But.... apparently this was posted on the Multiplex e-list (which I do not subscribe to....)
Anyway.... the gist of it was that the RF signal was traveling down the power leads from the battery....... causing the battery to radiate RF back into the Profi keypads (the battery is directly behind the keypad.) The "Fix"..... which has been done on the radios that the Multiplex tech guy (can't remember his name at the moment) actually got his hands on before sale.... is to mount a flat brass plate behind the battery...... drill a couple of holes through the molded plastic battery retainer..... and solder grounding straps from the new brass plate... to the large, silver tin grounding plate that is already in the transmitter.... Doing this solved some weirdnesses that both Bill Wilson and I experienced with the Profi 4000's.......
