Garmin 18 Manuale Utente

• The radome has two mounting options when installed on a

standard marine mount. One mounting option is closer to the

center of the radome

, and the second option is offset

towards the back

to move the radar further away from the

mast.

• The device should be mounted away from heat sources such

as smoke stacks and lights.

• The device should be mounted at a different level than

horizontal spreaders and mast crosstrees.

• To avoid interference with a magnetic compass, the device

should not be mounted closer to a compass than the

compass-safe distance value listed in the product

specifications.

• Other electronics and cables should be mounted more than

2 m (6 ½ ft.) from the radar beam path.

• GPS antennas should be either above or below the radar

beam path.

• The device should be mounted at least 1 m (40 in.) from any

transmitting equipment.

• The device should be mounted at least 1 m (40 in.) away

from cables carrying radio signals such as VHF radios,

cables, and antennas.
For Single Side Band (SSB) radios, increase the distance to

2 m (6 ½ ft.).

Cable Considerations

It may be necessary to drill 31.7 mm (1 ¼ in.) holes for routing

the power or network cable. The provided rubber cable

grommet can be used to cover a cable installation hole.
• The grommet does NOT provide a waterproof seal. To make

the grommet waterproof, marine sealant must be applied.

• Additional cable grommets can be purchased from Garmin or

a Garmin dealer.

When installing the power and network cables, you should

observe these considerations.
• Cutting the Garmin Marine Network cable is not

recommended, but a field install kit can be purchased from

Garmin or a Garmin dealer if cutting the network cable is

necessary.

• To ensure safety, appropriate tie-wraps, fasteners, and

sealant should be used to secure the cable along the route

and through any bulkheads or the deck.

• Cables should not be run near moving objects and high-heat

sources or through doorways and bilges.

• To avoid interference with other equipment, power and

network cables should not be run next to or parallel to other

cables, such as radio antenna lines or power cables. If this is

not possible, the cables should be shielded with metal

conduit or a form of EMI shielding.

• The power cable should be installed as close to the battery

source as possible.

◦ If is necessary to extend the power cable, the appropriate

gauge of wire must be used as directed in these

instructions.

◦ Incorrectly extended runs of cable may cause the radar to

malfunction due to insufficient power transmission.

Mounting the Radar

Before you mount the radar, you must review the mounting

location considerations and select a mounting location.
NOTE: The supplied M8 x 1.25 x 60 threaded rods can be used

on mounting thicknesses of 5 to 30 mm (

to 1

in.)

(recommended). For surfaces over 30 mm (1

in.), use

longer threaded rods.

If you are not installing the device on a pre-drilled Garmin-

compatible radar mount, use the included mounting template

to drill four 9.5 mm (

in.) mounting holes.

Install the locking ring and o-ring on the end of the Garmin

Marine Network cable.

Connect the power cable to the power port

and the

network cable to the network port

Press the cables into any of the guide grooves

on the

bottom of the case, and secure them using a cable hold-

down plate

The cables should be bent or twisted as little as possible.

Position the radome on the mounting surface with the

triangular mark on the case aligned to the front of the vessel.

Apply the included anti-seize compound to the threads of the

four M8 x 1.25 x 60 threaded rods.

Insert the four threaded rods into the mounting holes on the

bottom of the radome.
Up to 50 mm (2 in.) of the threaded rods may extend below

the radome.

Apply a bead of marine sealant on the mounting surface

around each mounting hole.

Fasten the radome

to the mounting surface

using the

threaded rods

, flat washers

, spring washers

, and hex

nuts
