HEADSET CONNECTION

Insert the headset/microphone into the connec-

connection diagram (Figure 5) if unit other

than Telex is used.

Figure 27

Connecting Headset

DYNAMIC/ELECTRET SWITCH

If the headset you are using has an Electret mi-

crophone, the dynamic/electret switch must be

in the “E” position (Electret). This switch is

accessible by removing the belt clip and re-

moving the battery holder. A +5 volt bias is

available at the microphone plug for electret

use.

If you are using a headset with a dynamic mi-

crophone, place the dynamic/electret switch in

the “D” position (Dynamic).

NOTE: FOR PROPER OPERATION YOU

MUST MATCH THE TYPE OF MICRO-

PHONE YOU ARE USING WITH THE DY-

NAMIC/ELECTRET SWITCH LOCATED

INSIDE THE BATTERY COMPARTMENT.
