Scanning and Saving Channels
IMPORTANT: If you turn on ATIS, the radio cannot scan or save channels. See page 12.
Scanning All Channels
When you scan channels, the radio searches for channels that are broadcasting. If a channel
is broadcasting, the radio pauses on that channel until the broadcast stops. After four
seconds of inactivity on the channel, the radio resumes scanning.
1. Select SCAN > ALL.
2. Choose from the following options:
• SKIP—this option is displayed if active channels are detected. When you select
this option, the system resumes the scan and does not include that channel in
subsequent passes.
• +CH16—Channel 16 is scanned every other channel (for example: 21, 16, 22, 16,
and so on). “ALL SCAN +CH16” is displayed on the screen.
• -CH16—Channel 16 is scanned in its normal order (for example, 14, 15, 16, 17, and
so on). “ALL SCAN” is displayed on the screen.
• EXIT—returns you to Home screen. The system ends the current scan and continues
to receive on the channel where you ended the scan.
Saving Channels
You can save any channel other than the WX (weather) channels to the transceiver memory.
You can scan your saved channels separately from scanning all of the channels that radio
receives. There is no limit to the number of channels you can save.
To save a channel:
1. Select SCAN.
2. Turn the Channel knob to access different channels.
3. To save a channel, select SAV CH. A star on the top of the screen denotes a saved
channel.
VHF 300 Series Owner’s Manual

NOTE: This scan does not include Channel 16 unless you saved Channel 16 to memory.
However, you can select +CH16 to scan Channel 16 every other channel (for example: 21,
16, 32, 16). When this setting is active, the soft key displays -16. Select -CH16 to scan your
saved channels in their normal order (for example, 08, 10, 11, 14).
Repeating the Last Received Communication
When repeat is turned on, the radio records up to the last 90 seconds of the last received
transmission. When repeat is turned off, recording is disabled; the radio plays back the last
saved transmission from when repeat was on. During playback, the radio does not receive
transmissions on the current channel.
The radio will not save the beginning (less than one second) of each received transmission.
This prevents intermittent RF noise from overriding audio transmissions that have been
received and saved
To turn repeat on or off:
1. Select REPEAT. The radio plays back up to the last 90 seconds of the last received
transmission.
2. Select ON or OFF.
To repeat the last received transmission:
1. Select REPEAT. The radio plays back up to the last 90 seconds of the last received
transmission.
2. Select REPEAT again to play the message from the beginning.
Monitoring Multiple Channels
IMPORTANT: The radio disables multiple-channel monitoring (Dual watch and Tri watch)
if you turn on ATIS. See page 12.
Use the Watch feature to monitor priority channels and the currently selected channel for
broadcasting activity. Channel 16 is the first-priority channel on your radio. Channel 9 is the
default second-priority channel, but you can select another channel as your second-priority
channel. For more information on reprogramming the second-priority channel, see page 7.

VHF 300 Series Owner’s Manual
Basic Operation
Switching Between 1 W and 25 W Transmitting Modes
You can control the transmitting power of the radio. There are two options: LO (1 W) and
HI (25 W). LO is typically used for local transmissions, while HI is typically used for
distance and distress transmissions.
NOTE: When you press the 16/9 key (North American models) or the 16+ key
(International models), the radio switches to HI power. While in 16/9 mode, Channel 16
and the second-priority channel (Channel 9 by default) automatically transmit on HI power.
However, you can switch to LO power in 16/9 mode.
When two signals are broadcast on the same frequency, a VHF radio only receives the
stronger of the two signals. Other than distress calls, transmit using the lowest power
setting that allows you to communicate. This reduces the possibility of your transmissions
interfering with the transmissions of disinterested parties.
In the USA frequency band, transmissions on Channels 13 and 67 are required to be lowpower (1 watt) by default. You can bypass this power setting by pressing the 25W soft key
during transmission.
To switch between LO and HI transmitting power:
1. Press the HI/LO key.
2. Select 1W or 25W to toggle between LO and HI transmit power modes.
TIP: The radio returns to the Home screen automatically two seconds after changing the
1 W/25 W mode. You can also select OK to return to the Home screen.
Adjusting the Local/Distant Receiving Sensitivity
You can control the receiving sensitivity of the radio. If you are experiencing noise in hightraffic areas or areas with electromagnetic interference (caused by cell-phone towers, for
example), set the receiving sensitivity to Local to decrease the sensitivity of the receiver. In
remote areas and in open water, set the receiving sensitivity to Distant to ensure that you are
using the maximum range of the receiver.
The
LOC
icon is displayed on the screen when set to Local receiving sensitivity.
1. Press the HI/LO key.
2. Select LOCAL/DIST to toggle between local and distant modes.
VHF 300 Series Owner’s Manual

Automatic Transmitter Identification System
The Automatic Transmitter Identification System (ATIS) is a vessel identification system
that can be used on certain inland waterways in certain countries throughout Europe. Your
Garmin dealer can program your VHF 300i or VHF 300i AIS to use ATIS 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). The
use of ATIS is prohibited outside the European inland waterways covered by the Basel
Agreement.
When you enable ATIS, a data signal identifying your station is sent at the end of every
transmission. Data identifying your position is not sent; however, your position is calculated
through the method of triangulation by coastal stations receiving your transmissions.
To enable ATIS, enter your ATIS identification number (see below), and then turn on ATIS
(see page 13). Contact your Garmin dealer to determine your ATIS identification number
and to learn about ATIS requirements for your region.
Your radio disables the following functions when you enable ATIS:
• Digital Selective Calling (DSC)
• Dual watch and Tri watch
• Channel scanning
The following International channels are restricted to transmit on low-power (1 watt) when
you enable ATIS: 6, 8, 10, 11, 12, 13, 14, 71, 72, 74, and 77.

Digital Selective Calling
Digital Selective Calling
Digital Selective Calling (DSC) is a key component of the Global Maritime Distress and
Safety System (GMDSS). DSC provides VHF radios with the ability 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 and longitude and the
current time are transmitted when you send a distress call or other type of DSC call. If you
have manually entered your position information, your latitude, longitude, and time of entry
are transmitted with the call. Having your location automatically transmitted prevents you
from needing to identify your location in an emergency situation.
Channel 70 is reserved exclusively for DSC calls, and your radio 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, since your radio automatically changes to Channel 70 to transmit a DSC call.
Your radio sends the DSC data over Channel 70 in less than one second, and then tunes to
the appropriate channel for voice communications. The
icon is displayed when you
have an incoming or missed DSC call.
Important: To use the DSC capabilities of your radio, you must first enter a Mobile
Maritime Safety Identity (MMSI) number. An MMSI number identifies each DSC radio,
like a telephone number.
IMPORTANT: The radio disables DSC if you turn on ATIS. See page 12.
Entering Your MMSI Number
The Mobile Maritime Safety Identity (MMSI) number is a nine-digit code that acts as a
DSC self-identification number, and is required in order 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 the following
sources:
• Federal Communications Commission (FCC)—assignments are recognized
internationally
• BoatU.S., Sea Tow, or United States Power Squadrons®—assignments are for USA
waters only
After obtaining your MMSI number, you must program the number into your radio to
enable DSC.

DSC Distress Calls
When you make a DSC 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 have manually entered your position information with the time, that
data is transmitted with the call. For information on manually updating your position
information, see page 26.
NOTE: Familiarize yourself with the standard distress-call format and protocol to ensure
that 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 shorter and
quicker procedure that can save you time during an emergency.
1. Lift the spring-loaded door, and press and hold the DISTRESS key for at least three
seconds. The transceiver beeps, and the screen displays “DISTRESS CALL COUNTING
DOWN”. The channel pane counts down the seconds from 3 to 1.

Additional Functionality with Other Garmin Devices
Your VHF 300 series radio has additional capabilities when connected with other Garmin
devices.
NOTE: Your Garmin chartplotter may require a free software upgrade to use the
functionality listed in this section. Go to www.garmin.com for current updates to your
Garmin chartplotter software.
• When you connect your radio to a Garmin chartplotter using NMEA 0183 or
NMEA 2000, your chartplotter can keep track of the current and previous positions of
the contacts in the radio directory.
TIP: Try using position tracking on up to three contacts to automate this process.
• When your VHF 300 series radio is connected to a NMEA 2000 network with another
Garmin chartplotter, you can use the chartplotter interface to set up an individual routine
call.
• As an additional safety measure, when your VHF 300 series radio is connected to a
NMEA 2000 network and you initiate a man-overboard distress call from your radio,
your Garmin chartplotter displays the man-overboard screen and prompts you to navigate

MMSI (Vessel) Filtering over a NMEA Network
Your radio can send call-related data over NMEA 0183 or NMEA 2000 when it receives
distress calls, acknowledgements to position request calls, and other position-send calls. You
can filter the MMSI numbers (vessels) for which your radio sends this data in three ways:
any MMSI number (all vessels), no MMSI numbers (no vessels), or select MMSI numbers
(vessels selected from your directory).
When you configure the radio to send data for select vessels, and you receive an
acknowledgement to a position request call, or other position-send call from an MMSI
number not in your directory, your radio does not send NMEA data for that call. Distress
call information will still be sent. For more information about NMEA output from your
radio, see page 49.

Channel Lists
The USA, Canadian, and International channel lists provided in this Appendix are for
reference only. It is the responsibility of the radio operator to ensure that channels are used
correctly according to local regulations.
USA Channels
For the latest information on USA channels, visit www.navcen.uscg.gov/marcomms
/vhf.htm. Also visit the Federal Communications Commission’s Marine VHF Radio
Channels page at http://wireless.fcc.gov/services/index.htm?job=service
_bandplan&id=ship_stations. The FCC page does not include frequency information, but
has more complete information on the use of the channels.
IMPORTANT: Boaters primarily should use channels listed as non-commercial. Use
Channel 16 to call other stations or for distress alerting. Use Channel 13 to contact a ship
when there is danger of collision. All ships of length 20 m or greater are required to guard
VHF Channel 13, in addition to VHF Channel 16, when operating within USA territorial
waters. Users may be fined by the FCC for improper use of these channels.

Caring for the Unit
The case is constructed of high quality materials and does not require user maintenance, except cleaning.
Cleaning the Case
Clean the unit’s outer casing (except for the screen) using a cloth dampened with a mild detergent solution and
then wipe dry. Avoid chemical cleaners and solvents that may damage plastic components.
Cleaning the Screen
The unit’s lens is textured to reduce glare, and is sensitive to skin oils, waxes and abrasive cleaners. Cleaners
containing ammonia, alcohol, abrasives, or anti-grease detergents will harm the anti-reflective coating. It is
important to clean the lens using an eyeglass lens cleaner (that is specified as safe for anti-reflective coatings)
and a clean, lint-free cloth.
Water Immersion
The unit is waterproof to IEC Standard 60529 IPX7. It can withstand immersion in 1 meter of water for 30
minutes. Prolonged submersion can cause damage to the unit. After submersion, be certain to wipe and air dry
the unit before reuse.
