ROLAND JV2080

I purchased this item as a fully functional used unit four years ago, but I haven't used it much, so I'm putting it up for sale.
There are scratches and other marks on the body.
↓ Here are the items confirmed and notes regarding this listing:
・Performance and sound generation using a MIDI keyboard.
・Operation of each button for sound selection and editing.
・The Value dial knob feels a bit loose but is usable.
・There seems to be no crackling in the volume knob.
・The internal battery has been replaced with a new Panasonic battery.
・Please note that the display appears slightly dimmer than it shows in camera photos. Searching for images of the same model online often shows displays of similar or lesser brightness, so it's unclear if this is the default or due to age.
・Output was only confirmed via line out and phone out. I did not notice any particular noise in my usage environment.
・MIDI IN was the only MIDI function confirmed.
・The data card slot has not been tested as I do not have a card.
A power cord and instruction manual are included.

Thank you.
