• You can use the included 10 m (32 ft.) extension cable to
connect the active speaker to the VHF radio. You must select
a mounting location for the speaker where you can connect
the extension cable to the active speaker and to the GHS 11
STATION 1 port on the VHF radio. If needed, additional
extension cables are available from your Garmin dealer.
Mounting the Active Speaker
NOTICE
Be careful when cutting the hole to mount the speaker. 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 speaker after it is mounted.
Before you can mount the speaker, you must select a mounting
location.
1
Trim the template and make sure it fits at the mounting
location.
2
Secure the template to the mounting surface.
3
Using a 13 mm (
1
/
2
in.) drill bit, drill a hole inside the corner of
the line on the template to prepare the mounting surface for
cutting.
4
Using a rotary-cutting tool or jigsaw, cut the mounting surface
along the inside of the dashed line on the template.
5
Place the speaker in the cutout to test the fit.
6
If necessary, use a file and sandpaper to refine the size of
the cutout.
7
After the speaker fits correctly in the cutout, ensure the
mounting holes on the speaker line up with the pilot holes on
the template.
8
If the mounting holes on the speaker do not line up, mark the
new pilot-hole locations.
9
Using a 3 mm (
1
/
8
in.) drill bit, drill the pilot holes.
10
Remove the template from the mounting surface.
11
Install the included mounting gasket
À
on the back of the
speaker.
12
Make the necessary wiring connections (
Active Speaker to the VHF Radio and Handset
).
13
Place the speaker in the cutout.
14
Secure the speaker to the mounting surface using the
included M4 screws
Á
.
15
Snap the screw cover
Â
in place.
Installing the Handset Connector in the Mounting Surface
Before drilling a hole to mount the handset connector from the
active speaker, you should mount the active speaker and verify
that the cable from the active speaker is long enough to reach
the handset-connector mounting location (
).
If you do not install the active speaker, you must verify that the
included extension cable is long enough to connect to the GHS
11 STATION 1 port on the VHF radio and to the handset-
connector mounting location.
You can use the included hardware to mount the handset
connector from the active speaker on the dashboard or other
mounting surface. If you do not install the active speaker, you
can use the hardware to mount the handset connector from the
included extension cable on the dashboard or other mounting
surface.
1
Using the mounting plate
À
as a template, trace the cable
hole in the center of the mounting plate and mark the screw
locations.
2
Set the mounting plate aside.
Do not drill through the mounting plate.
3
Using a 22 mm (
7
/
8
in.) drill bit or hole saw, drill the center
cable hole
Á
in the mounting surface.
4
Using a 3 mm (
1
/
8
in.) drill bit, drill the pilot holes.
5
Apply marine sealant between the mounting plate and the
mounting surface to help seal the holes (optional).
6
Using the included screws, attach the mounting plate to the
mounting surface.
7
Select an option:
• If you installed the active speaker, route the long cable
from the active speaker to the connector mounting
location.
• If you did not install the active speaker, connect the
female end of the included extension cable to the GHS 11
STATION 1 port on the VHF radio, and route the male end
of the extension cable to the connector mounting location.
8
Feed the connector
Â
through the back of the mounting
surface.
9
Apply marine sealant around the connector in the mounting
plate to help seal the hole (optional).
10
Secure the connector to the mounting plate using the
weather cap
Ã
and the nut
Ä
.
GHS 11 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.
• You must install the primary handset (connected to the GHS
11 STATION 1 port) in the wheelhouse or an adjacent room,
in accordance with FCC law.
• To avoid interference with a magnetic compass, do not install
the handset closer than 60 cm (23.6 in.) to a compass.
• If you do not install the active speaker, you can use the
included 10 m (32 ft.) extension cable to connect the handset
to the VHF radio. You must select a mounting location for the
handset where you can connect the extension cable to the
handset and to the GHS 11 STATION 1 port on the VHF
radio. If needed, additional extension cables are available
from your Garmin dealer.
• You can use the included screws to mount the handset
connector and the handset cradle mount on your boat. If the
