• Select LOC to enable local sensitivity.
• Select DIST to enable distant sensitivity.
Switching Between 1 W and 25 W
Transmitting Modes
You can control the transmitting power of the radio. Low (1 W) is
used for local transmissions, and high (25 W) is used for
distance and distress transmissions.
When two signals broadcast on the same frequency, a VHF
radio receives only the stronger of the two signals. You should
transmit calls other than distress calls using the lowest power
setting that allows you to communicate, to reduce the possibility
that your transmissions interfere with the transmissions of
others.
In the USA frequency band, transmissions on channels 13 and
67 must be low (1 W) by default. You can bypass the power
setting temporarily during transmission (Bypassing the Low
Transmission Power Setting, page 2).
In the International channel band, transmissions on channels 15
and 17 must be low (1 W), and the radio does not allow
transmissions on these channels to be changed to high (25 W).
1Select HI/LO.
2Select 1W or 25W.
Using the Hailer
Before you can use the hailer function, you must provide and
install a hailer horn on your boat deck or tower (optional). For
more information, see the VHF 110/210 AIS Series Installation
Instructions.
The hailer allows you to make on-boat or ship-to-shore
announcements, and allows two-way communications between
connected radios. You can address the ship using the radio or
handset, and sounds received through the horn can be heard
through the radio speaker. For vessels with enclosed cabins, the
hailer allows you to hear sounds from the deck.
NOTE: Hailer functionality is not available on all VHF radio

Digital Selective Calling
Digital Selective Calling
NOTE: Before you can use DSC capabilities, you must enter a
Mobile Marine Safety Identity (MMSI) number (Entering Your
MMSI Number, page 4). An MMSI number identifies each
DSC radio, like a telephone number.
Digital Selective Calling (DSC) is a key component of the Global
Maritime Distress and Safety System (GMDSS). DSC enables
VHF radios to place and receive digital calls directly with other
vessels and shore stations, including the USA and Canadian
Coast Guards. Your radio includes full Class-D DSC capabilities.
If you have a GPS device connected to the transceiver, your
latitude, longitude, and the current time are transmitted when
you send a distress call or other type of DSC call. If you enter
your position information manually, your latitude, longitude, and
time of entry are transmitted with the call. Transmitting your
location automatically speeds help in an emergency situation.
Channel 70 is reserved exclusively for DSC calls, and your
device uses a dedicated receiver to maintain a constant watch
on Channel 70. You do not need to change the channel to make
a DSC call. Your device changes to Channel 70 automatically to
transmit a DSC call. Your radio sends the DSC data over
Channel 70 in less than one second, and then tunes to an
appropriate channel for voice communications.
appears on the device screen when you have an incoming or
missed DSC call.
NOTE: The device disables DSC automatically when you turn
on ATIS (Automatic Transmitter Identification System,
page 8).
Entering Your MMSI Number
NOTICE
You can enter your MMSI number only once. If you must change
your MMSI number after entering it, you must take your radio to
your Garmin® dealer for reprogramming.
The Mobile Marine Safety Identity (MMSI) number is a nine-digit
code that acts as a DSC self-identification number, and it is
required to use the DSC capabilities of your radio. You can
obtain an MMSI number from the telecommunications authority
or ship registry for your country. In the USA, you can obtain an
MMSI number from these sources:
• Federal Communications Commission (FCC): assignments
are recognized internationally
• BoatU.S.®, Sea Tow®, or United States Power Squadrons®:
assignments are for USA waters only.

1Select MENU > DSC > MY MMSI.
2Enter your MMSI number (Entering Text, page 4).
3Select ACCEPT.
The radio prompts you to confirm your identity.
4Enter your MMSI number again, and select ACCEPT.
If the MMSI numbers you entered do not match, a message
appears.
5If necessary, select RETRY, and enter the number again.
Viewing Your MMSI Number
Select MENU > DSC > MY MMSI.
Distress Calls
When you make a distress call, your call is transmitted to all
DSC-capable radios within receiving range. Your current GPS
position (latitude and longitude) and the current time are
included in the transmission if you have a GPS device
connected to your transceiver. If you manually entered your
position information with the time, that data is transmitted with
the call.
NOTE: You should familiarize yourself with the standard
distress-call format and protocol to ensure your calls are clear
and effective.
Sending an Undesignated Distress Call
When you send an undesignated distress call, the nature of your
emergency is not transmitted to the receiving stations. Sending
an undesignated distress call is a faster procedure that can save
you time during an emergency.

Automatic Transmitter Identification
System
Automatic Transmitter Identification System (ATIS) is a vessel
identification system used on certain inland waterways in some
European countries. See your Garmin dealer to program your
VHF radio if you plan to use your radio on waterways that are
within the bounds of the Regional Arrangement Concerning the
Radiotelephone Service on Inland Waterways (the Basel
Agreement). ATIS is prohibited outside the European inland
waterways that are covered by the Basel Agreement.
When you enable ATIS, your radio sends a data signal
identifying your station at the end of every transmission. Data
identifying your position is not sent, but your position is
calculated through the method of triangulation by coastal
stations that receive your transmissions.
To enable ATIS, you must enter your ATIS identification number
(Entering Your ATIS Identification Number, page 8), and turn
on ATIS (Turning On and Off ATIS, page 9). See your
Garmin dealer to determine your ATIS identification number and
to learn about ATIS requirements for your region.
Your radio disables these functions when you enable ATIS.
• Digital Selective Calling (DSC)
• Monitor two or three channels (Dual watch and Tri watch)
• Scanning channels
International channels 6, 8, 10, 11, 12, 13, 14, 71, 72, 74, and
77 restrict transmitting to low-power (1 W) when you enable
ATIS.
Entering Your ATIS Identification Number
NOTICE
You can enter your ATIS identification number only once. If you
must change your ATIS identification number after entering it,
you must take your radio to your Garmin dealer for
reprogramming.

Automatic Identification System
The Automatic Identification System (AIS) is an automatic
tracking system used on vessels and by vessel traffic services
(VTS). It enables vessels and VTS to identify and locate vessels
by electronically exchanging data with other nearby vessels and
AIS base stations. When used with a compatible chartplotter or
multifunction display (MFD), AIS can assist with collision
avoidance.
NOTE: AIS is not available on all models.
Turning On and Off AIS
1Select MENU > AIS.
2Select ON or OFF.
3Select OK.
NMEA 0183 and NMEA 2000®
When you connect the radio to a NMEA 0183 device or a NMEA
2000 network, you can transfer received DSC distress and
position information to any compatible connected chartplotter
(NMEA, page 16).
The radio can also receive GPS-position information from a
NMEA 0183 device or a NMEA 2000 network. Received GPS-
position information appears on the home screen and is
transmitted with DSC calls. appears on the screen when GPS
data is available, and flashes when GPS data is not present.
When GPS data is not present, you must enter your position
manually (Manual Position Information, page 8).
For more information on connecting the radio to a NMEA 0183
device or a NMEA 2000 network, see the VHF 110/210 AIS
Series Installation Instructions.
Additional Functionality with Other Garmin
Devices
The radio has additional capabilities when you connect it to
other Garmin devices, such as a chartplotter.
NOTE: You may need to upgrade your Garmin chartplotter
software to use NMEA 0183 or NMEA 2000 features.
When you connect the radio to a Garmin chartplotter using
either NMEA 0183 or NMEA 2000, your chartplotter keeps track
of the current and previous positions of the contacts in the
directory.
When you connect the radio to the same NMEA 2000 network
as a Garmin chartplotter, you can use the chartplotter to set up
an individual routine call.
When you connect the radio to the same NMEA 2000 network
as a Garmin chartplotter, and you initiate a man-overboard
distress call from the radio, the chartplotter prompts you to
navigate to the man-overboard location. If you connect a Garmin
autopilot system to the same NMEA 2000 network, the
chartplotter prompts you to start a Williamson's turn to the man-
overboard location.
Communicating Over NMEA 0183 or NMEA
2000
