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.

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 rst-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 7

Basic Operation

LOC

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 high-

trafc 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

1. Press the HI/LO key.

2. Select LOCAL/DIST to toggle between local and distant modes.

8 VHF 300 Series Owner’s Manual

icon is displayed on the screen when set to Local receiving sensitivity.

Basic Operation

Using the Intercom

The intercom is part of the Public Address (PA) system of your radio. You can use multiple
handset stations as an intercom system for two-way communication. Use the radio handset
to initiate communication with a remote handset station, and use a remote handset station to
initiate communication with the radio handset.

TIP: When the radio is in intercom mode, it does not receive trafc from your current

Using the Hailer

You must provide and install an optional hailer horn on the deck or tower to use the hailer
feature. See the VHF 300 Series Installation Instructions for installation information.

The hailer, which is part of the PA system of your radio, allows you to make on-boat or
ship-to-shore announcements. The hailer allows two-way communication; you can address
the ship using the handset, and sounds received through the horn can be heard through
the external speaker. For vessels with enclosed cabins, this allows you to hear what is
happening on deck.

NOTE: When the radio is in hailer mode, it does not receive trafc from your current

channel.

broadcasts on the WX channels are only available in the USA and certain regions in Canada.

There are 10 WX (weather) channels that are pre-programmed into your radio to monitor
weather broadcasts from the National Oceanic and Atmospheric Organization (NOAA). WX
channels are listen-only channels.

These broadcasts are in a continuous loop and are updated regularly. Because the NOAA
weather centers broadcasting the information are regional, the weather information will be
relevant to your broadcast area.

Automatic Transmitter Identication System

The Automatic Transmitter Identication System (ATIS) is a vessel identication 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 identication number (see below), and then turn on ATIS

(see page 13). Contact your Garmin dealer to determine your ATIS identication number
and to learn about ATIS requirements for your region.

Your radio disables the following functions when you enable ATIS:
