Mounting Considerations
CAUTION
In high ambient temperatures and after extended use, the device enclosure may reach temperatures deemed
dangerous to touch. Therefore the device must be installed in a location where it will not be touched during
operation.
NOTICE
This device should be mounted in a location that is not exposed to extreme temperatures or conditions. The
temperature range for this device is listed in the product specifications. Extended exposure to temperatures
exceeding the specified temperature range, in storage or operating conditions, may cause device failure.
Extreme-temperature-induced damage and related consequences are not covered by the warranty.
This device is designed for installation only in a dry location. Installing this device in a location where it may
come in contact with water or become submerged may result in damage. Water damage is not covered by the
warranty.
• The device must be mounted in a location that does not interfere with the fuel tank or electrical wiring.
• The device must be mounted in a location where it is not exposed to water.
• The device must be mounted in a location with adequate ventilation where it is not exposed to extreme
temperatures.
• If the device is mounted in an enclosed space, you should install a cooling fan with appropriate ducts to aid in
airflow.
• The device should be mounted so that the cables can be connected easily.
• To avoid interference with a magnetic compass, the device should be installed at least 50 cm (20 in.) away
from a compass.
• The device should not be mounted in close proximity to other navigation-critical equipment, antennas, or
radio-communication equipment on the vessel.
