Question About AT&T Cordless Telephone 5840

I was recently given this phone and an extra base station for it. One of the phones has a flashing blue light around the ear receiver. I have swapped out the base phone with the other base and it still flashes blue. Does anyone know what this is and if it can be fixed? Thanks.
