This little time-saver gives you call control you simply can’t get with an auxiliary telephone and a couple of switches. An 8 pin RJ45 modular cable provides remote power so there is no need for batteries or an external power pack. The Call button will flicker when a call comes in. Press this button to answer or place a call. The button will stay lit when a call is present. When you dial on-air, the tones go out on the line, and do not come back mixed with the dial tone or caller signal. Guest Module 1 was designed exclusively for JK Audio Broadcast Host, Innkeeper LTD, or Innkeeper 1x/1rx digital hybrids.
