Important Safety Information

WARNING

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

Always wear safety goggles, ear protection, and a dust mask
when drilling, cutting, or sanding.

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.

Using the included hardware and template, you can mount the
device using one of two methods. You can use the included
bracket and hardware to bail mount the device, or you can use
the included template and hardware to flush mount the device in
the dashboard.

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

March 2015

Printed in Taiwan 190-01841-03_0B

compass-safe distance value listed in the product
specifications.

• The location must allow room for the routing and connection
of all cables.

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 any 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. Before you can bail mount
the device, you must choose 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 choose.

Using the included bail mount bracket À as a template, mark

1

the location of the four pilot holes Á.

After the device fits correctly in the cutout, ensure the

7

mounting holes on the device line up with the larger 7.2 mm
(5/16 in.) holes on the template.

If the mounting holes on the device do not line up, mark the

8

new hole locations.
Using a 7.2 mm (5/16 in.) drill bit, drill the larger holes.

9

Starting in one corner of the template, place a nut plate

10

over the larger hole Á drilled in step 9.

The smaller 3.5 mm (1/8 in.) hole  on the nut plate should
line up with the smaller hole on the template.

If the smaller 3.5 mm (1/8 in.) hole on the nut plate does not

11

line up with the smaller hole on the template, mark the new
hole location.

Repeat steps 10 and 11 to verify placement of the remaining

12

nut plates and holes on the template.
Using a 3.5 mm (1/8 in.) drill bit, drill the smaller holes.

13

Remove the template from the mounting surface.

14

Starting in one corner of the mounting location, place a nut

15

plate à on the back of the mounting surface, lining up the
large and small holes.

The raised portion of the nut plate should fit into the larger
hole.

À

Using a drill bit appropriate for your mounting hardware, drill

2

the pilot holes.
Secure the bail mount bracket to the surface using your

3

mounting hardware Â.
Install the bail mount knobs à on the sides of the device.

4

Place the device in the bail mount bracket, and tighten the

5

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.

Trim the template, and make sure it fits in the location where

1

you want to mount the device.
Secure the template to the selected location.

2

Using a 13 mm (1/2 in.) drill bit, drill one or more of the holes

3

inside the corners of the solid line on the template to prepare
the mounting surface for cutting.

Using a jigsaw or a rotary tool, cut the mounting surface

4

along the inside line on the template.
Place the device in the cutout to test the fit.

5

If necessary, use a file and sandpaper to refine the size of

6

the cutout.

Secure the nut plate to the mounting surface by fastening an

16

included M3 screw Ä through the smaller 3.5 mm (1/8 in.)
hole.

Repeat steps 15–16 to secure the remaining nut plates to the

17

mounting surface.
Install the rubber gasket Å on the back of the device.

18

The pieces of the rubber gasket have adhesive on the back.
Make sure you remove the protective liner before installing
them on the device.

If you will not have access to the back of the device after you

19

mount it, connect all necessary cables to the device before
placing it into the cutout.

NOTE: To prevent corrosion of the metal contacts, cover
unused connectors with the attached weather caps.

Apply marine sealant between the mounting surface and the

20

device to properly seal and prevent leakage behind the
dashboard.
