Configuring the Boom Microphone
(Figure 7)
The boom microphone is commonly worn on the left side but can be installed on
either the left or right ear cup. To move the mic from one side to the other:
1. Identify and pull out the two-pin plug that
attaches the boom mic to the ear cup.
2. Unscrew the knurled screw that attaches the
boom assembly to the bottom of the ear cup.
3. Remove the knurled screw from the locking
clamp and reverse it so that the clamp will
position the boom at the outboard position on
the headset.
4. Position the boom under the opposite ear cup,
and thread the screw in to the ear cup.
5. Re-orient the boom so that the mic symbol faces the user’s mouth.
6. Tighten the knurled screw until boom is secured.
7. Plug the two-pin plug into the jack at the back of the new ear cup. Note that
the rubber insert for the plug has an offset shape so that it will only insert in
one direction.
Wearing the Headset
(Figure 8)
(Note: If mounting the headset to the helmet with the
optional Rail Mounting Kit, please see instructions beginning
on page 10.)
1. Identify the left and right ear seals. The Power/Volume
buttons are on the left ear cup.
2. Place the headset over the head.
3. Adjust ear cup height by pulling or pushing on the cups
until the ear seals are securely positioned over the ears.
Adjustment is accomplished by extending and contract-
ing the ear cup frames on either side of the ear cups
while holding the headband in place.
4. For effective sound protection, be sure that the ear
seals are completely sealed around the ear and obstacles
such as hair, jewelry, or clothing are out of the way.
Boom Mic Placement
(Figure 9)
The boom is flexible and has a length adjustment screw to ensure proper placement
for effective communications.
1. Position the boom microphone so that the
microphone is about ¼ inch from the mouth.
2. To adjust boom length, loosen the screw, position
the mic at the desired length, and re-tighten.
3. Position the mic element so that the mic symbol
on the boom faces directly toward the user’s
mouth.
