• Connectivity Issues/Cannot Pair:
  • Perform a "Clear Pairing Data" operation as described in Section 3.3 and Video 3.1. This clears all previous pairings and allows for a fresh connection attempt.
  • Ensure both devices are in pairing mode.
  • Move closer to the device you are trying to pair with to rule out range issues.
• Static or Poor Audio Quality:
  • Check all wire connections to ensure they are secure and not damaged, bent, or pinched.
  • Verify speaker placement within the helmet; they should be aligned with your ears.
  • Ensure the microphone is positioned correctly and not obstructed.

  • The unit features dual noise filtering (microphone and DSP); ensure no external factors are interfering with this system.
• Short Battery Life:
  • Ensure you are using a standard 5V charger, not a fast charger.
  • Avoid leaving the unit completely drained for extended periods.
