Mounting Considerations
CAUTION
In high ambient temperatures and after extended use, the device enclosure may reach temperatures deemed
dangerous to touch. To avoid possible personal injury, the device must be installed in a location where it will
not be touched during operation.
NOTICE
This device should be mounted in a well-ventilated 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.
If you are mounting the device on fiberglass, when drilling the pilot holes, use a countersink bit to drill a
clearance counterbore through only the top gel-coat layer. This will help to avoid cracking in the gel-coat layer
when the screws are tightened.
When selecting a mounting location, observe these considerations:
• You must mount the device in a location that provides at least 25 mm (1 in.) of clearance on all sides to help
with proper ventilation.
• You must mount the device in a location that does not interfere with the fuel tank or electrical wiring.
• You must mount the device in a location where it is not exposed to fuel or fuel vapor.
• You must mount the device in a location with adequate ventilation where it is not exposed to extreme
temperatures.
• If you mount device in an enclosed space, you should install a cooling fan with appropriate ducts to aid in
airflow.
• You should mount the device so that the cables can be connected easily.
• To avoid interference with a magnetic compass, you should mount the device the specified distance away
from a compass. This distance is listed in the specifications section.
• You must not mount the device in close proximity to other navigation-critical equipment, antennas, or radio-
communication equipment on the vessel.
