HEADSET ADJUSTMENT
The vertical fit of the headset is changed by adjusting the headband (FH models) or the
headstrap (UH models).
• Over-The-Head (FH) style headsets (Figure 21): These headsets have adjustable
headbands with slide mechanisms located at each side above the ear domes. If the
adjustment slides become loose, gently tighten the self-locking nuts on the slide
mechanisms.
• Under-The-Helmet (UH) style headsets (Figure 22): These headsets have an
adjustable headstrap to adjust the height of the ear domes.
For maximum comfort, wear the headset as far back on the head as possible, while ensuring
that the ear domes still completely cover the ears. If discomfort is felt in the jawbone, you
are wearing the headset too far forward.
MICROPHONE PLACEMENT
The microphones used on Firecom headsets are noise-canceling electret microphones. The
placement of the microphone is VERY important. For proper operation, the microphone
should be positioned in front of the mouth and no more than 1/8" away from the lips
(Figure 23).
Placement of the microphone is CRITICAL. If the microphone is positioned incorrectly, you
will experience drastic reduction in volume and clarity of the intercom and radio commu-
nication.
LEFT & RIGHT DRESS
The Firecom headsets may be adjusted so that the mic is on the right side (right dress) or left
side (left dress).
Over-The-Head (FH) style headsets: Rotate the Mic Boom ONLY in an upward
•
direction (Figure 21), page 20.
ALWAYS rotate the Mic boom upwards as shown to prevent damage to the Mic
Boom and the Mic Cable.
• Under-The-Helmet (UH) style headsets: Rotate the Mic Boom and the rear
Headband ONLY in an upward direction (Figure 22), page 21.
ALWAYS rotate the Mic Boom and the rear Headband upwards as shown to pre-
vent damage to the Mic Boom, the Mic Cable and the Headband Cable.
HEADSET VOLUME CONTROL
Located on the ear dome of each Firecom Headset is a volume control for adjusting the vol-
ume of headset speakers. This allows each user to adjust the volume to the preferred level.
Turning the Volume Control clockwise increases the volume, turning the control counter-
clockwise decreases the volume.
