CONNECTING A MICROPHONE/
SPEAKER
You can connect an external communications headset, con-
sisting of a microphone and speaker, to the transceiver so you
can use it privately. Lift the hinged, rubber dust cover from the
MIC and SPK jacks on the top of the transceiver, then insert
the plug of an optional voice activated headset with micro-
phone, such as Cat.No. 19-312, or an optional communication
headset, such as Cat. No. 19-316, into the jacks.
Caution: Use only microphone speaker accessories that do not
share a common ground for the speaker and the microphone. Do-
ing otherwise might damage the transceiver.
Note: Inserting the headset plug automatically disconnects the
internal speaker and the push-to-talk (PTT) button.
You can also connect an optional mono earphone, such as Cat.
No. 33-175, into the SPK jack. This lets you use the transceiver’s
push-to-talk button to transmit as usual
