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.
