Hold the microphone bulkhead mount at the
chosen location and use a soft pencil to mark
the screw hole positions on the mounting
surface.
Ensure that the microphone curly cable will
comfortably reach this location BEFORE you drill.
2.
Drill the two pilot screw holes where marked.
3.
Use a short length Philips screwdriver and the
set of two flat screws, spring washers, plain
washers, and nuts to secure the microphone
bulkhead mount at the location site.
4.
Hang the microphone on its mount.
NOTE: (Explorer 721US/EU only) This mic clip has a special magnet glued in the rear of the clip to sense
ON/OFF HOOK. All other mic hangers do not have magnets and therefore cannot be used.
