BDZ-AT500 This item was in use until recently. Initialized. Terrestrial digital broadcasting dual recording/playback OK. DVD and Blu-ray recording/playback OK. Remote control operation OK. No instruction manual. Disc tray has issues opening and closing. - After opening, it sometimes closes automatically even without the close operation. Playback is not affected. Other than the above, I haven't experienced any particular inconvenience, but as it is an older model, there is no warranty for any malfunctions. If you have any questions, please feel free to ask, and I will answer them as best I can.
