Fitment Notes & Exceptions

Notes from the manufacturer:

  • Intercom range will vary depending on obstacles (person, metal, wall, etc.) or electromagnetic environment.
  • Please make sure to take off your headset-installed helmet while charging. The headset automatically turns off during charging.
  • Any 3rd party USB charger can be used with HJC products if the charger is approved by either the FCC, CE, IC, KC, or other locally approved agencies.
  • Use of a non-approved charger may cause fire, explosion, leakage, and other hazards which may also reduce the life time or performance of the battery.
  • The headset is compatible with 5 V input USB-charged devices only.
  • If you pair your GPS device via GPS Pairing, its instruction will not interrupt your Intercom conversations, but overlay with them. Bluetooth intercom conversations will be interrupted by GPS instructions.
