Fitting the Ear TipsBefore inserting the ear tips, attach lapel clip toclothing. Do not force the ear tip into the ear canal.Using ear tips correctly requires a little practice. TheM1 boom is designed to be worn on the left side.Start with the ear tip that is not connected to theboom. Be sure your hands are clean and that the tinytube inside the ear tip does not extend beyond thefitting material.

Custom Ear MoldWe recommend custom ear molds for your Mach 1headset. LightSPEED Aviation, and our partnerSensaphonics Hearing Conversation, partner tooffer a headset with a fit unique to your ear canals.Sensaphonics sound-isolating custom ear plugs areuncompromising. Working from impressions takenby an audiologist, our in-house artisans createprecision earphones that ensure perfect fit,maximum comfort and full isolation. Molds arecustom molded using soft gel silicone, the only earmolds on the market using this material. Thatmeans a better seal and a more comfortable fit.The point of all this is to provide hearing protectionfor pilots. By isolating the ear from unwantedsound, custom ear Molds allow our pilots to hearonly what they want or need to hear withexceptional sound quality.

Foam Ear TipsThe blue MATRIX™ foam is a 'no roll' foam. Rollingor compressing it prior to inserting into the earcanal is not necessary. To fit it into the ear canal,simply follow the instructions on the previous page'Fitting The Ear Tips'. If working with a slow recoveryroll form, hold the foam with the thumb, pointer andmiddle finger. Roll gently and evenly back and forthto compress the foam into a dense cylinder aroundthe imbedded tube. Fit the left ear first, reacharound the back of the head with the right hand(reverse hand placement if starting with the rightear), take hold of the top of the ear and gently pulltowards the back of your head to optimize ear canalclearance.With the ear tip in your left hand, insertthe compressed foam into the ear canal, release ofthe top of the ear with the right hand. Hold the eartip in place for 5-10 seconds while the foam fullyexpands to block outside noise. If placed correctly,

the ear tip adapter should be flush with the earcanal entrance.Very little ear tip material should bevisible. Repeat the steps on the other side using theear tip connected to the boom assembly. Position themicrophone boom at nose level; it will “drop” toproper level when released. After inserting tip, holdit and the boom in place for about 15 seconds untilthe foam fully expands. When the boom is released itshould be off center to the mouth approximately 1/4inch from the lips.

Silicone Ear TipsIf the ear tips are frequently removed and re-inserted,the triple flange silicone ear tips may be the bestselection for the user. If fitting the left ear first, reacharound the back of the head with the right hand(reverse hand placement if starting with the right ear),take hold of the top of the ear and gently pull towardsthe back of your head to optimize ear canal clearance.With the ear tip in your left hand, insert the tripleflange ear tip into the ear canal, let go of the top ofthe ear with the right hand and release the ear tip. Ifplaced correctly, the ear tip adapter should be flushwith the ear canal entrance.Very little ear tip materialshould be visible. Repeat the steps on the other sideusing the ear tip connected to the boom assembly.Position the microphone boom at nose level; it will“drop” to proper level when released.When the boomis released it should be off center to the mouth atapproximately 1/4 inch from the lips.

Dip SwitchesThe dip switches are where you set yourMono/Stereo, and your Comm Priority. Switch 3 isthe Mono/Stereo switch. It should be set accordingto your intercom type. Headset is shipped preset to“Mono” and will distribute audio to both ears ifused with a mono intercom. If using a monointercom with the stereo setting, the audio will onlycome through to one ear. Change the setting tostereo if using a stereo intercom. To change thesetting, move dip switch number 3 down, or to theOFF position. When using cell/satellite phone ormusic interface, audio will come through to bothears regardless of selection of mono or stereo.Dip switch 2 is the Comm Priority setting. It comesset in the ON position meaning that all Comm.Audio takes priority over AUX audio. Any radiocommunications will cause the AUX audio to mutedown about 70% so that you may hear the

transmission. This feature can be turned OFF bymoving dip switch number 2 down, or to the OFFposition. Dip switch 1 is Power, and should be leftin the ON position unless instructed otherwise by afactory authorized service technician. NOTE: Achange in a dip switch setting only takes effectafter power is recycled. Do this by turning the AUXON/OFF off then back on again.

FAQ’sProblem: Ear tips do not deaden sound.Solution: This is likely the result of improper ear tipselection or insertion. Read the Fitting the Ear Tipssection.

Problem: Only one earphone seems to work.Solution: Change mono/stereo switch position. SeeMono/Stereo Switch section. Make sure the ear tip isnot clogged with debris.

Problem: Sound is too loud or too soft.Solution: Due to both the high fidelity and proximity ofthe speakers, the audio volume might need to beadjusted to balance the M1 with other headsets. Firstlower the volume wheel on the control module toprovide comfortable listening levels. Make additionaladjustments to the intercom or radio to increase ordecrease the overall system audio volume.

Problem: Mic is weak or intermittent.Solution: Since the M1 uses a special noisecanceling element, it is important to get proper andconsistent placement. Since this is typically aproblem associated with either mic positioning orthe intercom/radio squelch setting, the mic elementhousing should be positioned within 1/8 - 1/4 inchesfrom the mouth, off-center on the boom side, notdirectly in front of the mouth. Properly placed, youcan now adjust the squelch setting to get optimalperformance. Adjust the squelch control to minimum(open mic) and begin to turn it up.When the ambientnoise level drops away, speak in a normal voice andyou should break through and be clear and audible.If that does not resolve issue, return unit tomanufacturer for repair.
