I am listing this item to organize the belongings my father carefully kept. This is one of four units, and the "92" sticker he placed for management purposes remains on it. [Product Condition] Operation Check: Power and test light emission have been confirmed. The READY lamp also lights up normally (see photos). LCD Display: Lights up normally, including the backlight. Battery Compartment: No signs of leakage, and the terminals are clean. Accessories: Genuine soft cover [Additional Notes on Appearance] Main Unit: There are faint scuffs and dirt from age and use near the movable part above the light emission section (see photo 3). Cover: The surface has scuffs and whitish dirt from age and storage (see photo 4). The cover functions properly, but please check the photos for its external condition. [Special Notes] Please consider this item understanding that it is used. As it is a precision instrument, it will be carefully packed with bubble wrap for shipping.
