Radio Licenses:
1. Ship Station License
An FCC ship station license is no longer
required for any vessel traveling in US
waters which uses a VHF marine radio,
RADAR, EPIRB, and which is not
required to carry radio equipment. A
license is necessary however for a DSC
MMSI number, or for any vessel required
to carry a marine radio on an international
voyage, carrying a HF single side band
radiotelephone or marine satellite termi-
nal. For more information, see the FCC’s
Fact Sheet PR 5000 #14. FCC license
forms, including applications for ship
(506) and land station licenses can be
downloaded via the Internet at
www.fcc.gov/forms. To obtain a form
from the FCC, call (888) 225-5322.
2. Radio Call Sign

5. Channel Descriptions
The Radio Status Display indicates the
type of channel you have selected with
both a long and a short description. (Fig.
5) The long description will scroll from
right to left, and will be replaced by a
shorter description that stays in the Radio
Status Display. There is no universal
agreement on how to describe each chan-
nel, and some channels have different
purposes depending on where you’re
located in the US, but we’ve done our
best to provide helpful information. See
the appendix for a complete list of long
and short channel descriptions (pp. 20-23)
•Channels used by recreational boaters
for ship to ship conversations are list-
ed as NON-COMMERCIAL in the
description. Examples are Channels
68, 69, 71, and 72.
6. Changing Between
USA, International,
and Canadian Modes
Different areas of the world use different
VHF frequencies, although the channel
designation (1–88) may be the same.
There are three modes: USA,
International, and Canadian. Press and
hold the UIC key for two seconds to
change from USA to International to
Canadian Modes in turn.
•When Country Mode is changed,
Channel 16 is automatically selected,
not the last channel used. (Fig.
6a–6c)
•The Radio Status Display will verify
your selection with SEL USA, SEL
INTERNATIONAL, and SEL
CANADIAN.

7. Adjusting the
Squelch
The Squelch Control reduces the static
and noise heard on the radio, but allows
strong signals to be heard clearly. To
adjust the squelch setting, press the
SQL/UIC key quickly. The Radio Status
Display will show SQL - 0X, where Xis
the current squelch setting. (Fig. 7a) Press
the ▲or ▼keys to adjust the squelch set-
ting from 00 to 08. Higher settings allow
only stronger signals will be heard, while
lower settings allow weak signals to be
received (and possibly annoying static).
Generally, the squelch control should be
set for the lowest setting that eliminates
unwanted static.
•Level 00 allows all signals to be
heard.
•After no buttons are pressed for 3
seconds, the radio will return to nor-
mal receiving mode and the Radio
Status Display will show SQUELCH
LEVEL CHANGED. (Fig. 7b)

8. Transmitting a Signal
To transmit a signal, press the Push-To-
Talk (PTT) button on the left side of the
radio. When PTT button is released, the
radio returns to Receive Mode.
•As soon as the PTT key is pressed,
the Radio Status Display will show
the transmit power selected. (Fig. 8a)
Seafit V20 Radio Owner’s Manual 7
Fig. 9a: High Power Display
•When the PTT key is released, the
Radio Status Display will show TX
END (Fig. 8b)
•You cannot transmit on receive-only
channels like the weather channels or
Channels 15 and 70. If you try, an
error tone will sound, the channel
number and TX indicator will blink
three times and the Radio Status
Display will show REC ONLY (Fig
8c). After 3 seconds, the radio returns
to the normal display, then goes back
to the normal display.
•If the PTT button is pressed when
the battery condition is low, the radio
will send one last transmission, then
it will sound the Error Beep Tone
with BAT LO display. No further
transmission will be allowed. See
page 8.
9. Selecting the
Transmit Power
By law, Marine VHF radios must be able
to transmit at 1 watt power as well as the
radio’s maximum transmit power. The
Seafit V20 radio actually has three trans-
mit powers: 5 watts (HI), 1 watt (MED),
and 0.5 watts (LOW).
The general rule is to use the lowest
transmit power that results in clear com-
munications with whomever you are com-
municating. At distances less than a mile,
for example, 0.5 watts may result in clear
and consistent communications, and will
have the benefit of greatly extended bat-
tery life.
Pressing the H/L key will change the
transmit power from 5 watts (HI) to 1
watt (MED) to 0.5 watts (LOW) and back
to 5 watts with each press. The Radio
Status Display will indicate the newly
selected transmit power as follows:
•When High Power is selected, the
bottom of the screen will Radio

Fig. 9c: Low Power Display
Status Display will show XMIT HI
for three seconds. (Fig. 9a)
•When Medium Power is selected, the
Radio Status Display will show
XMIT MED for three seconds and the
Mindicator will show. (Fig. 9b)
•When Low Power is selected, the
Radio Status Display will show
XMIT LOW for three seconds and
the Lindicator will show. (Fig. 9c)
Certain channels are limited by law to 1
watt transmit power: USA Mode Channel
13, 17, 67, 77; INT Mode Channel 15, 17;
CAN Mode Channel 13, 15, 17, 20, 66,
77. Therefore, the radio will automatically
select 1 watt power when operating on
these channels, and efforts to change the
transmit power will result in the error tone.
•You cannot change the transmit
power setting on channels which are
receive-only channels: all weather
channels; USA Mode Channel 15,
70; INT Mode Channel 70; CAN
Mode Channel 70.
•Pressing the H/L key while scanning
or while in the Weather Mode will
result in the error tone and transmit
power will not change.
10. Battery Level Display
The battery level is checked periodically
and is shown using the Battery Level
Indicator (1–3 bars). More bars indicate
more battery capacity is left.
•When the battery capacity is very
low, the low battery warning alarm
will sound every 10 seconds, the low
battery message LOW BATT will be
shown on the Radio Status Display,
and the battery indicator will blink.
(Fig. 10)
•When the low battery warning mes-
sage is displayed, the radio allows
one final transmission but it will not
allow further transmissions.

Fig. 11b: Marine Mode Display
11. Weather Mode
Virtually all areas of the US and many
areas around the world are covered by
VHF weather reports on one of 10 chan-
nels. These reports provide current condi-
tions, forecasts, and warnings of danger-
ous weather 24 hours per day.
Press and release the WX/ALERT key to
toggle between Weather and Marine
Modes. In Weather Mode the Radio
Status Display will show WX MODE for
three seconds and the WX indicator will
be shown. (Fig. 11a) When switching
back to Marine Mode, the Radio Status
Display will show USA MODE or INT
MODE or CAN MODE for three sec-
onds. (Fig. 11b)
•While in Weather Mode, use the ▲or
▼keys to select from ten weather
channels. Most areas of the US are
covered by Weather Channels 01, 02,
and 03. The Radio Status Display
will verify which channel you’ve
selected (WEATHER1) as you
change channels.
•If you press the 16/9/TRI key while
in weather Mode, the radio will
change from the current weather
channel to Channel 16, then to
Channel 9, and then back to the
weather channel. The WX indicator
will flash, indicating that you are still
in weather Mode, while listening to
Channels 16 and 9.
•While in Weather Mode, the MEM,
UIC, SCAN, H/L keys will not work.
If they are pressed , the radio will
sound an error tone.

Mode
12. Weather Alert
Weather Alert is a safety function that
allows the radio to monitor the local
weather channel for NOAA Weather
Alerts, while allowing you to listen to
other channels.
To set or cancel the Weather Alert func-
tion, press and hold the WX/ALERT key.
The display will switch from the current
channel display (Fig. 12a) to the Weather
Alert display for three seconds. The Radio
Status Display will show WX ALERT
ON. After three seconds, the display will
switch back to the current channel dis-
play. (Fig. 12b)
While in Weather Alert Mode, the radio
will check the last-used weather channel
for alert tones every seven seconds. When
an alert tone is detected, the radio will
cancel the Alert option and change to the
weather channel. It will also sound an
alert detect alarm at maximum volume for
10 seconds.
•If you’re using Weather Mode, and
the Alert option is on, the radio will
mute the speaker even though there is
a signal, until an alert tone is detect-
ed. This allows you to be aware of
alerts, but without having to listen to
the weather continuously. (Fig. 12c)
•When an alert tone is detected, the
Scan and Triple Watch functions are
cancelled.
