LOCAL HEADSET CONNECTION
Insert the headset/microphone into the 4 pin XLR connector on the front panel. See the mi- crophone connection diagram (Figure 2) if other than a Telex Headset is used.
HEADSET MICROPHONE SELECT SWITCH
If the headset you are using has an Electret microphone, the local microphone select switch must be in the “ELT” position (Electret). This switch is located on the rear panel. A +5 volt bias is available at the micro- phone plug for electret use.
If you are using a headset with a dynamic mi- crophone, place the local microphone select switch in the “DYN” position (Dynamic).
NOTE: FOR PROPER OPERATION YOU MUST MATCH THE TYPE OF MICRO- PHONE YOU ARE USING WITH THE DYNAMIC/ELECTRET SWITCH LO- CATED ON THE REAR OF THE UNIT.

In the Continuous mode the transmitter will be on at all times regardless of whether the portables are on or not.
In the Remote mode, the only time the base can transmit is when a portable unit is turned on.
