xx To change the transmit power, press and hold the ENT-1W/25W for two seconds. The
transmit power switches between 1 watt and 25 watts each time you press and hold
ENT-1W/25W.
Normal mode with Weather Alert Watch
If you activate Weather Alert Watch while operating in normal mode, the radio checks
the most recently-used weather channel every seven seconds. If it detects a weather
alert for your area, it will change the channel to the last-used weather channel. The
radio will not check the weather channel while you are actively transmitting; it waits
until your transmission is finished and then checks the weather channel.
To turn Weather Alert Watch on or off, press and hold CALL-MENU while the radio is
idle. Select Setup and then WX-Alert Mode. Use CHANNEL UP and CHANNEL DOWN to
choose WX Alert Mode setting ON or OFF.
Normal mode with Triple or Dual Watch
If you activate Triple Watch while operating in normal mode, the radio checks channels
16 and 9 every two seconds; with Dual Watch turned on, the radio only checks channel 16.
The radio will not check channels 16 or 9 while you are actively transmitting; it waits until
your transmission is finished and then checks the channels.
Press and hold 16/9-TRI (on the radio or the microphone) for two seconds to turn Triple/
Dual Watch on or off. (To change between Triple or Dual Watch, see page 13.)
Normal mode with both Weather Alert and Triple or Dual Watch
You can activate Weather Alert Watch and Triple or Dual Watch at the same time. The
radio performs both checks at their scheduled time. (To change between Triple or Dual
Watch, see page 13.)
SCAN MODE
You can save channels into memory and then use scan mode to monitor those channels.
When the radio detects a signal on a channel, it pauses on that channel as long as the signal
is received; when the transmission stops, the radio will continue scanning.
In scan mode, you can get the following information from the display (some indicators will
not always be displayed).
Using the radio in scan mode
xx You cannot transmit while in scan mode.
xx You must have two or more channels in memory to start a scan.
xx To save a channel into memory, select the channel, then press and hold WX-MEM for
two seconds. Memory will show on the display.
xx To remove a channel from memory, set the radio to that channel, then press and hold
WX-MEM for two seconds. Memory will no longer show on the display.
xx To activate scan mode, press and hold CLR-SCAN. Press and hold CLR-SCAN again to
return to the previous mode.
xx When the radio automatically stops on a channel, press CHANNEL UP to leave that
channel and resume scanning.
xx To end the scan, press the microphone’s PUSH TO TALK, CALL-MEM, or WX-MEM
buttons. The radio remains on the last scanned channel.
Scan mode with Weather Alert Watch
If you activate Weather Alert Watch while operating in scan mode, the radio checks the
most recently-used weather channel every seven seconds, then continues scanning the
next channel in memory.
To turn Weather Alert Watch on or off, press and hold CALL-MENU while the radio is idle.
Select Setup and then WX-Alert Mode. Use CHANNEL UP and CHANNEL DOWN to choose WX
Alert Mode setting ON or OFF.
Scan mode with Triple or Dual Watch
If you activate Triple Watch while operating in scan mode, the radio checks channels 16
and 9 every two seconds, then goes on to scan the next channel; with Dual Watch turned
on, the radio only checks channel 16.
Press and hold 16/9-TRI (on the radio or the microphone) for two seconds to turn Triple or
Dual Watch on or off. (To change between Triple or Dual Watch, see page 13.)
Press and hold the CLR-SCAN key to turn off Scan mode and set the radio to Triple/Dual
Watch mode.
Scan mode with both Weather Alert and Triple or Dual Watch
You can activate Weather Alert Watch and Triple or Dual Watch at the same time. The
radio performs both checks at their scheduled time. (To change between Triple or Dual
Watch, see page 13.)
WEATHER MODE
In cooperation with the FCC, NOAA also uses the weather channels to alert you of other
hazards besides weather (child abduction alerts, nuclear, biological, etc.). In weather mode,
the radio monitors one of the ten NOAA weather channels. If any type of alert is received
for your area, the radio sounds an alert tone and displays the type of alert. In weather
mode, the display shows the following:
Using the radio in weather mode
xx You cannot transmit while in weather mode.
xx To enter weather mode, press WX-MEM.
xx Weather mode can filter out alerts that do not affect your location if the location code
(FIPS code) of the alert is entered in your radio (see page 13). If you have no FIPS
codes programmed into your radio, the radio will notify you of all alerts in any area.
xx To turn off the radio’s alert tone, press any button.
xx To cancel weather mode and return to the previous marine channel, press the WX-MEM
button again.
Weather mode with Weather Alert Watch
Because weather mode already monitors the weather channels, you don’t need Weather
Alert Watch to check the weather channel every seven seconds. If you activate Weather Alert
Watch while operating in weather mode, it operates as a type of “sleep mode:” the radio stays
on the weather channel and mutes the speaker. If an alert is detected for your area, the radio
sounds an alert tone and turns the speaker back on. This mode is very useful when you are
anchoring for the night but want to stay informed of any hazards in your area.
To turn Weather Alert Watch on or off, press and hold CALL-MENU while the radio is idle.
Select Setup and then WX-Alert Mode. Use CHANNEL UP and CHANNEL DOWN to choose WX
Alert Mode setting ON or OFF.
Weather mode with Triple or Dual Watch
If you activate Triple Watch while operating in weather mode, the radio checks channels 16
and 9 every two seconds; with Dual Watch turned on, the radio only checks channel 16.
Press and hold 16/9-TRI (on the radio or the microphone) for two seconds to turn Triple/
Dual Watch on or off. (To change between Triple or Dual Watch, see page 13.)

(see inside front cover)
Setting the Volume
Turn the volume knob clockwise to increase the speaker volume; turn it counter-clockwise
to decrease the volume.
Setting the Squelch Level
The squelch feature reduces the level of static on the speaker by filtering out the
background channel noise. At the lowest squelch level, the speaker plays all radio signals,
including any noise on the channel. Setting the squelch level higher filters out channel
noise and lets only actual radio transmissions through.
11
While listening to a channel, adjust the SQUELCH knob until the noise is filtered out and
you can only hear the transmission. If you switch to a channel with a lot of noise or with a
weak transmission, you may need to adjust the squelch level again.
## NOTE: Setting the squelch level too high may prevent you from hearing weaker
transmissions. If you are having difficulty hearing a transmission, try setting the squelch

Changing the Channel
Press CHANNEL UP and CHANNEL DOWN briefly to scroll through the channels one channel
at a time. Press and hold CHANNEL UP or CHANNEL DOWN to quickly scroll through the
channels.
Making a Transmission
To make a transmission, press and hold the microphone PUSH TO TALK button. Release the
PUSH TO TALK button when you’re finished talking to let the other party respond.
xx To prevent stuck microphone problems or situations where PUSH TO TALK is pushed
accidentally, the radio limits your talk time to 5 minutes in a single transmission. If you
talk for over 5 minutes continuously, the display shows RELEASE MIC BUTTON.
xx For the best sound quality, hold the microphone about two inches away from your
mouth.
xx You cannot transmit while the radio is in weather mode or scan mode.
xx See the channel lists beginning on page 37 for a list of receive-only channels.
Boosting the Transmission Power
In most situations, the 1 Watt transmission power is all you need. If you find yourself far
away from other stations and have trouble getting a response, you may need to boost the
transmission power from 1 Watt to 25 Watts:
1. Select the channel you want to transmit on.
2. Push and hold ENT-1W/25W for two seconds. The display shows 25 Watts in the upper
left hand corner.
3. The transmit power remains at 25 Watts until you change the setting back. Push and
hold ENT-1W/25W for two seconds. The display shows 1 Watt.
## NOTE: Don’t forget to change the transmission setting back to 1 Watt when you move
closer to other stations.
## NOTE: By default, when you change to channel 16, the radio automatically boosts the
power to 25 Watts. Be sure to change the power back to 1 Watt if you are not making an
emergency transmission.
12
Some channels (for example, channels 13 and 67) limit the power of transmission to 1
Watt so that there is less interference between boaters attempting to use the channel at
the same time. If you switch to one of these channels, the radio changes back to 1 Watt
automatically. See the channel lists beginning on page 37 for a list of power-restricted
channels.
Choosing Triple Watch or Dual Watch
In Triple Watch mode, the radio briefly checks channels 16 and 9 every two seconds. In
Dual Watch mode, the radio checks channel 16 only. Generally, Triple Watch is used in
areas where channel 9 is used as a hailing frequency while Dual Watch is used in areas
where channel 16 is used for distress and hailing. Your radio comes set to use Triple
Watch; if you want to use Dual Watch instead, you will have to select it in the setup:

Using FIPS Codes for Weather Alerts
The US National Weather Service established 6-digit Federal Information Processing
System (FIPS) codes to issue weather alerts in specific areas. You can choose which areas
you want to hear alerts for by entering these FIPS codes in your radio. This can prevent
you from being bothered by events that are far from where you are boating. The radio only
sounds the alert tone if an incoming FIPS code matches one of the areas you selected.
xx For more information about how the NWS uses FIPS codes, see the NWS website: www.
nws.noaa.gov/nwr/nwsfipschg.htm.
xx To see an index of FIPS codes by state, see the website of the National Institute of
Standards and Technology (NIST): www.itl.nist. gov/fipspubs/co-codes/states.htm.
xx For information on the Canadian implementation of FIPS codes, called Canadian
Location Codes, see the website of the Meteorological Service of Canada (MSC): http://
www.msc.ec.gc.ca/msb/weatheradio/transmitter/index_e.cfm
## NOTE: If you travel outside the areas you have entered into your radio, you may not hear
alerts that affect your new location. Be sure to enter the FIPS codes of all the areas you
plan to travel to during this trip.
Follow the steps below to edit the list of FIPS codes. You can store up to 30 different FIPS
codes in your radio.

USING DIGITAL SELECTIVE CALLING (DSC) FEATURES
WHAT IS DSC?
Digital Selective Calling (DSC) is a standard that allows you to call other stations using
their unique identification code (the Maritime Mobile Service Identity or MMSI number),
just like you would call a phone number. To call another station, just enter that station’s
MMSI number and choose the voice channel you want to talk on. The radio uses channel
70 to transmit your MMSI number to the other station along with the voice channel you
requested. If the other station accepts your call, both radios automatically switch to the
requested voice channel so you can talk to the other station.
DSC provides a system for automated distress calls. At the touch of a button, the radio can
transmit your MMSI number, the nature of your distress, and your current position based
on data from your GPS receiver. The radio repeats the distress call every few minutes until
it receives an acknowledgement.
The DSC standard dedicates a VHF channel—channel 70—to digital transmissions only.
Since digital transmissions require less bandwidth voice transmissions, channel 70 avoids
the problems of busy voice channels.
ADVANCED DSC FEATURES
Your radio supports the following DSC features:

WHAT IS AN MMSI NUMBER?
In order to use DSC features, you must be assigned an MMSI number and program that number into
your radio. There are two kinds of MMSI numbers: individual numbers for use by single boats and
group numbers for use by fleets, boating organizations, event coordinators, etc.
You can get more information on MMSI numbers at these resources:
xx The dealer where you purchased the radio
xx Recreational boaters can obtain an MMSI number from the Boat Owner’s Association
of the U.S. (http://www.boatus.com/mmsi/ or call 800-563-1536) or Sea Tow Services
International (http://seatow. com/boating_safety/mmsi.asp)
xx Commercial boaters need a ship station license to get an MMSI number. For more
information, visit the Federal Communications Commission (FCC) website at http://
wireless.fcc.gov/marine/ fctsht14.html.

Suppose you are coordinating safety for a sailboat race. Before the race starts, you instruct
all the racers to enter your group MMSI number into their radios. During the race:
xx Throughout the race, you use group calling to update the racers on the time, race
status, and any course corrections.
xx A power boat full of spectators comes a little too close to the race path. You use
individual calling to contact the power boat and advise them to stay clear of the race.
xx You see a rowboat entering the area, but since it doesn’t have a radio, you can’t
communicate with the rowboat. You use all ships calling to alert all the other boats in

GPS Verification
If the GPS receiver is correctly connected and it transmits valid data, the display shows GPS
Data OK. Press ENT-1W25W to open the GPS status screen and see detailed GPS data:
If the GPS does not send coordinates within 30 minutes, an audible alert sounds once and the
display shows Input GPS. This message remains until the coordinates are updated.
30
After 4 hours, the audible alert sounds again if no coordinates are received and the GPS is
connected. After 23.5 hours, the radio deleted the current coordinates and displays Input
GPS.
See page 14 to manually set the GPS coordinates.
Configuring the GPS
If the radio is receiving valid GPS data, it will automatically set the clock to your local time
based on the GPS location. You can adjust your local time forward or back one hour if
necessary (for example, if you are close to the border of a time zone); you can also adjust
for Daylight Savings Time.
Follow the steps below to adjust the time:

MAINTENANCE AND TROUBLESHOOTING
Due to its rugged design, your radio requires very little maintenance. However, it is a
precision electronic instrument, so you should follow a few precautions:
xx If the antenna has been damaged, you should not transmit except in the case of an
emergency. A defective antenna may cause damage to your radio.
xx You are responsible for continued FCC technical compliance of your radio.
xx You should arrange for periodic performance checks with your dealer.

ENGINE NOISE SUPPRESSION
Interference from the noise generated by the electrical systems of engines is sometimes a
problem with radios. Your radio has been designed to be essentially impervious to ignition
noise and alternator noise. However, in some installations it may be necessary to take
measures to further reduce the effect of noise interference. Your radio’s DC battery wires,
antenna lead, and accessory cables should be routed away from the engine and engine
compartment, and from power cabling carrying high currents. In severe cases of noise
interference, it may be necessary to install a noise suppression kit. Contact the dealer
where you purchased the radio for more information.

EMERGENCY ALERT SYSTEM (SAME) INFORMATION
Types of events
xx A WARNING is an event that alone poses a significant threat to public safety and/or
property, probability of occurrence and location is high, and the onset time is relatively
short.
xx A WATCH meets the classification of a warning, but either the onset time, probability of
occurrance, or location is uncertain.
xx An EMERGENCY is an event that, by itself, would not kill or injure or do property
damage, but indirectly may cause other things to happen that result in a hazard. For
example, a major power or telephone loss in a large city alone is not a direct hazard,
but disruption to other critical services could create a variety of conditions that could
directly threaten public safety.
xx A STATEMENT is a message containing follow up information to a warning, watch, or
emergency.

NMEA OPERATION
This radio supports NMEA0183 version 3.01.
NMEA Input
If you have difficulty getting your radio to receive data from your GPS receiver, check the
device’s configuration. It should be set to the following parameters:
Baud rate
Data bits
Parity
Stop bits
Data amplitude
Drive capability
4800 bps
None
Over 3.0 V
Over 10 mA
The radio supports RMC, GLL, GNS, GGA and ZDA sentences. When these sentences are
received, the radio displays latitude/longitude, date, time, course, and speed. If any
sentence except an RMC or GLL sentence is received, the radio uses the information based
on the following priority order.
xx Status:RMC > GLL > GNS > GGA
xx Latitude/Longitude:RMC > GLL > GNS > GGA
xx UTC Time: RMC > GLL > GNS > GGA > ZDA
xx Date: RMC > ZDA
xx Speed / Course:RMC
## NOTE 1: If the radio receives only a GLL sentence, the radio does not display the current
speed, course, and date.
## Note 2: If the radio receives both RMC and GLL sentences, the radio uses only the RMC
sentence.
## Note 3: Status data is used to check whether the GPS data is valid or invalid.
NMEA Output
When the radio receives a DSC call (Distress, Position Reply, or Position Send), it outputs a
DSC/DSE sentence from the NMEA output port.
## NOTE: When the radio receives a distress call, it outputs a sentence in the following
format:
xx $CDDSC,12,3081234000,,07,00,0354013946,0657,,,S,E*6D
$CDDSE,1,1,A,3081234000,00,60875646*13

REGULATIONS AND SAFETY WARNINGS
MARITIME RADIO SERVICES OPERATION
WARNING! This transmitter will operate on channels/frequencies that have restricted use
in the United States. The channel assignments include frequencies assigned for exclusive
use of the U.S. Coast Guard, use in Canada, and use in international waters. Operation
on these frequencies without proper authorization is strictly forbidden. See the channel
tables beginning on page 37 for a list of available channels and their uses. If you are still
not certain which channels to use, see the FCC maritime radio page at the FCC website
(http:// wireless.fcc.gov/marine/) or contact the FCC Call Center at 1-888-CALLFCC. For
individuals requiring a license, such as commercial users, you should obtain a license
application from your nearest FCC field office (for US users) or Industry Canada (for
Canadian users).
BASIC RADIO GUIDELINES
You should familiarize yourself with the rules on marine radios and be aware of which
rules apply to your boat. Complete guidelines for all ship and marine radio types can be
found at the US Coast Guard website under the topic Radio Info for Boaters (the direct link
is http://www.navcen.uscg. gov/marcomms/boater.htm). Here are a few guidelines that
affect nearly all s.
xx If you have a VHF radio on your boat, you must maintain a watch on channel 16
(156.800 MHz) whenever the radio is not being used to communicate. Effective from
2004, if a radio is carried, it must be turned on and set to channel 16 whenever your
vessel is underway.
xx If you hear a distress call, wait a few minutes to let a shore station or Coast Guard
vessel respond. If no other station has responded after 5 minutes, you must respond to
the distress call.
xx Do not make false mayday or distress calls as a prank or to test your radio. (This is
essentially like making a false 9-1-1 call; you may be subject to fines.)
