One-Year Limited Warranty to Original Purchaser

Sonetics Corporation warrants to the original purchaser of its products, that they will be free from defects in materials and workmanship,

under normal and proper use, for the period of one year from date of purchase. Sonetics Corporation will repair or replace, at its option,

any parts showing factory defects during this warranty period, subject to the following provisions. This warranty applies only to a new

product which has been sold through authorized channels of distribution. All work under warranty must be performed by Sonetics

Corporation. All returned products must be shipped to our address, freight prepaid, accompanied by a dated proof of purchase. The

purchaser voids this warranty if he or others attempt to repair, service or alter the product in any way. This warranty does not apply in

the event of accident, abuse, improper installation, unauthorized repair, tampering, modification, fire, flood, collision, or other damage from

external sources, including damage which is caused by user replaceable parts (leaking batteries, etc.). This warranty does not extend to any

other equipment or apparatus to which this product may be attached or connected. The foregoing is your sole remedy for failure in service or

defects. Sonetics Corporation shall not be liable under this or any implied warranty for incidental or consequential damages, nor for any

installation or removal costs or other service fees. This warranty is in lieu of all other warranties, express or implied, including the warranty of

merchantability or fitness of use, which are hereby excluded. To the extent that this exclusion is not legally enforceable, the duration of such

implied warranties shall be limited to one year from date of purchase. No suit for breach of express or implied warranty may be brought after

one year from date of purchase.

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.

Intercom Communication

The FH701, 702, 703 and the UH701, 702 headsets have a yellow PTT button on the ear

dome. Press and release this button to activate the microphone for intercom communication.

Press and release the button again to turn the microphone off.

The FH704 headset has a red momentary PTT button on the ear dome. Press and hold

this button to activate the microphone for intercom communication. Release the button

to turn the microphone off.

Caution

This Flightcom headset provides 24dB noise attenuation when properly fitted to the user

and worn as instructed. Any modification to the hearing protector such as drilling holes in

the dome, painting or reforming the headband spring, will negatively impact the hearing

protector’s performance and hearing damage could occur.

Federal law requires the following statements:

“Although hearing protectors can be recommended for protection against the harmful

effects of impulsive noise, the Noise Reduction Rating (NRR) is based on the attenuation

of continuous noise and may not be an accurate indicator of the protection attainable

against impulsive noise such as gunfire.”

“The level of noise entering a person’s ear, when a hearing protector is worn as directed,

is closely approximated by the difference between the A - weighted environmental noise

level and the NRR.

EXAMPLE: 1. The environmental noise level as measured at the ear is 92dBA.

2. The NRR is 24dB.

3. The level of noise entering the ear is approximately equal to 92dB (A) - NRR.

CAUTION: For noise environments dominated by frequencies below 500 Hz the

C - weighted environmental noise level should be used.”

Always wear a hearing protector in areas that have been identified as high noise locations.

Care & Maintenance

Repairs or replacement of the headset should be immediately sought if you see any defect

such as holes or cracks in the ear domes, ear seals or headband.

Body oils, perspiration and hair care products will, over time, affect the ear seals. Inspect

the ear seals frequently for signs of wear and replace at approximate 6 month intervals

along with the mic muff (cover).

Do not remove the foam speaker cover.

Never remove the headset from the aircraft jack by pulling on the cord. The

headset should be unplugged at the jack location by pulling the headphone plug

from the jack.

Warranty
