability and cannot speak or point. It also supports people who can move their head and neck, such as those who are losing the ability to move their bodies due to ALS. Switches need to be purchased separately. Included items: Main unit AC power adapter "Ossucchi" (likely a brand name or specific device) Infrared sensor ets (likely an abbreviation, possibly for "etc.") There are no instructions, so you will need to search online to learn how to operate and set it up. The infrared sensor also supports the operation of TVs and remote controls. The "Ossucchi" can be operated by setting up a separate button, even in situations where a nurse call cannot be pressed by hand. #FineChat #CommunicationEquipment #CommunicationDevice
