Used from 2018 to 2023, but no longer needed due to relocation, so I am selling it. Only the main unit and the power cord are included. Initialized. I accessed the main unit and confirmed its operation. There are some label marks on the main unit. It was kept in a smoke-free environment, indoors with air conditioning. It has been used continuously for a considerable amount of time, so please purchase only if you understand this. Shipping may be delayed during the New Year's holiday period.
