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.

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)
Fig. 8a:Transmitting at High Transmit Power
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.

Fig. 12c: Weather Alert Display in Weather
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.

13. 16/9 Operation
By pressing the 16/9/TRI key briefly, the
radio will change from Channel 16 to
Channel 9 and back to the start channel.
For example, if the start channel is
Channel 24, pressing the 16/9/TRI will
change the channel from 24 to 16 to 9 and
back to 24. (Fig. 13a–13c)
•If the 16/9/TRI key is pressed in
Weather Mode, Weather Mode is
paused temporally and the radio will
change from Channel 16 to Channel
09 to Weather Mode in turn. While
Channel 16 and 09 are displayed, the
WX icon will blink to indicate that
Weather Mode is temporally paused.
•If the 16/9/TRI key is pressed while
scanning, scanning is paused tem-
porarily and it changes from
Scanning Mode to Channel 16 to
Channel 09 to Scanning Mode in
turn.
•If the 16/9/TRI key is pressed in
Triple Watch, Triple Watch operation
is paused temporarily and it changes
from Triple Watch to Channel 16 to
Channel 09 and back to Triple Watch
in turn.

12 Seafit V20 Radio Owner’s Manual
14. Triple Watch
Triple Watch is a handy feature that lets
you monitor a channel of interest to you,
yet maintain a watch on Channels 9 and
16. Let’s say you need to monitor
Channel 15, the Environmental Channel,
but don’t want to miss important safety or
distress messages on Channel 16. Simply
select Channel 15 with the ▲or ▼keys,
then press and hold the 16/9/TRI key.
The TRI icon will be displayed. Every
two seconds, the radio will quickly moni-
tor Channels 16 and 9 before returning to
your selected channel. The Radio Status
Display will show the three channels
being monitored. (Fig. 14a)
•If there is traffic on Channel 9, the
radio will monitor Channel 9 until
the signal stops while checking
Channel 16 every two seconds.
(Fig. 14a)
•If there is traffic on Channel 16, the
radio will monitor Channel 16 until
the signal stops. (Fig. 14b)
•Pressing the ▲or ▼keys in Triple
Watch will increment or decrement
the monitored channel.
15. Scanning Channels
Scanning allows you to monitor the traffic
or conversations on several channels in
quick succession. This can be helpful if
you’re trying to listing to fishing traffic
on several channels, or need to monitor
Race Committee traffic on Channels 68,
69, and 71.
As the radio detects traffic on any channel
in its scan list, it will pause until three
seconds after the last transmission, then
continue scanning.
Before you can scan channels, you need
to store two or more channels into the
radio’s scan memory.

nels from memory
Use the ▲or ▼keys to select a channel
to enter into scan memory. Pressing the
MEM key will enter the channel into the
scan memory (Fig 15a), and the Radio
Status Display will show MEM SET. If
the channel is currently in the scan mem-
ory, pressing the MEM key will remove it
from the scan memory. (Fig. 15b) and the
Radio Status Display will show MEM
DEL.
•Pressing MEM in WX Mode doesn’t
store the Weather Channel in memory
and will result in the error tone.
•Pressing the MEM key while scan-
ning will result in the error tone.
Memory Scan Mode
Memory Scan Mode scans the memorized
channels in ascending (or descending)
order. To enter Memory Scan Mode, press
the SCAN key briefly. (Fig. 15c) If
Channels 6, 16, 22, 68, and 72 have been
entered into memory, the scan sequence
will go from Channel 6 to 16 to 22 to 68
to 72 to 6 to 16 and so on.
The Radio Status Display will show
MEMORY SCAN followed by the list of
channels in memory (in this case,
Channels 6, 16, 22, 68, and 72).
Pressing the SCAN key briefly stops
Memory Scan Mode, and returns the
radio to the channel which was selected
prior to Memory Scan. The Radio Status
Display will show SCAN STOP.
Priority Scan Mode
Priority Scan Mode scans the memorized
channels in ascending (or descending)
order, but checks for traffic on Channel
16 between each memory channel. This
makes it more likely that you’ll be aware
of important traffic on Channel 16.

19. Time out Transmit
Setting
Nothing is more disruptive to Marine
VHF communications than when some
boater has his or her microphone PTT
key pressed accidentally. The problem is
that there is no way to notify him that the
problem exists since the radio cannot
receive traffic.
The V20 has a Time Out Transmit feature
that allows you to set a maximum period
of PTT key press time before the radio
will revert to Receive Mode. This is set at
the factory at five minutes, but you can
enter any value from one to twenty min-
utes, or turn off the feature entirely.
To change the Time Out Transmit setting,
press and hold the MEM key and turn the
power on. Set the TOT time by pressing
the ▲or ▼keys. (Fig. 20a)
•The TOT Range is 00, 01–20.
•00=TOT off
•01=1 minute
•20=20 minutes
After setting the TOT, press the PTT but-
ton to save and exit to Receive Mode.
•If a transmission exceeds the TOT
time, the radio will stop the transmis-
sion and return to Receive Mode. The
message TRANSMIT TIME
EXCEEDED will show in the Radio
Status Display at the bottom of the
screen. (Fig. 20b)
20. Display Back-Light
If any key is pressed, the display and key-
pad light will turn on and remain on for

21. Battery Options for
the V20
The V20 comes with both the BP200
NiMH (Nickel Metal Hydride) recharge-
Fig. 19b:Transmit Time Exceeded display

18 Seafit V20 Radio Owner’s Manual
able battery back as well as an BT200
alkaline battery tray. For most use, the
BP200 battery pack will provide conven-
ient, long life service, and will operate
your radio for approximately 12 hours on
a charge. The length of service depends
largely on how much time you spend
transmitting, and what transmit power
you use.
Charging the BP200
A feature of the NiMH pack is that you
can recharge at any time. The standard
charger SC200 will completely recharge
the BP200 battery pack in approximately
12 hours. If you need the radio prior to a
full charge, you can remove it from the
charger base at any state of charge. The
BP200 will not be damaged by extended
charge time.The best way to use the bat-
tery pack is to detach the battery pack
after full charge
In SC200, when the radio and BP200 are
placed in the SC200 charger base and
power is present, the LED on the front of
the charger base will be red.
The V20 also includes the DC200
Cigarette Lighter Cord. The DC200 can
power the SC200 charger base from any
cigarette lighter socket. The DC200 plugs
into the charger base in the same socket
as the AC power supply.
Use of the Optional RSC200
Rapid Smart Charger
For faster charging of the BP200 battery
pack, the optional RSC200 Rapid Smart
Charger can be used. It will completely
recharge the BP200 in 90 minutes or less,
depending on state of discharge. The
RSC200 is a “smart charger” and will not
damage the BP200 even if the radio is left
in the charger base for long periods. The
best way to use the battery pack is to
detach the battery pack after full charge.
The RSC200 can only be powered by AC
current.
When the radio and BP200 are placed in
the RSC200 charger base and power is
present, the LED on the front of the
charger base will be red if the power is on
but the radio is being charged, or green if
the radio is fully charged.
BT200 Alkaline Battery Pack
The BT200 alkaline battery pack can be
used as a backup to the BP200 battery
pack when charging may not be possible
or convenient. It holds 6 AA batteries.
When the alkaline batteries have dis-
charged, dispose of them safely. They
cannot be recharged using the supplied
chargers.
Make sure to observe the polarity shown
on the inside of the alkaline battery tray
when installing the batteries.
Alkaline batteries have excellent shelf life
when kept in a cool environment, but they
can leak under certain circumstances. If
you store your radio for extended periods,
we recommend that you remove the alka-
line battery tray from the radio.
22. Maintenance
•The V20 is designed to provide years
of trouble free operation with virtual-
ly no maintenance. Follow these sim-
ple procedures to ensure that the V20
continues to deliver top performance.
•Rinse the V20 thoroughly with fresh
water after exposure to salt water.
Otherwise the radio’s keys, switches,
and controllers may become inopera-
ble due to salt crystallization.
•Be Careful! The V20 employs JIS 7
waterproof construction (submersion
to 1 m. depth for 30 min.). However,
waterproofness cannot be guaranteed
over time. Extreme shock (dropping,
etc.) may crack the case or dislodge
or damage the seals. Additionally,
wear or improper battery pack instal-
lation can damage the battery com-

partment seal.
•Keep your battery contacts clean!
Wipe frequently. If visible corrosion
appears, polish with an emery cloth
or similar fine abrasive.
•Never transmit without an antenna
attached to avoid damage to the radio.
•Avoid using or placing the V20 in
areas with temperatures below -20ºC
(-4ºF) or above +60ºC (+140ºF). Do
not place in windshields, etc.
23.Troubleshooting Guide
Symptom: The radio does not respond to key presses. The channel cannot be
changed.
Probable Cause: Key Lock is on.
Remedy: Press the Ikey (on the left side of the case, below the PTT key) for
three seconds to unlock the key pad.
Symptom: You have arranged to communicate with another VHF radio user on a
specific channel, and you can’t hear them.
Probable Cause: You and the other user are using different Country Codes.
Remedy: Make sure that you are both using the same Country Mode (USA,
International, or Canadian). Several channels have the same numeric
designation, but are either on different frequencies or the channels are
used for different purposes. Channel 16, the Distress, Safety, and
Calling channel, is the same on all three bands.
Symptom: You cannot change the transmit power setting.
Probable Cause: You are on a channel which is limited to 1 watt transmit power (e.g. Ch.
13) or you are on a “receive only” channel (e.g. WX ).
Remedy: Change to an unrestricted TX/RX channel.
Symptom: The SCAN key does not start the scan function.
Probable Cause 1: No channels are in the scan memory.
Remedy 1: Use the MEM key to enter desired channels into the scan memory.
Probable Cause 2: Squelch is not adjusted correctly.
Remedy 2: Adjust the squelch to the point that background noise just disappears.
Symptom: Radio just does not seem to be operating correctly.
Probable Cause: The radio has become “confused” by an unusual pattern of key presses.
Remedy: Turn off the radio. Hold down the 16/9/TRI key while turning the radio
on. This process will reset the radio to the original factory settings.
Symptom: Radio will not power up.
Probable Cause: The battery is exhausted.
Remedy: Recharge the battery pack or use the BT200 alkaline battery tray with
fresh alkaline batteries.
Symptom: You can hear transmissions, but the other radio cannot hear you.
Probable Cause: The transmit power is set to low.
Remedy: Use the H/L key to select a higher transmit power setting.
