Proper Fit
•The length or vertical fit of the headset ear dome is adjusted by the headband. 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
ONLY, as shown in the diagram below.
Rotating the mic boom in the wrong direction may damage the boom or wiring.
•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.
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.
Headset Volume
Turn the intercom volume down. Preset each headset volume to the highest setting (full clock-
wise). Set the intercom volume to a level above the normal comfortable listening level, but at a
level which does not cause distortion. Reset the individual headset volume for best listening level.
Intercom Communication
The microphone on the FH-10S headset is always active for communication on the intercom.
Simply speak into the microphone to be heard over the intercom.
Radio Transmit
The FH-10S headset has a red Push-To-Talk (PTT) button on the ear dome. Pressing this
button will key the radio. Press and hold the PTT while speaking into the microphone to
transmit on the radio.
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 your local Firecom dealer.
