The A19 unit can be attached to your helmet using either the Clamp Base or the Paste Base. Select the method that best suits your helmet type and preference.

• Clamp Base: Ideal for helmets with an edge where the clamp can securely grip.
• Paste Base: Suitable for helmets without a suitable edge for clamping, using adhesive for attachment.

2. Installing the Main Unit

1. Clean the Surface: Ensure the helmet surface where the unit will be mounted is clean and dry.
2. Attach Base:
   • For Clamp Base: Loosen the screws, position the clamp on the helmet's lower edge, and tighten the screws securely.
   • For Paste Base: Remove the protective film from the adhesive, carefully align the base, and press firmly onto the helmet surface for at least 30 seconds. Allow adhesive to cure for several hours before use.
3. Mount A19 Unit: Slide the A19 host unit onto the installed base until it clicks into place.

3. Installing Speakers and Microphone

1. Remove Helmet Liner: Carefully remove the helmet's inner liner and cheek pads to access the interior shell.
2. Position Speakers: Identify suitable flat areas inside the helmet, near your ears, for speaker placement. Use the provided Horn Velcro (soft side) on the speakers and the Hard Soft Mac Velcro (hard side) on the helmet interior. Ensure speakers are centered over your ears for optimal sound.
3. Position Microphone: Attach the microphone to the inside of the helmet, near your mouth. Ensure it is positioned to pick up your voice clearly without being obstructed or causing discomfort. The microphone comes with a windproof sponge for improved call clarity.
4. Route Cables: Carefully route all speaker and microphone cables under the helmet liner and padding to conceal them and prevent interference with comfort or safety. Connect the speaker/microphone cable to the earphone jack on the A19 main unit.
5. Reinstall Liner: Reinstall the helmet liner and cheek pads, ensuring no cables are pinched or exposed.
