Microphone Placement

Place the microphone in front of the mouth and NO MORE than 1/8" away from the lips as shown in the diagram below. Placement of the microphone is CRITICAL for proper operation.

If the microphone is positioned incorrectly, you may experience a reduction in volume and clarity of intercom and radio communication.

Headset Volume

Turn the intercom volume down. Preset each headset volume to the highest setting (full clockwise). Set the intercom volume to a level above the normal comfortable listening level, but at a level which does not cause distortion. Reset the individual headset volume for best listening level.

Intercom Communication

The headset microphone is always active for intercom communication. Simply speak into the microphone to be heard over the intercom.

Radio Transmit

The LW-10 headset has a Push-To-Talk (PTT) button on the in-line control box.. Pressing this button will key the radio. Press and hold the PTT while speaking into the microphone to transmit on the radio.

Mic Muffs

The headset microphone is covered with a replaceable foam mic muff. This mic muff helps prevent the “pops” and “hisses” that can occur from speaking into a microphone that is close to the mouth.
