Another blast from the past! Manufactured by EICO Electronic Instrument Co., Inc. Now you can limit long phone conversations at home or office! The FA-20's solid state electronic circuit starts timing automatically when the phone is lifted. A beep-tone will periodically be heard on the phone after a pre-determined amount of time has elapsed. These tones can be preset from 3 minutes to about 10 minutes. The unit will automatically reset for the next call. Unused in original box. Doubt you will find these anywhere else.
