A Brief Explanation of the Various TALK/LISTEN Button Options

MOMENTARY: By pressing and holding the button for the duration of time it is engaged, you “open” the port. When you let go, you “close” the port.

LATCHING : By tapping the button, you “open” the port and to close, tap again.

Talk Only:   When you push the button, you talk to the destination port, but there is no “listen” function.

Listen Only: When you push the button, you can hear the source port , but not “talk” to it.

Talk & Listen:   When you push the button, you can both TALK and LISTEN to that port, but when you unlatch or take your finger off the button, both TALK and LISTEN go away.

Dual Talk & Listen: By tapping the button, you latch the “listen” on.  To ”talk” to the port, you press the button, then  let go to stop “talking”. You can’t latch both the “talk” and “listen” in this mode…only the “listen”

Talk with a Forced Listen: The “listen” is always on. (To turn it down or off, rotate the knob counterclockwise.) You can either latch or push-to-talk (momentary) your “talk” function. This is the most common scheme used for Party Lines, as it emulates the two-wire environment.
