“TRI WATCH CH: 75 + 16 + 9”.

3. To exit Tri watch, select EXIT.

Reprogramming the Second-Priority Channel

You can program your radio to recognize a channel other than Channel 9 as your second­priority channel.

1. Select MENU.

2. Select CHANNEL > 2ND PRIORITY.

3. Turn the Channel knob or use the up and down arrows on the microphone or handset to
change the channel displayed on the screen.

4. When the correct channel is displayed, select OK.

Using 16/9 Mode

16/9 is a priority operation that is activated by pressing the 16/9 key on the transceiver or
the microphone. Pressing the 16/9 key stops the current operation and changes your current

working channel to Channel 16 on the rst press, your second-priority channel on the

second press, and your original channel on the third press. Entering this mode changes the
transmit power to HI (25 W), and leaving this mode restores the previous setting.

1. Press the 16/9 key to immediately switch to Channel 16 and change the transmit power
to HI (25 W). To transmit on LO power in 16/9 mode, press the HI/LO key, and then
select 1W. The radio displays 1W on the screen to indicate low-power transmission.

2. Press the 16/9 key again to switch to your second-priority channel.

3. Press the 16/9 key a third time to return to your previous current working channel and
the previous transmit power setting.

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, 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.

190-01019-00_0A.indd 8 12/23/2008 4:23:02 PM

VHF 100/200 Series Owner’s Manual 9

Basic Operation

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

LOCAL

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.

Using the Intercom

Intercom operation only applies to the VHF 200 series radios and GHS 10 series handsets.

The intercom is part of the Public Address (PA) system of your radio. With an optional
GHS 10 or GHS 10i handset, you can use the radio and handset stations as an intercom
system for two-way communication. You can use the radio to initiate communication with a
handset station, and you can use a handset to initiate communication with the radio.

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

Initiating an Intercom Call

1. Select PA > INTRCM.

2. Select a device from the list. Selecting ALL will transmit to every station. The other party
must press the PTT key on the receiving unit to accept the call.

3. Press and hold the PTT key and speak your message.

optional hailer horn on the deck or tower to use this feature. See the VHF 100/200 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 for two-way communication: 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, 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.

To operate the hailer:

1. Select PA > HAILER. Sounds received through the horn can be heard through the radio
speaker.

2. Press and hold the PTT key and speak your announcement.

3. Turn the Channel knob or select the up and down arrows to adjust the horn volume.

4. Release the PTT key to listen.

Adjusting the Sound Frequency of the Foghorn

You can increase or decrease the sound frequency of the foghorn. The pitch of the tone
will rise with an increase in the frequency, and will fall with a decrease in frequency. The
minimum setting is 200 Hz and the maximum setting is 850 Hz. The default setting is 350
Hz. Regulations dictate the correct frequency of foghorns. Typically, these regulations
correlate the required foghorn frequency with the size of the vessel.

Listening to NOAA Weather Broadcasts and Enabling Weather Alerts

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.

NOTE: This functionality is not available with the VHF 100i or VHF 200i. NOAA broadcasts

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

Accessing WX (Weather) Mode

1. While viewing the Home screen, press the Channel knob. “WX” is displayed to indicate
that you are listening to WX frequencies.

2. Turn the Channel knob to change the channel.

3. Select EXIT to return to the Home screen. The radio returns to the channel you were
listening to before you entered WX mode.

Enabling WX (Weather) Alerts

You can enable your radio to continually monitor NOAA weather alerts. If the radio detects
an incoming weather alert, it will automatically tune to the WX channel that is broadcasting
the alert. The radio will not receive WX alerts if the transmitter is active.

NOTE: When you enable weather alerts, the radio only monitors the last monitored weather

channel.

1. Press the Channel knob to access WX mode.

2. Select ALERT.

3. Select EXIT or press the Channel knob to return to the Home screen.

The icon indicates that WX alerts are enabled.

Disabling WX (Weather) Alerts

1. Press the Channel knob to access WX mode.

2. Select ALERT.

3. Select EXIT to return to the Home screen.

Automatic Transmitter Identication System (ATIS)

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 100i,
VHF 200i, or GHS 10i 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 14). 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:

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.

Entering Your ATIS Identication Number

1. Press the MENU key.

2. Select ATIS > MY ATIS ID.

3. For each number in the sequence, turn the Channel knob clockwise to increase the
number, and counterclockwise to decrease the number.

4. Press the Channel knob to accept the number and move to the next number in the
sequence.

5. Select ACCEPT when you have entered your ATIS number. The radio prompts you
reenter your number.

6. Enter your ATIS ID number again, and press ACCEPT. If the ATIS ID numbers you
entered do not match, the screen displays “ATIS ID NUMBERS DO NOT MATCH”.
Select RETRY and enter the numbers again.
