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

as a template, mark

the location of the four pilot holes

Using a drill bit appropriate for your mounting hardware, drill

the pilot holes.

Secure the bail mount bracket to the surface using your

mounting hardware

Install the bail mount knobs

on the sides of the device.

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.

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

you want to mount the device.

Secure the template to the selected location.

Using a 13 mm (

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.

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

along the inside line on the template.

Place the device in the cutout to test the fit.

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

the cutout.

After the device fits correctly in the cutout, ensure the

mounting holes on the device line up with the larger 7.2 mm

(

in.) holes on the template.

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

new hole locations.

Using a 7.2 mm (

in.) drill bit, drill the larger holes.

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

over the larger hole

drilled in step 9.

The smaller 3.5 mm (

in.) hole

on the nut plate should

line up with the smaller hole on the template.

If the smaller 3.5 mm (

in.) hole on the nut plate does not

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

nut plates and holes on the template.

Using a 3.5 mm (

in.) drill bit, drill the smaller holes.

Remove the template from the mounting surface.

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

plate

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.

Secure the nut plate to the mounting surface by fastening an

included M3 screw

through the smaller 3.5 mm (

in.)

hole.

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

mounting surface.

Install the rubber gasket

on the back of the device.

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

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

device to properly seal and prevent leakage behind the

dashboard.
