BT 6600 TWIN
My 'slave' BT6600 TWIN screen displays OK but there is no sound at all. It doesn't beep when placed in the charger. I cannot call out on it or pick up incoming calls because there is no sound. It is not muted. Volume is set to max. Battery shows charged. I have tried unplugging the base station for 20 -30 seconds as recommended on another post, but this did not work. Grateful for any suggestions.
