Thank you for viewing. Recently, there have been some people with poor manners, so please read my profile to the end and understand it before proceeding. This product is a SONY BDZ-AT770T (2011 model) Blu-ray recorder. It still seems to be working at present, but as it is an old device and a personal listing, I cannot guarantee it if any problems occur, so I am listing it as junk and for parts. ★Operation check contents★ ・Broadcast reception, recording (simultaneous recording of 3 programs) and playback ・BD/DVD playback and dubbing ※Regarding writeable discs, there have been cases where inexpensive overseas products sometimes do not read, so please understand that not all product specifications and standards can be used. Operation checks for functions other than the above, and connection to a network environment, have not been confirmed. ※I am explaining the situation that I have been able to confirm, so functions other than the above are unknown. As this is an old device and the manufacturer's warranty has expired, please do not purchase it if you are looking for a perfect, fully functional product, or if you are overly concerned about details. ★Included accessories: AC cord, B-CAS card. ★Exterior and interior cleaning completed ※Front panel glass coating ※Due to being a used, junk item, no returns or refunds are accepted. ★No price reduction due to included shipping. ★Operation check date: June 26, 2025 ★Recently, there have been many people who do not smoothly provide receipt notifications even though the product has arrived. I understand that you may be busy for various reasons, but as this is a personal transaction between individuals who cannot see each other's faces, please only proceed if you can be flexible. ・HDD capacity: 500GB ・Number of programs that can be recorded simultaneously: 3 programs
