Electret Microphone, Function 5
This function allows a beltpack to operate with an electret-
microphone equipped headset. It only affects a headset connected to
the main headset jack. Turning this function off reverts the beltpack
to dynamic microphone operation.
To select “electret microphone” for a channel:
1. Press and hold the setup button until the setup information
window displays a “P” and then release the button.
2. Repeatedly press the call button until “5” appears in the display.
3. Press the talk button to toggle “electret microphone” to either on
or off.
If the talk light is on, the “electret microphone” option is on; if the
talk light is off, the “electret microphone” option is off.
4. When you have made your selection, press the setup button to save
it and to exit setup, or press the call button to select other
functions to program.
If you do not press a button within five seconds, the beltpack exits the
setup program without making any changes.
