【Panasonic】 Fax Phone, White *Includes Instruction Manual *Junk Item

Panasonic Telephone
KX-PD304DL-W

The main unit has been confirmed to power on, but it has been stored unused for 4-5 years, so it will be treated as a junk item.
Button operation was fine.

A few years ago, the fax function was also working, and there were no particular issues during use. The main unit powered on immediately this time.

The sub-unit would not power on, so it may be due to a dead battery? It is considered a junk item.
The battery was connected to the unit, so it was not possible to try replacing it.

There is yellowing on the entire sub-unit and the bottom of the main unit.
I have cleaned off any removable dirt, but I believe it is insufficient, so please refrain from purchasing if you are concerned.

The instruction manual and box are included, so I would like to ship them as is.

*Please note that shipping will be done via the most economical method.
*Immediate purchase without comments is welcome!
*This is strictly a used and junk item, so please only purchase if you understand this.!
