Push-to-Talk/Lock-to-Talk Switch
To enable the talk function on the base station press
and hold down on the talk button and begin talking.
Releasing the talk button will discontinue the mi-
crophone audio. For continuous talk, quickly press
and release the talk button. This enables the talk
function as long as you want. To release the talk
function press and release the talk button once more
and the talk function will cease.
NOTE: The talk LED will be illuminated wherever
the talk function is activated.
Local Headset Volume
Adjust the volume control on the base station by ro-
tating the Volume control either clockwise or coun-
terclockwise as required for comfortable listening
volume.

Microphone Gain
The microphone gain of the local headset may need
to be adjusted for various audio conditions. The
talk/overmodulation (OM) LED should be green if
the local headset microphone has been activated.
This LED will turn red when Mic Gain is too high
and will need to be turned down. If the LED does
not flash red at all and the audio is low, the gain
may need to be turned up. The gain should be ad-
justed so the LED flashes red only on loudest
speech.
Using the plastic screwdriver (supplied), adjust the
control appropriately. Note that the volume heard
can also be adjusted by changing the spacing be-
tween the microphone and your mouth.
