My previously used HDD recorder suddenly stopped responding, so I hastily purchased and connected this product. On the same day, I learned that the HDD that had become disconnected could be reconnected by turning the TV's power on and off. I tried this and it worked, so I decided to continue using my previous HDD recorder since it still had the recorded data. Therefore, I am selling this product, which was only connected to the TV for a short time. Included accessories: AC adapter and USB cable. The product box is available, but the original cushioning material for the main unit is not included. I will pack it carefully with air-cushioning material, etc., before shipping. This is a used item, so please understand that it is non-refundable and non-returnable. Thank you for your purchase.
