GPS/GNSS location requirements

Your product includes a built in GPS/GNSS antenna. Ensure you consider the following before
choosing a location for you product:
Mounting location
It is recommended that the product is installed above decks as this will provide optimal GPS/GNSS
performance. Below decks installation may impact GPS/GNSS performance.
Vessel construction
The construction of your vessel can have an impact on GPS/GNSS performance. For example, the
proximity of heavy structures such as bulkheads, may result in a reduced GPS/GNSS signal.
Prevailing conditions
Weather conditions and the geographic location of the vessel can effect GPS/GNSS performance.
Typically calm clear conditions provide a more accurate position fix. Vessels at extreme northerly or
southerly latitudes may also receive a weaker GPS/GNSS signal. Product mounted below decks will
be more susceptible to performance issues related to the prevailing conditions.

Wireless location requirements

A number of factors can influence wireless performance. It is important to ensure you test the
connection performance at the desired location before installing wireless-enabled products.
Distance
The distance between wireless products should always be kept to a minimum. Do not exceed the
maximum stated range of your wireless product (maximum range will vary for each device).
Wireless performance degrades over distance, so products farther away will receive less network
bandwidth. Products installed close to their maximum wireless range may experience slow
connection speeds, signal dropouts, or not being able to connect at all.
Line of sight
For best results the wireless product should have a clear, direct line of sight to the product it will be
connected to. Any physical obstructions can degrade or even block the wireless signal.
The construction of your vessel can also have an impact on wireless performance. For example, metal
structural bulkheads and roofing will reduce — and in certain situations — block the wireless signal.
If the wireless signal passes through a bulkhead containing power cables this can also degrade
wireless performance.
Reflective surfaces such as metal surfaces, some types of glass and even mirrors can drastically
affect performance or even block the wireless signal.
Interference and other equipment
Wireless products should be installed at least 1m (3 ft) away from:
• Other wireless-enabled products.
• Transmitting products that send wireless signals in the same frequency range.
• Other electrical, electronic or electromagnetic equipment that may generate interference.
Interference from other people's wireless devices can also cause interference with your products.
You can use a third-party wireless analyzer tool / smartphone app to assess the best wireless channel
to use (e.g. a channel not in use or one used by the least number of devices).

EMC installation guidelines

Raymarine equipment and accessories conform to the appropriate Electromagnetic Compatibility
(EMC) regulations, to minimize electromagnetic interference between equipment and minimize the
effect such interference could have on the performance of your system
Correct installation is required to ensure that EMC performance is not compromised.
Note: In areas of extreme EMC interference, some slight interference may be noticed on the
product. Where this occurs the product and the source of the interference should be separated
by a greater distance.
For optimum EMC performance we recommend that wherever possible:
