After purchasing this used in the spring of this year, I increased the HDD to 2TB and used it for a while. However, I purchased a model that can record 4K programs, so I decided to sell it since I hardly used it after replacing the HDD. The cooling fan is also quiet, and the basic operations at the time of listing are problem-free. Recording and playback with the DVD/BD drive can also be done normally (see images). The recorded content on the HDD will be sent as is for operational confirmation, so please format it after you receive it (see images). Operational confirmation was performed with a remote control (N2QAYB000993) that is currently in use with another model, so this remote control is not included. Please understand. There are some scratches on the exterior. The 2TB HDD uses a NAS-compatible Western Digital Red 2TB AV mode compatible drive, so you can use it with confidence in the future. I lack specialized knowledge and have not confirmed other operations. Also, since the operational confirmation was done at the time of listing, please check the images carefully. Although it was confirmed to be working, I cannot provide any future operational guarantees after arrival, so please understand. Since it is an old model, except for the case where the power does not turn on after the product arrives, it will be considered as junk, and I will not be able to provide any support even if there are any defects after shipping, so please understand and acknowledge this. The item includes the main unit and a glasses cable (unconfirmed for power-on, which I had on hand).
