Proper Fit; Headset Volume Control; Microphone Placement - Flightcom FH Series Manual

Proper Fit

When worn properly, this headset will provide significant hearing protection. If it is not worn
properly, the headset's effectiveness in reducing harmful noise is severely compromised.
• The length or vertical fit of the headset ear dome is adjusted by the headband or head-
strap. Adjust as necessary to achieve a fit that ensures the headset ear dome completely
covers the ear.
• When switching between right and left dress, rotate the mic boom in an upward direction
as shown in the Fig.1 and Fig.2.
Rotating the mic boom in the wrong direction may damage the boom or wiring.
Damage to the headband cable may result from rotating the metal headband on the
UH model in the wrong direction.
• For maximum comfort, wear the headset as far back on the head as possible, while
ensuring the ear dome still completely covers the ear. If discomfort is felt in the jawbone,
you are wearing the headset too far forward.

Headset Volume Control

A detented volume control is provided. Volume should be set at a comfortable audio level
but not so high as to cause audio distortion.

Microphone Placement

Place the microphone in front of the mouth and no more than 1/8 " away from the lips as
shown in the diagram below. Placement of the microphone is critical for proper operation.
If the microphone is positioned incorrectly, you may
experience a reduction in volume and clarity of intercom
and radio communication.
Mic Muffs
The headset microphone is covered with a washable, replaceable foam mic muff. This mic
muff helps prevent the "pops" and "hisses" that can occur from speaking into a microphone
that is close to the mouth.
To clean or replace the mic muff:
1. Remove the o-ring.
2. Slip the mic muff off the microphone.
3. At this time, you can decide whether to
clean or replace the mic muff.
If you clean the mic muff, use a mild detergent, rinse it out well
and let it dry completely before re-installing it on the microphone.
4. Slide the mic muff on the microphone.
5. Install the o-ring on the mic muff to secure it.
Replacement mic muffs may be ordered from Firecom.
