Model: NET JUKE NAS-D55HD HDD Capacity: 80GB (69.2GB user space) Functions: CD playback, ANY MUSIC, HDD music playback Speaker Brand: SONY Thank you for viewing. I've used this for many years and found it easy to use, but I'm selling it because I've started using subscription services more. Set Contents: Main unit, speakers (1 pair), remote control, and a simple AM antenna. (See photo 1) FM antenna, terminal cover for Walkman use, instruction manual, box, batteries, and LAN cable are not included. Appearance: Something seems to be stuck on the top of the main unit, and I tried to remove it, but I couldn't. Other than that, it's relatively clean, but there are signs of use with scratches. (Please check the photos) Both speakers have no scratches or fraying on the front covers. Also, the speaker cones have no tears or scratches. They are relatively clean. The remote control is clean with no particular scratches. Operation Check: I have checked almost everything I could regarding operation. Wired LAN connection OK. (Network server recognition, time setting, song information reading) However, the ANY MUSIC service operated by SONY is no longer available, so it cannot be used. Wireless LAN connection was not confirmed because I didn't have a compatible wireless LAN adapter. WM port (for Walkman) was not confirmed because I don't have a Walkman. Headphone jack OK. Audio IN jack OK. CD playback OK. (I think the reading head has less deterioration because it's used infrequently) Reading from CD, radio, and audio IN to HDD OK. Transfer from HDD to USB memory and from USB memory to HDD OK. However, only mp3 data is possible due to the specifications of this unit. AM and FM radio OK. Monitor output terminal is not confirmed. All buttons on the main unit work OK. All buttons on the remote control work OK. No crackling sound from the volume control. No problems with the screen display. That's all for the checks, so please understand that I cannot support any unconfirmed parts or functions, as I haven't used all the functions myself. Other: Initialized. There is no instruction manual, so please download a similar one from the internet. As of October 2025, the NAS-D500HD was downloadable. Thank you.
