INSTRUCTIONS
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.
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.
Tools Needed
• Drill and drill bits
◦ 9 mm (3/8 in.) drill bit, to prepare the surface for cutting
◦ 2.5 mm (3/32 in.) drill bit, if using wood screws
◦ 3.5 mm (9/64 in.) drill bit, if using the nut plate
◦ 4 mm (5/32 in.) drill bit, if using the nut plate
• #2 Phillips screwdriver
• Jigsaw or rotary tool
• File and sandpaper
• Marine sealant (recommended)
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.
The mounting surface must be flat to avoid damaging the device
when it is mounted.
When selecting a mounting location, observe these
considerations.
• The mounting location should be at or below eye level to
provide optimal viewing as you operate your vessel.
• The mounting surface must be strong enough to support the
weight of the device and protect it from excessive vibration or
shock.
• To avoid interference with a magnetic compass, the device
should not be installed closer to a compass than the
compass-safe distance value listed in the product
specifications.
• The area behind the mounting surface must allow room for
the routing and connection of the cables.
The included template and hardware can be used to flush mount
the device in your dashboard. There are two options for
hardware based on the mounting surface material.
• You can drill pilot holes and use the included wood screws.
• You can drill holes and use the included nut plates and
machine screws. The nut plates can add stability to a thinner
surface.
Mounting the Device
NOTICE
Be careful when cutting the hole to flush mount the device.
There is only a small amount of clearance between the case and
the mounting holes, and cutting the hole too large could
compromise the stability of the device after it is mounted.
To avoid potential damage to the device, use only the included
screws to mount it. Using screws other than the ones included
will void your warranty.

1Trim the template and make sure it fits in the location where
you want to mount the device.
2Secure the template to the selected location.
3Using a 9 mm (3/8 in.) drill bit, drill one or more of the holes
inside the corners of the solid line on the template to prepare
the mounting surface for cutting.
4Using a jigsaw or rotary tool, cut the mounting surface along
the inside of the solid line indicated on the template.
5Place the device in the cutout to test the fit.
6If necessary, use a file and sandpaper to refine the size of
the cutout.
7After the device fits correctly in the cutout, ensure the
mounting holes on the device line up with the holes on the
template.
8If the mounting holes on the device do not line up, mark the
new hole locations.
9Based on your mounting method, drill the outer holes on the
template:
• Drill 2.5 mm (3/32 in.) pilot holes for the included wood
screws, and skip to step 18.
• Drill 3.5 mm (9/64 in.) holes for the included nut plate and
machine screws.
10If using the nut plates, starting in one corner of the template,
place a nut plate over the hole drilled in the previous
step.
