Talkback Amplified Speaker Option

The talkback amplified speaker option enables a talkback speaker to be provided in areas
where a telephone is not needed. In this configuration, the HESB is connected to the 600Ω
(duplex) output Page RCA jack on the Base Unit and is used as the amplifier and speaker.
A door phone unit (MDFB) is connected to the HESB, and serves as a microphone to provide
talkback operation. (The MDFB push-button is inoperative, and the unit serves only as a
microphone for talkback and not as the normal door phone.)
