INSTALLATION OF MODULAR HELMET KIT
1- NOTE THAT THERE ARE MANY HELMET STYLES, THIS INSTRUCTION USES THE SHOEI NEOTEC HELMET
AS ITS BASE. WHILE MOST HELMETS MAY HAVE A SIMILAR DESIGN, THEIR SLIGHT DIFFERENCES MAY REQUIRE A
DIFFERENT MOUNTING LAYOUT.
THE 14-5028 MOUNTING PLATE HAS BEEN DESIGNED WITH FOUR HOLES THAT ARE
DRILLED AND TAPPED TO ACCEPT 6-32 SCREWS.
THE HELMET KIT CAN BE AFFIXED TO EITHER SIDE OF THE PLATE USING ANY OF THE HOLES TO
PRODUCE A MOUNTING ARANGEMENT THAT WORKS FOR YOU AND YOUR PARTICULAR HELMET.
2- THE MICROPHONE ELEMENT HAS A SIDE THAT IS LABELED “TALK”. THIS SIDE MUST BE FACING YOUR MOUTH.
THE ELEMENT MUST BE CENTERED AT A DISTANCE OF 1/4 INCH FROM THE MOUTH - A.K.A.“KISSING DISTANCE”
3- MOUNT THE HELMET KIT TO THE PLATE AND DRY FIT THE MOUNTING TO THE HELMET TO THOUROUGHLY VERIFY
FIT AND FUNCTION PRIOR TO APPLYING THE VHB MOUNTING TAPE AS EXCESSIVE REPOSITIONING OF THE
ADHESIVE TAPE CAN ALLOW IT TO PICK UP RESIDUAL DUST,DIRT,GRIME, AND IMPAIR ITS BOND STRENGTH.
4- PRIOR TO APPLYING THE VHB MOUNTING TAPE MAKE SURE YOUR HANDS ARE FREE OF DIRT AND OIL.
DO NOT TOUCH THE ADHESIVE FACE OF VHB TAPE.
5- USING A CLEAN & LINT FREE WIPE, CLEAN THE TWO SURFACES TO BE BONDED WITH A 50:50 MIXTURE OF ISOPROPYL
ALCOHOL (IPA) AND WATER. 70% IPA CAN ALSO BE USED.
ALLOW THE CLEANED SURFACES TO AIR DRY.
6- ONCE THE ADHESIVE BACKED ASSEMBLY IS PLACED APPLY PRESSURE VIA A SPRING CLAMP OR USE A WEIGHT TO
AID BOND STRENGTH.
AT 78°F / 26°C –AN UNDISTURBED SET TIME OF 24 HOURS WILL YIELD 90% OF THE TOTAL BOND STRENGTH
AND 72 HOURS FOR FULL BOND POTENTIAL.
