Set Contents: Main Unit VL-MGD10 x 2 Sub Unit VL-VG560L x 1 Charger Set x 2 Battery Pack KX-FAN57 x 1 Main Unit Condition: Units with a battery pack function normally. Units without a battery pack are junk items and display an out-of-range error, failing to connect. There seems to be a reset button, but its location is unknown. Sub Unit Condition: Many small scratches. Buttons respond without issue. The battery compartment is clean with no rust. AA batteries are not included. Charger Condition: Both chargers function without problems. Battery Pack Condition: KX-FAN57: Battery life is low and needs replacement. It can be used while on the charging stand, but it's recommended to replace it with a new battery pack. This is a currently working item, but one of the main units is a non-functioning junk item. Please be aware of this. There are scratches and dirt. Please check the photos. There are no major damages or stains, but there are small scratches and dirt. I hope someone who needs it will use it. Please refrain from purchasing if you are sensitive to used items.
