Mic Cord Stripping Instructions

Be sure the shield wire touches the metal crimp
tab. This helps prevent any AM component of the
transmitter signal from entering the mic and
causing a "whine."
Note that this is opposite from our VHF
transmitter wiring where the shield should not
touch any metal part of the housing.
