■ Condition
This is a used item. It was used for about 1 year and then stored for several years. I am selling it because I no longer use it myself, hoping someone else can make use of it.

It was only used indoors and never taken outside. It was attached with Velcro under my desk, so there are discolored areas on the aluminum casing due to adhesive residue. There are also minor scratches, as can be seen in the photos.

The display brightness has decreased, possibly due to long-term storage. It is visible in shade when viewed from the front, but may be difficult to see in bright environments. Since important information is not displayed during normal use, I believe this will not be a major issue in practice, but please be aware of this point.

The price has been set taking these points into consideration.

[Operation Check]
- Audio output from all input terminals: Confirmed
- Battery: Confirmed over 10 hours of continuous use after a full charge
