Panasonic KX-TGJ310GB telefoon

As a fifth phone on a KX-TGJ324 phone set it works perfectly - but in the booklet that comes with the set it is called KX-TGJA30E, which makes it hard to find as the suppliers do not use this name. The fifth phone was needed because the ring tones on the TGJ phones are not loud enough to be heard throughout the house.
