I was using these until a few years ago, but I am selling them now to organize my equipment. Each piece of equipment has been tested for power and operation. There are no paper manuals, but I will provide them on a data medium if you wish. Please check the condition of the exterior in the images. Please check the photos of the product condition and purchase only if you understand. Please refrain from purchasing if you are nervous or seeking a perfect product. 《Notes》 No operational warranty (refunds/returns). Due to the nature of used items, the condition at the time of operation check may differ from the condition upon delivery. Also, due to a brief, simple check, there may be oversights or defects. In any case, the current condition takes precedence, and we will guarantee against damage or loss due to shipping accidents. We record the shipment and keep track of part numbers to prevent swapping. Negotiations such as price reductions are OK, but we will delete critical comments and extreme price negotiations. Thank you in advance.
