Panasonic calls their
new KX-T7765 a "premium" door intercom speaker. It's a step up from the
all-plastic KX-T30865 that's been available since Velociraptors roamed the
Earth, but is less costly than the KX-T7775 with the sexy blue LED that
requires a power supply and an electrical box sunk into your wall.
Besides its nice brushed metallic finish, the chief reason to buy the new
unit is a luminous ring that surrounds the calling button. Unlike other
door intercoms with buttons that light up, it does not require a
conventional power source -- it gets its power from the sun! Once it's
exposed to light for 30 minutes or more, the ring will glow for up to 90
minutes before it fades to black.
The light won't help guide midnight visitors, and the duration and
brightness varies with the brightness and duration of the light exposure
and the ambient temperature. But what the heck, it's free.
The KX-T7765 is compatible with Panasonic KX-TA824, KX-TAW848, KX-TDA and
KX-TDE phone systems. We're trying to find out if it will work with the KX-TD
and KX-TA624 systems. We think it will.
