Setup and Installation
Follow these steps to properly install the BT40 headset into your helmet:
- Prepare Earphones: Take the helmet headphones from the box. Attach the "Magic Tape" (Velcro adhesive pads) to the back of both earphones.
- Position Earphones: Remove the protective tape paper from the Velcro on the earphones. Carefully position and stick the earphones into the helmet's ear recesses on both sides. Ensure proper alignment before pressing firmly.
- Secure Headset: Once the Velcro is attached to the helmet, secure the headset earphones to these Velcro pads.
- Microphone Placement: Position the microphone arm so that the microphone is close to your mouth for clear communication.
- Final Check: Ensure all components are securely attached and comfortable within the helmet.
Important Note: Before ordering, please check the inner size of your helmet to ensure a comfortable fit for the headset. The headset's ultra-thin design (0.35 inches) is suitable for most helmets without causing discomfort.
