Panasonic VE-GDW54-W + KX-FKD353-W1 Set This is a popular cordless phone set that can be linked with a smartphone. Purchased about 8 years ago, the main unit (VE-GDW54-W) was installed in the living room, but it was rarely used as smartphones were primarily used. The unit has been tested and confirmed to be in working order, and has been cleaned. The sub-unit (KX-FKD353-W1) was kept unused. Upon testing for sale, the display showed "Please insert battery," so operation could not be confirmed. It is likely that the battery needs to be replaced as it was probably left in the unit for a long time. Overall, there are signs of aging such as yellowing, scratches, and dirt.
