Some microphone boom attachment holes get elongated fom Fir wear 'n'
tear. A loose boom means you can't keep the mike close enough ±r your lips
to brush against it when you speak into it-that means poor voice transmission²
Here's how to "³x´ the boom:
•
Unhook the
2
ear cup tension
crosS straps.
•
Unscrew the bolt that holds the
swivel assembly on the helMet.
ReMove the o±tside washer.
•
Peel bAck the Chafing ear c±p
pad to get to the swivel asseMbly
post screw on the inside of the
helMet. Hold the bolt on o±tside
helMet with pLers as yo± reMove the
post screw.
