Warnings and Safety Notices
Antenna Mounting and EME Exposure
The VHF 300 series radio generates and radiates radio frequency (RF) electromagnetic energy (EME). Failure to observe these guidelines may
expose persons to RF radiation absorption exceeding the maximum permissible exposure (MPE).
Garmin declares an MPE radius of 59 in. (1.5 m) for this system, which was determined using 25 watts output to an omni-directional 9 dBi gain
antenna. The antenna should be installed such that a distance of 59 in. (1.5 m) is maintained between the antenna and all persons.
WARNING: Radio operators with cardiac pacemakers, life-support machines, or electrical medical equipment should not be exposed to excessive
radio-frequency elds.
WARNING: Operate the device in accordance with the instructions supplied.
CAUTION: Wear safety goggles and a dust mask when drilling, cutting, or sanding.
NOTICE: The device complies with internationally recognized standards covering human exposure to electromagnetic elds from radio devices.
NOTICE: Check with local authorities for any antenna or operational restrictions that may apply.
NOTICE: To prevent possible damage to your radio, the antenna must be connected to the radio before transmitting. This ensures that the power output
to the antenna port dissipates properly when transmitting.

Installing the Transceiver Box
Install the transceiver box below deck on a bulkhead, in a location that is dry and protected from washdown. Ensure that the location is
well ventilated and away from objects that generate heat. Ensure that the transceiver box is at least 20 in. (.5 m) from any compass to avoid
interference.
Mounting the Transceiver Box
1. Ensure that the chosen location is dry, protected, and well-ventilated.
2. Use the template on page 11 to determine mounting holes.
3. Drill four 1/8 in. (3 mm) pilot holes.*
4. Mount the transceiver box using the included M4.2×25 screws. You can also use bolts, washers, and nuts (not included) to mount the
transceiver box if the mounting surface allows.
Connecting the Transceiver Box to Power
Use the VHF 300 power/data cable to connect the transceiver box to a 12 Vdc battery through an external switch.
Notes:
Use the VHF 300 Power Wiring-Assignment Table to identify the positive and negative wires.
•
The replacement fuse on the power/data wiring harness is a 10 A, slow-blow
•
fuse.
•
If it is necessary to extend the power wires, use at least 16 AWG wire.
If your boat has an electrical system, you might be able to wire the radio
•
directly to an unused holder on your fuse block. If you use the fuse block,
remove the in-line fuse holder supplied with the power/data cable.

Installing the GHS 10 and Speaker
The GHS 10 connects to the transceiver box and to either the Garmin GHS 10 active speaker (included) or a passive speaker (not included).
When planning the GHS 10 installation, consider the following:
Per FCC law, you must install the GHS 10 in the wheelhouse or an adjacent room.
•
Install the GHS 10 and the active speaker at least 20 in. (.5 m) from any compass.
•
Install the active speaker within 48 in. (1.2 m) of the location you mount the bulkhead pass-through plate.
•
Consult the VHF 300 Series Layout Diagram on page 2 to determine how to connect the GHS 10 through a bulkhead to a speaker and to the
•
transceiver box.
If the cable is not long enough to reach the GHS 10 mounting location from the transceiver box, extension cables are available in lengths of
•
16 ft. (5 m) and 32 ft. (10 m). Install any extensions between the GHS 10 cable and the transceiver box according to the layout diagram on
page 2.
When you install the GHS 10 active speaker, if you use the GHS 10 cable to connect the active speaker to the transceiver box, do not
•
connect a passive speaker to the GHS 10 cable. Clip and tape the passive speaker wires.
Installing the GHS 10 Active Speaker
1. Use the GHS 10 active speaker Flush Mount Template to mount the active speaker. The template is self-adhesive.
2. Remove the paper backing from the template and adhere it to the bulkhead in a suitable location.
3. Use a 3 1/2 in. (90 mm) hole saw to cut the opening as indicated on the template.
4. Place the speaker in the cutout.
5. Ensure that the mounting screw locations align with
➋
the holes marked on the template. If they do not,
mark the locations of new pilot holes.
6. Drill four 1/8 in. (3 mm) pilot holes* in the correct
location.
7. Use the included M4.2×25 screws to mount the
active speaker.
8. Snap the cover plates on the active speaker.
9. To install the active speaker wiring harness to the
transceiver box, use the GHC 10 cable according to
the layout diagram on page 2.
Do not connect a passive speaker to the GHC 10
•
cable you use with the active speaker. Clip and tape the two passive speaker wires.
If the GHC 10 cable is not long enough to reach the transceiver box location, install an extension (not included) between the GHC 10
•
cable and the transceiver box as shown on the layout diagram on page 2.
10. To install the active speaker wiring harness though the bulkhead, follow the procedures on page 5.

Installing the Bulkhead Pass-Through Plate
1. Route the GHS 10 active speaker cable (or the GHS 10 cable) to the location you want to install the bulkhead pass-through plate.
2. Drill a 1 in. (25 mm) hole in the location at which you want to pass through the bulkhead.
3. Place the bulkhead pass-through plate over the hole and mark the three pilot-hole locations.
4. Drill the three 1/8 in. (3 mm) pilot holes.*
5. Connect the bulkhead pass-through plate to the bulkhead using the included M3.5 × 20 mm pan-head screws.
6. Remove the nut and connector cover from the GHS 10 cable (or the active speaker cable) and feed the connector through the bulkhead
pass-through plate.
7. Place the GHS 10 connector cover over the connector.
8. Use the nut to fasten the connector to the bulkhead pass-through plate.

Connecting the VHF 300 Series Radio to a Chartplotter (Optional)
You can connect the VHF 300 series radio to a chartplotter so that data such as DSC information can be displayed on the chartplotter.
Additionally, the radio can use location information from the GPS function of the chartplotter for position reports, and so forth.
You can connect the VHF 300 series radio to a NMEA 2000 network to access a NMEA 2000-compatible GPS antenna or chartplotter, or you
can wire the radio directly to a NMEA 0183-compliant chartplotter.
* A 1/8 in. (3 mm) pilot hole is nominal for plywood. Different dashboard materials my require a different size pilot hole.

Connecting the VHF 300 Series Radio to a NMEA 2000 Network
+
-
You can connect the VHF 300 series radio to your existing NMEA 2000 network, or you can build a basic NMEA 2000 network to connect to
another NMEA 2000-compatible device, such as a chartplotter. For more information on NMEA 2000 and to purchase required connectors, go
to www.garmin.com.
To connect the VHF 300 series radio to your existing NMEA 2000 network:
1. Determine where you would like to connect the radio to your existing NMEA 2000 backbone.
2. Disconnect one side of a NMEA 2000 T-connector from the backbone at an appropriate location.
If you need to extend the NMEA 2000 backbone, connect an appropriate NMEA 2000 backbone extension cable to the side of the
T-connector you disconnected.
3. Add a T-connector (not included) for the radio to the NMEA 2000 backbone by connecting it to the side of the T-connector you disconnected.
4. Route a NMEA 2000 drop cable (not included) to the bottom of the T-connector added in step 3 to your NMEA 2000 network. Use a drop
cable with a length up to 20 ft. (6 m).
5. Connect the drop cable to the T-connector and the NMEA 2000 port on the VHF 300 Series transceiver box.
NOTICE: If you have an existing NMEA 2000 network on your boat, it should already be connected to power. Do not connect an additional NMEA
2000 power cable to an existing NMEA 2000 network, because only one power source should be connected to a NMEA 2000 network.

2. Connect a NMEA 2000 power cable (not included) to one of the T-connectors.
NOTICE: A NMEA 2000 power cable must be connected to a 12 Vdc power source through a switch. The NMEA 2000 network may drain your
battery if it is connected directly. Connect the cable to the ignition switch of the boat if possible, or through an appropriate additional switch.
3. Connect a NMEA 2000 drop cable (not included) to the other T-connector and to the NMEA 2000 port on the VHF 300 Series transceiver
box.
4. Add additional T-connectors for each device you add to the NMEA 2000 network, and connect each device to a T-connector with a drop
cable.
5. Connect terminators (not included) to each end of the combined T-connectors.
Connecting the VHF 300 Series to a NMEA 0183 Device
The following diagram illustrates the NMEA 0183 wiring used to connect your VHF 300 series radio to a GPS chartplotter.
