Warning and Known Issues
• It is important that the cable is installed fully onto the diagnostics port, and that the device is firmly attached to the vehicle.
Excessive vibrations from a loose installation can cause incorrect results.
• The 66xx beacons are not waterproof or sealed devices. Care must be taken to ensure the device is kept away from water or
any other liquids, as well as excessive dust.
• The 66xx beacons may be incompatible with certain models of vehicles. For more information please contact your Nero
dealer.
• The older external antennas that were previously shipped with the 3G beacons are not compatible with the newer 4G
devices. If you are upgrading a 3G beacon to a 6650 (4G) model, then the external antenna must also be upgraded to one of
the models described in this document.
• The 6681 beacon model does not support Bluetooth, and therefore cannot be used for ELD configurations.
• The 6681 beacon model does not support the J1708 protocol, and therefore will not function in vehicles that have the J1708
Deutsch (6-pin) diagnostics port. Please refer to Addendum A – Power/Data Cable Options.
