HEADSET SETUP
1. Headset Adjustment: Use the slide adjustment on each side of the headband to achieve
proper t and size.
2. Mic Position: For best performance, it is recommended the microphone be positioned directly
in front of your mouth, sitting a nger’s width from your lips.
3. SmartBoom Mic Mute: During operation, swiveling the boom
up above the brow at approximately 45 degrees will mute the
microphone. To activate the microphone again, simply lower
the boom back down.
Note: To adjust the boom, swivel it so that the microphone is on the
preferred side (right or left).

OPERATING MULTIPLE MICROCOM SYSTEMS IN ONE LOCATION
Each separate MicroCom system should use the same Group and Security Code for all devices in
that system. Pliant recommends that systems operating in proximity to one another set their Groups
to be at least ten (10) values apart. For example, if one system is using Group 03, another system
nearby should use Group 13.
