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.
When selecting a mounting location, you should observe these
considerations.
• The location should provide optimal viewing as you operate
your boat.
• The location should allow for easy access to all device
interfaces, such as the keypad, touchscreen, and card
reader, if applicable.
• The location 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 location must allow room for the routing and connection
of all cables.
• The location must not be a flat, horizontal surface. The
location should be in a vertical angle.
The location and viewing angle should be tested before you
install the device. High viewing angles from above and below
the display may result in a poor image.
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.
The bail-mounting hardware (screws and washers, or nuts,
washers, and bolts) is not included. The bail mount bracket is
included in some models. Before you can bail mount the device,
you must purchase a bail mount bracket, if necessary. You must
also purchase mounting hardware that fits the holes in the bail
mount bracket and securely attaches it to your specific mounting
surface. The size of the pilot holes required depends on the
mounting hardware you purchase.
1
Using the bail mount bracket
À
as a template, mark the
location of the four pilot holes
Á
.
2
Using a drill bit appropriate for your mounting hardware, drill
the pilot holes.
3
Secure the bail mount bracket to the surface using your
mounting hardware
Â
.
4
Install the bail mount knobs
Ã
on the sides of the device.
5
Place the device in the bail mount bracket, and tighten the
bail mount knobs.
Flush 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.
The included template and hardware can be used to flush mount
the device in your dashboard. There are three options for
hardware based on the mounting surface material.
• You can drill pilot holes and use wood screws.
• You can drill holes and use nut plates and machine screws.
The nut plates can add stability to a thinner surface.
• You can punch and tap holes, and use machine screws.
1
Trim the template, and make sure it fits in the location where
you want to mount the device.
2
Secure the template to the mounting location.
3
Using a 13 mm (
1
/
2
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.
4
Using a jigsaw or a rotary tool, cut the mounting surface
along the inside line on the template.
5
Place the device in the cutout to test the fit.
6
If necessary, use a file and sandpaper to refine the size of
the cutout.
7
If necessary, remove the trim caps.
NOTICE
Use a plastic pry tool when possible. Using a metal pry tool,
such as a screwdriver, can damage the trim caps and the
device.
8
After the device fits correctly in the cutout, ensure the
mounting holes on the device line up with the larger holes on
the template.
9
If the mounting holes on the device do not line up, mark the
new hole locations.
10
Based on your mounting surface, drill or punch and tap the
larger holes:
• For wood screws, drill 3.2 mm (
1
/
8
in.) holes, and skip to
step 18.
• For nut plate and machine screws, drill 6 mm (
1
/
4
in.) holes
in the larger hole locations.
• For machine screws without the nut plate, punch and tap
M4 holes, and skip to step 18.
11
If you are using a nut plate, starting in one corner of the
template, place a nut plate
À
over the larger hole
Á
drilled in
the previous step.
The smaller hole
Â
on the nut plate should line up with the
smaller hole on the template.
12
If the smaller hole on the nut plate does not line up with the
smaller hole on the template, mark the new hole location.
