• The unit can be mounted on a vertical surface such as a bulkhead or mast etc, using the supplied
bulkhead bracket.
• Do NOT mount on top of a mast.
• The unit location must be at least 1 m (3 ft.) away from any source of magnetic interference, such
as compasses and electrical cables.
• Choose a location where the unit will be safe from physical damage and excessive vibration.
• Choose a location where the unit will not be subjected to a load or force.
• Mount away from any source of heat or potential flammable hazards, such as fuel vapor.
• The unit should be mounted in a location where the diagnostics LED is viewable.
• The unit must be mounted with the LED 'arrow' on the top of the unit pointing forwards, in parallel

RF interference

Certain third-party external electrical equipment can cause Radio Frequency (RF) interference with
GNSS (GPS), AIS or VHF devices, if the external equipment is not adequately insulated and emits
excessive levels of electromagnetic interference (EMI).
Some common examples of such external equipment include LED lighting (e.g.: navigation lights,
searchlights and floodlights, interior and exterior lights) and terrestrial TV tuners.
To minimize interference from such equipment:
• Keep it as far away from GNSS (GPS), AIS or VHF products and their antennas as possible.
