Important Safety Information
WARNING
Failure to follow these warnings, cautions, and notices could
result in personal injury, damage to the vessel or device, or poor
product performance.
See the
Important Safety and Product Information
guide in the
product box for product warnings and other important
information.
When connecting the power cable, do not remove the in-line
fuse holder. To prevent the possibility of injury or product
damage caused by fire or overheating, the appropriate fuse
must be in place as indicated in the product specifications. In
addition, connecting the power cable without the appropriate
fuse in place voids the product warranty.
CAUTION
To avoid possible personal injury, always wear safety goggles,
ear protection, and a dust mask when drilling, cutting, or
sanding.
To avoid possible personal injury or damage to the device and
vessel, disconnect the vessel's power supply before beginning
to install the device.
To avoid possible personal injury or damage to the device or
vessel, before applying power to the device, make sure that it
has been properly grounded, following the instructions in the
guide.
NOTICE
For the best possible performance, the device must be installed
according to these instructions.
When drilling or cutting, always check what is on the opposite
side of the surface to avoid damaging the vessel.

Mounting Considerations
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.
You can flush mount the device in the dashboard, or bail mount
the device on the dashboard.
When selecting a mounting location, observe these
considerations.
• You should mount the device to provide an optimal viewing
angle as you operate your boat.
• You must select a location that is strong enough to support
the weight of the device and protect it from excessive
vibration or shock.
• To avoid interference with a magnetic compass, you must not
mount the device closer to a compass than the compass-safe
distance value listed in the product specifications.
• You must select a location that allows room for the routing
and connection of all cables.
• You should select a location that allows for easy access to
the device touchscreen.
• You should select a location that allows for access to the
microSD
®
card in the back of the device. If the location does
not allow access, you must insert the memory cards before
installing the device.
Bail Mounting the Device
NOTICE
If you are mounting the bracket on fiberglass with screws, it is
recommended to 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.
