CONNECTIONS
Mic Connector
To connect a panel microphone, such as the RTS model MCP90, screw the microphone into the
Mic connector on the front panel of the keypanel.
NOTE
For Mic connector specifications, see “SPECIFICATIONS” in Section 1.
Headset Connector
The Headset connector accepts a monaural, dynamic-microphone headset (headphones and
microphone). If you use a headset, make sure DIP switch 4 is set to the Open position.
Alternatively, headphones can be connected when a panel microphone is used for talkback. Or, a
handheld dynamic microphone can be connected when a speaker is used for listening. If you use
either of these special configurations, make sure DIP switch 4 is set to the Close position.
NOTE
For Headset connector specifications, see “SPECIFICATIONS” in Section 1.
