Electret Microphone, Hi-Lo, Function 7
This function selects high or low gain for an electret microphone.
The “on” setting selects high gain. The “off ” setting selects low gain.
Low gain is useful for high-noise environments.
To select an high or low gain for an electret microphone:
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 “7” appears in the display.
3. Press the talk button to toggle to either “on” for high gain or “off ”
for low gain.
The talk light reveals whether the function is “on” or “off.” If the
talk light is on, the electret microphone is set to “high gain”; if the
talk light is off, the electret microphone is set to “low gain.”
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.
