8.9.3 Microphone Removal and
Replacement
Tools Required:
1/8 " Flat Blade Screwdriver
3/8" Open End Wrench
The entire microphone is replaced the same as the
earphones by removing the wire lugs from the com-
munications posts and replacing the entire unit. If a
wire is broken it can usually be cleaned and soldered.
1) Remove the nuts and washers from the communi-
cations posts. If you are using the optional terminal
block this may be where the wires from the earphone
and microphone are connected.
2) Lift the terminal lugs off of the communications
posts. NOTE the position of the terminal wires.
They need to be installed in the same order.
3) Slowly pull the microphone out of the oral nasal
mask. The wires that connect it to the communica-
tions posts will follow.
4) Install the terminals for the new microphone.

NOTE that the wires must go on separate terminals
as before.
5) On helmets with terminal nuts, tighten the terminal
nuts carefully, using a small drill bit, pin punch or
opened large paper clip in the post hole to keep the
post from turning. If the posts turn, it means that
the seal made by the silicone sealant on the helmet
shell has been broken. If this happens the posts will
allow water to leak into the helmet.
WARNING
Take care not to break the seal made by
the silicone sealant where the communi-
cations posts penetrate the helmet shell.
If these posts turn, the helmet will leak
and resealing using silicone sealant will
be necessary.
