A HI/LO switchlocated on the front permits the user to select a high or lowvolume level. A miniature earphone jack located on the bottom of the case permits the use of an external earphone.The Universal Device Connector (UDC) on the end ofthe speaker/microphone cable provides the connections tothe radio unit UDC. The EDACS Monogram speaker/micuses a Hirose connector to connect to the top panel of theradio. The NPC speaker/mic has a 2-pin molded connectorthat connects to a connector on the top panel of the radio.The speaker/microphones equipped with an antennaconnector permits an antenna to be connected and used inplace of or in addition to the radio unit antenna.
