Handset Interface
If you do not have access to an analog phone line or if the phone
system is a digital or analog PBX, ISDN, or a key telephone
system, you can use the built-in handset interface. Disconnect the
telephone handset from the coily cord and plug the cord into the
RemoteMix Sport PBX Handset Interface Jack. Now select the
handset type on the 3 position switch.
Trial and error works faster than a chart of handset types, but this
basic description may help.

C Carbon
Talkback Feature
A built in speaker lets you monitor the phone line during call setup
and station breaks. The monitor speaker volume is controlled by
the headphone volume control and has an additional on / off switch
(near the A-B-C switch). An internal push-to-talk microphone (see
page 9) also helps when setting up your call. The speaker
switches off when the microphone button is pushed on to prevent
feedback.
