3. ABOUT THIS RADIO

3.1 ABOUT THE VHF MARINE BAND

WARNING:

The radio frequencies used in the VHF marine band
lie between 156 and 158 MHz with NOAA Weather
stations available between 161 and 163 MHz. The
marine VHF band provides communications over dis­tances that are essentially “line of sight” Actual transmission range depends
much more on antenna type, gain and height than on the power output of
the transmitter. On a fixed mount 25W radio transmission expected dis­tances can be greater than 15 miles, for a portable 5W radio transmission
the expected distance can be greater than 5 miles in “line of sight”.

The user of a Marine VHF radio is subject to severe fines if the radio is
used on land. The reasoning for this is you may be near an inland water-

way, or propagation anomalies may cause your transmission to be heard in
a waterway. If this occurs, depending upon the marine VHF channel on which
you are transmitting, you could interfere with a search and rescue case, or
contribute to a collision between passing ships. For VHF Marine channel

assignments refer to page 47 section 16.

3.2 ABOUT FRS (FAMILY RADIO SERVICE

)

FRS is a private, two-way, very short-distance voice
communications service for facilitating family and
group activities

Areas of Operation

You may operate your FRS radio in the United States and certain locations
specified by the FCC [95.192].

If you want to use FRS aboard a vessel or aircraft owned or operated by a U.S.
citizen or company, you will need permission from the captain of the vessel.

You must share the channel with other users [95.191(b)]. There is no mean­ingful way to share the channel with others unless you listen before trans­mitting and wait until the channel is available before you transmit. To listen

HX471S Page 9

3.3 ABOUT RECEIVE ONLY CHANNELS and FREQUENCIES

AM/FM Broadcast Bands

The AM/FM bands contained within the HX471S are the same channels you
use every day to listen to music, news and commentary with your car or
home stereo.

The AM broadcast band currently extends from 530
to 1700 kHz. Channels are spaced in even 10 kHz
increments; i.e.: 530, 540, 550, ... , 1600 kHz in the
United States and Canada. Elsewhere, channels are
spaced in 9 kHz increments, i.e.: 531, 540, 549, etc.

The FM broadcast band in the United States extends
from 88 to 108 MHz. Channels are assigned at 200
kHz increments; i.e.: 88.1, 88.3, 88.5, ... , 107.9. The
channels from 88.1 to 91.9 are reserved for non­commercial educational stations. Outside the United States and Canada,
the boundaries and channel spacing vary. In Japan, the band starts at 76
MHz. In Western Europe, the band generally runs from 88-108 MHz, but
channels can be irregularly spaced, i.e.: 101.25 MHz.

AIR (Aircraft) Bands

The AM VHF aeronautical communications band lies
between 108.000 MHz and 136.975 MHz. This fre­quency spectrum can be divided into a lower and
upper range. The lower range between 108.000 MHz
and 118.000 MHz is primarily used for navigational aids such as the ILS ­Instrument Landing Systems, DME - Distance Measuring Equipment, and
VOR’s - Very High Frequency Omni Range. The lower range offers very little
in the way of voice communications, it does however provide someone with
a working knowledge of Morse code the opportunity to identify various bea­cons. The upper range of the aeronautical band 118.000 MHz to 136.975
MHz is where the majority of voice communications can be monitored. Com­munications in the VHF band are transmitted in AM mode and most if not all
compatible receivers automatically default to this mode. Frequencies within
the aeronautical range are spaced in increments of 25 kHz, as such you will
find transmissions at 118.000, 118.025, 118.050 MHz etc.

The frequency(s) you monitor will determine the nature of traffic you will
hear. As previously mentioned frequencies in the lower range of the aero-

HX471SPage 10

nautical band are mostly occupied by navigational equipment and transmit
non voice signals in Morse code. If you select a frequency in the upper
range the air is suddenly filled with conversations between pilots and air
traffic controllers, pilots and their company dispatchers, flight service sta­tions, and ATIS broadcasts. Frequencies within the aeronautical band are
designated according to their usage.

Refer to the page 23 for operation.

4. GETTING STARTED

If the radio has never been used, or its charge is depleted, it may be charged
by connecting the CD-25 Charger Cradle with the NC-72 battery charger, as
shown in the illustration. If 12V DC power is available, the optional E-DC-19
DC Cable with 12 V Cigarette Lighter Plug or the optional E-DC-6 DC Cable
may be used for charging the battery. The NC-72, E-DC-19 and E-DC-6 will
charge a completely discharged FNB-80LI battery pack in about 3 hours.

4.1 BATTERIES AND CHARGERS

The FNB-80LI is a high performance Lithium-Ion battery providing high ca­pacity in a very compact package.

CAUTION

To avoid risk of explosion and injury, FNB-80LI battery pack should only
be removed, charged or recharged in non-hazardous environments.

4.1.1 BATTERY SAFETY

Battery packs for your transceiver contain Lithium-Ion batteries. This type of
battery stores a charge powerful enough to be dangerous if misused or
abused, especially when removed from the transceiver. Please observe the
following precautions:

DO NOT SHORT BATTERY PACK TERMINALS: Shorting the terminals
that power the transceiver can cause sparks, severe overheating, burns,
and battery cell damage. If the short is of sufficient duration, it is possible to
melt battery components. Do not place a loose battery pack on or near metal
surfaces or objects such as paper clips, keys, tools, etc. When the battery
pack is installed on the transceiver, the terminals that transfer current to the
transceiver are not exposed. The terminals that are exposed on the battery
pack when it is mounted on the transceiver are charging terminals only and
do not constitute a hazard.

DO NOT INCINERATE: Do not dispose of any battery in a fire or incinerator.
The heat of fire may cause battery cells to explode and/or release danger­ous gases.

HX471SPage 12

Battery Maintenance

For safe and proper battery use, please observe the following:

r Battery packs should be charged only in non-hazardous environments;
r Use only STANDARD HORIZON-approved batteries;
r Use only a STANDARD HORIZON, (a Marine Division of VERTEX

STANDARD) approved charger. The use of any other charger may
cause permanent damage to the battery.

r Follow charging instructions provided with the chargers.
r Keep the battery contacts clean.

Battery Storage

Store batteries in a cool place to maximize storage life. Since batteries are
subject to self-discharge, avoid high storage temperatures that cause large
self-discharge rates. After extended storage, a full recharge is recommended.

Battery Recycling

DO NOT PLACE USED BATTERIES IN YOUR REGULAR TRASH!
LITHIUM-ION BATTERIES MUST BE COLLECTED, RECYCLED OR DIS­POSED OF IN AN ENVIRONMENTALLY SOUND MANNER.

The incineration, land filling or mixing of nickel-cadmium batteries with the
municipal solid waste stream is PROHIBITED BY LAW in most areas.

Return batteries to an approved lithium-ion battery recycler. This may be
where you purchased the battery.

Contact your local waste management officials for other information regarding
the environmentally sound collection, recycling and disposal of lithium-ion bat­teries.

HX471S Page 13

4.1.2 BATTERY CHARGING

If the radio has never been used, or its charge is depleted, it may be charged
by connecting the CD-25 Charger Cradle with the NC-72 battery charger, as
shown in the illustration. If 12V DC power is available, the optional E-DC-19
DC Cable with 12 V Cigarette Lighter Plug or the optional E-DC-6 DC Cable
may be used for charging the battery. The NC-72, E-DC-19 and E-DC-6 will
charge a completely discharged FNB-80LI battery pack in about 3 hours.

3. Insert the HX471S (with the battery pack) into the CD-25; the antenna
should be at the left side when viewing the charger from the front.

4. If the HX471S is inserted correctly, the Red “CHARGING” indicator will
glow. A fully-discharged pack will be charged completely in approximately
3 hours.

5. The Red “CHARGING” indicator will blink when charging is nearing
completion.

6. When charging is completed, the Red “CHARGING” indicator will disap­pear, and the Green “FULL” indicator will glow. Disconnect the pack from
the CD-25, and unplug the NC-72 from the AC line outlet.

4.1.5 MOUNTING THE CD-25 ON THE VESSEL

The CD-25 is designed to be surface or wall mounted on a vessel which can
be connected to the charger and a GPS that supplies NMEA data for DSC
Distress transmissions.

If mounting on a vessel the CD-25 must be mounted in a location on the
vessel that is directly shielded from rain or splashes of water. After the loca­tion is found mount the CD-25 using the supplied mounting screws.

6.2 RECEPTION

1. Turn the POWER/VOLUME CONTROL knob clockwise to turn the trans­ceiver on.

2. Turn the SQUELCH CONTROL knob fully counterclockwise. This state
is known as “Squelch Off.”

3. Turn up the POWER/VOLUME CONTROL knob until the noise or audio
from the speaker is at a comfortable level.

4. Select the desired operating band among the VHF
Marine band, FRS band, MURS band, FM band,
AM band, and AIR band by pressing the [BAND]
key repetitively to switch between the bands.

5. Turn the squelch control fully to the left so au­dio is heard.

6. Press the [p] or [q] key to select a channel or
frequency that has no signal being received
(no one is transmitting on the channel)

7. Slowly turn the SQUELCH CONTROL knob clockwise and stop immedi­ately after the noise disappears. This condition is known as the “Squelch
Threshold.” If the knob is turned clockwise past this point, weak signals
may not be received. No noise or no signal is heard until a signal is
received that exceeds the squelch threshold. Sometimes, a slight ad­justment of the squelch threshold is needed, as some channels have a
higher noise level than others.

8. Press the [SCAN] key momentarily; the HX471S will begin scanning to­ward a higher channel or frequency and will stop when it receives a
signal strong enough to break through the squelch threshold. Press the
[SCAN] key momentarily to channel the scanning. Refer to section 7.2
for programming channels into scan memory.

9. Please refer to section 16 for VHF Marine and section 3 for FRS and
MURS channel assignments.

6.3 TRANSMISSION

1. Perform steps 1 through 7 of the RECEPTION discussion above.

2. Before transmitting, monitor the channel and make sure it is clear.

THIS IS AN FCC REQUIREMENT!

3. For communications over short distances on the Marine band, press the
[H/L] key until “L” is displayed on the LCD. This indicates Low power
(approximately 1 watt).

Note

Transmitting on 1 watt prolongs battery life. Low power (1 watt)
should be selected whenever possible. On the FRS band, the
transmit power is fixed (0.5 Watt).

4. If using Low power is not effective, select Medium power (2.5 watts) or
High power (5 watts) by pressing the [H/L] key until “M” (Medium power)
or “H” (High power) is displayed.

5. When receiving a signal, wait until the incoming signal stops before trans­mitting. The transceiver cannot transmit and receive simultaneously.

6. Press the PTT (Push-To-Talk) switch to transmit. The “TX” indicator is
displayed during transmission.

7. Speak slowly and clearly into the microphone. Hold the microphone about
1/2 to 1 inch away from your mouth.

8. When the transmission is finished, release the PTT switch.

For an overview of VHF Marine and FRS band operating procedures refer to
section 3.

6.3.1 TRANSMIT TIME - OUT TIMER (TOT)

While the PTT switch is held down, transmission time is limited to 5 minutes.
This prevents prolonged (unintentional) transmissions. About 10 seconds
before automatic transmitter shutdown, a warning beep sounds from the
speaker. The transceiver automatically switches to the receiving mode, even
if the PTT switch is held down. Before transmitting again, the PTT switch
must first be released, and then pressed again. This Time-Out-Timer (TOT)
prevents a continuous transmission that would result from an accidentally
stuck PTT switch.

6.4 NOAA WEATHER CHANNELS

1. To receive a NOAA weather broadcast, press the [WX] key. The trans­ceiver changes to the weather channel mode.
This mode consists of a special preset memory
bank containing the NOAA weather channels.

2. The transceiver will be set to the last used NOAA
weather channel. Press the [p] or [q] key to change to other weather
channels.

3. To exit from the weather channel mode, press the [WX] key. The trans­ceiver will revert to the channel you were using prior to switching to the
weather channel mode.

6.4.1 NOAA WEATHER ALERT

In the event of extreme weather disturbances such as storms and hurri­canes, NOAA (National Oceanic and Atmospheric Administration) sends a
“weather alert” consisting of a 1050 Hz tone, followed by weather reports on
the weather channels. The transceiver is capable of receiving this alert if the
following is performed:

1. Program your area’s weather channels into the transceiver’s scan
memory. Follow the same procedure as for regular channels.

2. Press the [SCAN] key to start the scan.

3. The memorized weather channels are scanned along with the regular
memorized channels. Scanning will not stop on the (continuous) weather
broadcast channels unless the weather alert tone is received.

4. When an alert is received on a weather channel, scanning stops and the
transceiver emits a beeping tone that will stay on for 5 minutes.

5. Press the [WX] key to listen to the Weather Alert.

7.1 USA, CANADIAN, AND INTERNATIONAL CHANNELS

1. To change from US to Canadian or International
Marine Channels, hold down the [16/9] key and
press the [WX] key. The band will change from
USA, to International, and to Canadian with each
press.

2. “USA” appears on the LCD for the USA band,
“CAN” appears for the Canadian band, and
“INTL” appears for the International band.

3. Refer to the marine channel charts in section 16
“VHF MARINE CHANNEL ASSIGNMENTS” for
allocated channels.

7.2 MEMORY SCAN

The HX471S can be programmed to scan channels from a minimum of 2
channels up to all channels in the marine band. If an incoming signal is
detected on one of the channels during scan, the radio will pause on that
channel, allowing you to listen to the incoming transmission.

Select the desired band (VHF Marine, FRS, MURS, AM Broadcast, FM Broad­cast or Air Band) on which you wish to select channels to be scanned.

1. Select the desired channel to be included in the scan memory using the
[p] or [q] key.

2. Press the [MEM] key to store the channel into
the transceiver’s scan memory. “MEM” will be
displayed on the LCD.

3. Repeat steps 1 and 2 for all the channels to be
scanned.

4. To delete a channel from the transceiver’s scan memory, select the memo­rized channel. Press the [MEM] key until “MEM” is removed from the
display.

5. All channels programmed remain in the transceiver’s scan memory even
if the power is turned off. See section 11 “RESETTING THE
TRANSCEIVER’S MICROPROCESSOR” to clear all channels from the
transceiver’s scan memory.

6. Adjust the SQUELCH CONTROL knob until background noise is elimi­nated.

HX471SPage 28

7. To start scanning, press the [SCAN] key. The scan proceeds from the
lowest to the highest programmed channel and stops scanning when a
transmission is received. Scanning will resume when the incoming sig­nal disappears at the end of the transmission. A small “SCAN” icon is
shown on the center bottom of the display during scanning.

8. To stop the scan, press the [SCAN] key.

7.3 PRIORITY SCAN

The priority scanning feature allows the radio to scan while also keeping
watch on a particularly important “priority channel.” The following channels
can be set as the priority channel: 16, 09, and MARINE Preset Channel.

1. To set the priority channel, hold down the [16/9] key and press the [MEM]
key. The channel will change from 16 to 09 to Preset Channels P0 through
P9 with each press of the [MEM] key. When the
[16/9] key is released the displayed channel will
be set as the priority channel (the large “P” icon
will appear at the right side of the channel num­ber).

2. For priority scanning, hold down the [SCAN] key during normal scan­ning. Scanning will proceed between the memorized channels and the
priority channel. The priority channel will be scanned after each pro­grammed channel. A small “PSCN” is shown on the center bottom of the
display during priority scanning.

3. As an example of priority scanning, let us say that marine channels 06,
07, and 08 are memorized in the transceiver’s scan memory. Priority
scanning will proceed in the following sequence:

[

]

CH06

[

[

à

Priority Channel

]

CH08

à

[

Priority Channel

4. Even when the transceiver stops and listens to the signal of a programmed
channel, the transceiver will shift to a “dual watch” mode between this
channel and the priority channel. Therefore, your priority watching of the
designated channel is not compromised when the scanner has paused
on an active channel.

5. Hold down the [SCAN] key to change the priority scanning to normal
scanning, and then press the [SCAN] key to stop the scan and return to
normal operation.

as to keep the hailing channel clear for other users).

7.7 OPERATING ON USA OR CANADIAN 13, OR USA CHANNEL 67

USA and Canadian Channel 13, USA 67 are used at docks, bridges and for
maneuvering in port. Messages on this channel must concern navigation
only, such as meeting and passing in restricted waters. In emergencies and
when approaching blind river bends, high power is allowed. Holding down
the [H/L] key will change the power output from 1 Watt (L) to 5 Watts (H); if
pressed and held again 2.5 Watts (M) will be selected. When the PTT switch
is released, the transceiver will revert to low power. Press and hold in the [H/

L] key again if you need High power on a subsequent transmission.

HX471SPage 30

7.8 OPERATING ON USA CHANNEL 67

USA Channel 67 is used for navigational bridge-to-bridge traffic between
ships. This channel has been allocated for temporary high power transmis­sion if communication is not able to be established on one watt.

Select Channel 67, then press the [H/L] key to set the transmitter output to
either High or Medium power. When the PTT switch is released, the trans-
ceiver will revert to low power.

7.9 DIGITAL SELECTIVE CALLING

7.9.1 GENERAL

7.9.1.1 Digital Selective Calling (DSC)

Digital Selective Calling is a semi-automated method of establishing a radio
call; it has been designated by the International Maritime Organization (IMO)
as an international standard for establishing VHF, MF and HF radio calls. It
had also been designated as part of the Global Maritime Distress and Safety
System (GMDSS). It is planned that DSC will eventually replace aural watches
on distress frequencies and will be used to announce routine and urgent
maritime safety information broadcasts.

The HX471S has a DSC Distress feature that allows mariners to instantly
transmit a VHF Marine distress call with GPS position (when connected to
the transceiver) to the US Coast Guard and other vessels within range of
the transmission.

7.9.1.2 Maritime Mobile Service Identity (MMSI)

What is an MMSI?

An MMSI is a nine digit number used on Marine Transceivers capable of
using Digital Selective Calling (DSC). This number is used by the HX471S
when a Marine DSC Distress call is transmitted. This number is registered
with the USCG. Refer to section 13 “MENU (“SET”) MODE”(MMSI REG).
NOTE: An MMSI must be programmed into the HX471S before the DSC
Distress function will operate. If you have a fixed mounted DSC VHF and
already have a MMSI, this MMSI should be programmed into the HX471S.

How can I obtain a MMSI assignment?

Currently there are two companies that offer MMSI numbers:

¦ Boat US at [phone] or visit the web site http://www.boatus.com/mmsi/.
¦ Seatow at [phone] or visit the web site http://www.seatow.com/

mmsiinfo.htm

HX471S Page 31

WARNING: This radio is designed to generate a digital maritime distress

and safety call to facilitate search and rescue. To be effective as a safety
device, this equipment must be used only within communication range of a
shore-based VHF marine channel 70 distress and safety watch system.

7.9.2 SENDING A DISTRESS CALL

The distress call automatically includes the vessel’s DSC MMSI and Lat/
Lon position. The vessel’s position will only be transmitted if the transceiver
is properly connected to an operating GPS receiver with NMEA output.

1. Lift the red DISTRESS rubber cover on the right side of the transceiver
and press the [DISTRESS] key. “DSC DISTRESS” will appear on the
top of the LCD.

2. Press and hold in the [DISTRESS] key for 3 seconds. The LCD will count
down (3s, 2s, 1s), and afterwards the HX471S will transmit the DSC
Distress Call on channel 70.

3. When the distress signal is being sent, “TX” icon will appear on the LCD.
After the message has been sent, the Distress Alarm will sound.

4. The transceiver “shadow-watches” for a transmission between CH16 and
CH70 until an acknowledgment signal is received.

5. If no acknowledgment is received, the distress call is repeated in three
minute intervals until an acknowledgment is received.

6. To cancel the distress call alarm, press the [16/9] key.

7. To send the CANCEL call:
Press the [DISTRESS] key, then press the [p] or [q] key until “CAN­CEL” is shown on the LCD. Press the [DISTRESS] key.

NOTE: When a GPS receiver with NMEA output is connected via the CD-25
Charger Cradle, the vessel’s position is automatically transmitted with the
distress call. The HX471S will remember the position input from the GPS
until the radio is turned off.

7.10 SIMPLEX/DUPLEX CHANNEL USE

All Marine channels are factory-programmed in accordance with FCC (USA),
Industry Canada and International regulations. The mode of operation can­not be altered from simplex to duplex or vice-versa. Simplex (ship to ship) or
duplex (marine operator) mode is automatically activated, depending on the
channel and whether the USA, International or Canadian operating band is
selected.

HX471SPage 32

8. CTCSS OPERATION ON THE FRS BANDS

8.1 CTCSS CODE OPERATION

CTCSS stands for Continuous Tone Coded Squelch System; it is a sub-

audible tone system with 39 selections, labeled CODE01 through CODE39.
CTCSS tones are used on FRS channels where there are several stations

transmitting on the same frequencies within close proximity to one another.
When this occurs, you may hear multiple communications at the same time
to the point where it is impossible to clearly receive and understand the
transmission of the person calling you.

The HX471S allows you to program CTCSS codes for each FRS channel. If
multiple signals are transmitted on the channel you selected, you will only
hear the transmission of other stations with the same CTCSS tone that was
programmed in the HX471S. If the radio does not receive the correct tone
on the selected channel, then you will not hear the transmission.

1. Select the FRS channel on which you wish to utilize CTCSS control of
the squelch.

2. Press the [MENU] key to enter the Menu Mode.

3. Press the [p] or [q] key to select Menu item (CTCSS).

4. Press the [MENU] key to enable adjustment of this Menu item (“CTCSS”
icon will blink).

HX471SPage 34

10. OPERATING PRACTICES

10.1 EMERGENCY (CHANNEL 16 USE)

Channel 16 is known as the Hail and Distress Channel. An emergency may
be defined as a threat to life or property. In such instances, be sure the
transceiver is on and set to CHANNEL 16. Then use the following proce­dure:

1. Press the microphone push-to-talk switch and say “Mayday, Mayday,
Mayday. This is , , ” (your vessel’s name).

2. Then repeat once: “Mayday, ” (your vessel’s name).

3. Now report your position in latitude/longitude, or by giving a true or mag­netic bearing (state which) to a well-known landmark such as a naviga­tion aid or geographic feature such as an island or harbor entry.

4. Explain the nature of your distress (sinking, collision, aground, fire, heart
attack, life-threatening injury, etc.).

5. State the kind of assistance your desire (pumps, medical aid, etc.).

6. Report the number of persons aboard and condition of any injured.

7. Estimate the present seaworthiness and condition of your vessel.

8. Give your vessel’s description: length, design (power or sail), color and
other distinguishing marks. The total transmission should not exceed 1
minute.

9. End the message by saying “OVER”. Release the microphone button
and listen.

10.If there is no answer, repeat the above procedure. If there is still no
response, try another channel.

10.2 CALLING ANOTHER VESSEL (CHANNEL 16 OR 9)

Channel 16 may be used for initial contact (hailing) with another vessel.
However, its most important use is for emergency messages. This channel

must be monitored at all times except when actually using another channel.
It is monitored by the U.S. and Canadian Coast Guards and by other ves-

sels. Use of channel 16 for hailing must be limited to initial contact
only. Calling should not exceed 30 seconds, but may be repeated 3 times at
2-minute intervals. In areas of heavy radio traffic, congestion on channel 16
resulting from its use as a hailing channel can be reduced significantly in
U.S. waters by using Channel 9 as the initial contact (hailing) channel for
non-emergency communications. Here, also, calling time should not exceed
30 seconds but may be repeated 3 times at 2-minute intervals.

HX471S Page 35

Prior to making contact with another vessel, refer to the channel charts in
this manual, and select an appropriate channel for communications after
initial contact. For example, Channels 68 and 69 of the U.S. VHF Charts are
some of the channels available to non-commercial (recreational) boaters.
Monitor your desired channel in advance to make sure you will not be inter­rupting other traffic, and then go back to either channel 16 or 9 for your initial
contact.

When the hailing channel (16 or 9) is clear, state the name of the other
vessel you wish to call and then “this is” followed by the name of your ves­sel and your Station License (Call Sign). When the other vessel returns your
call, immediately request another channel by saying “go to,” the number of
the other channel, and “over.” Then switch to the new channel. When the
new channel is not busy, call the other vessel.

After a transmission, say “over,” and release the microphone’s push-to-talk
(PTT) switch. When all communication with the other vessel is completed,
end the last transmission by stating your Call Sign and the word “out.” Note
that it is not necessary to state your Call Sign with each transmission, only
at the beginning and end of the contact.

Remember to return to Channel 16 when not using another channel. Some
radios automatically monitor Channel 16 even when set to other channels
or when scanning.

10.3 OPERATING ON CHANNELS 13 AND 67

Channel 13 is used at docks and bridges and by vessels maneuvering in
port. Messages on this channel must concern navigation only, such as meet­ing and passing in restricted waters.

Channel 67 is used for navigational traffic between vessels.
By regulation, power is normally limited to 1 Watt on these channels. Your

radio is programmed to automatically reduce power to this limit on these
channels. However, in certain situations it may be necessary to temporarily
use a higher power. See page 20 ([H/L] key) for means to temporarily over­ride the low-power limit on these two channels.

HX471SPage 36

10.4 PROHIBITED COMMUNICATIONS

The FCC prohibits the following communications:

• False distress or emergency messages:

• Messages to “any boat” except in emergencies and radio tests;

• Messages to or from a vessel on land;

• Transmission while on land;

• Obscene, indecent, or profane language (potential fine of $10,000).

10.5 NOAA WEATHER ALERT TESTING

In the event of a major storm or other appreciable weather condition requir­ing vessels at sea (or other bodies of water) to be notified, the NOAA (Na­tional Oceanographic and Atmospheric Administration) broadcasts a 1050
Hz tone that some VHF radios, including your HX471S, can detect for
“Weather Alarm” purposes (refer to section 6.4.1 “NOAA WEATHER ALERT”
for a discussion of how to use this feature). The 1050 Hz tone, when de­tected, will produce a loud beep in the speaker of the HX471S, to signal that
a Weather Alert Broadcast is being received.

In order to test this system, NOAA broadcasts the 1050 Hz tone every
Wednesday sometime between 11 AM and 1 PM local time. You may use
this opportunity to test your HX471S periodically to confirm that the Weather
Alert feature is working, or for training crew members on how to configure
the HX471S to receive the NOAA Weather Alerts.

HX471S Page 37

11. RESETTING THE TRANSCEIVER’S MICROPROCESSOR

Resetting the microprocessor restores the initial, factory-supplied conditions
in the transceiver. These are called the “default” conditions.

To reset the microprocessor, first turn the transceiver off. Then, while press­ing and holding in the [WX] and [SCAN] keys, turn the transceiver on.

The default conditions are:

• No channel numbers are in scan memory.

• Channel 16 is the priority channel.

• Channel 16 will be selected when the transceiver is turned on.

• WX channel 01 will be recalled when the [WX] key is pressed.

• Preset Channels are unassigned.

Note: The above procedure also resets the microprocessor. Perform this
procedure if an operational problem occurs which cannot be solved by nor­mal operating procedures.

HX471SPage 38

12. CLONING

The HX471S includes a convenient “Clone” feature, which allows the memory
and configuration data from one transceiver to be transferred to another
HX471S.

Turn both radios off.

1. Connect the (optional) CT-32 Clone Cable between the MIC/SP jacks of
the two transceivers.

2. Hold down the [PRESET] key and then turn on the transceiver. Do this
for both transceivers (the order of switching the radios on does not mat­ter); “CLONE” will appear on the display on both transceivers.

3. On the Destination transceiver, press the [MEM] key (“CLONE RX” will
appear on the LCD).

4. Press the [16/9] key on the Source transceiver; “CLONE TX” will appear
on the Source radio, and the data will now be transferred.

5. If there is a problem during the cloning process, “CLONE ERR” is dis­played. Check your cable connections and battery voltage, and try again.

6. If the data transfer is successful, the Destination transceiver will return
to normal operation; Turn both transceivers off and disconnect the Clone
cable. You can then turn the transceivers back on, and begin normal
operation.

15. INSTALLATIONS OF OPTION

â

â

15.1 SU-1 BAROMETRIC PRESSURE UNIT OR
FVP-31 VOICE SCRAMBLER UNIT

1. Make sure that the transceiver is off. Remove the hard or soft case, if

used. Remove the battery pack.

2. Locate the connector for the optional unit under the caution seal in the

battery compartment on the back of the radio; just peel off the caution seal.

3. When installing the Barometric Pressure Unit SU-1, connect the jumper

pads labeled “BARO” (2 pair) by soldering them together. When install­ing the Voice Scrambler Unit FVP-31, connect the jumper pads labeled
“SCRMBL” (8 pair) using the soldering jumper.
Note: It is not possible to install both optional units into the same radio.

4. Align the connector on the optional unit with the transceiver’s connector

and gently press the unit into place.

5. Affix the new caution seal (supplied with the optional unit), and replace

the battery. Installation is now complete.

â

15.2 FBA-23 BATTERY CASE

FBA-23 is a battery case that holds two alkaline batteries and is used with

the HX471S transceiver. Alkaline batteries can be used for transmission in
an emergency, but power output is reduced to one watt, and battery life will
be short.

1. Slide the batteries into the FBA-23 with the Negative [–] side of the batter-

ies touching the spring connections inside the FBA-23.

2. Insert the FBA-23 into the battery compartment on the

back of the transceiver, then close the Battery Pack
Latch until it locks in place with a “click.”

Note: The battery indicator on the transceiver is only ap­plicable to the FNB-80LI rechargeable battery. Disregard
this indication when using alkaline batteries.

HX471SPage 46

16. VHF MARINE CHANNEL ASSIGNMENTS

Tables on the following pages list the VHF Marine Channel assignments for
U.S.A. and International use. Below are listed some data about the charts.

1. VTS. Where indicated, these channels are part of the U.S. Coast Guard’s

Vessel Traffic System.

2. Alpha channel numbers, that is, channel numbers followed by the letter

A (such as Channel 07A) are simplex channels on the U.S.A. or Cana­dian channel assignments whose counterparts in the International as­signments are duplex channels. International channels do not use “al­pha” numbers. If you call the Coast Guard on Channel 16, they will some­times ask you to “go to channel 22 Alpha.” This is a channel assigned
to U.S.A, and Canadian Coast Guards for handling distress and other
calls. If your radio is set for International operation you will go to Chan­nel 22 instead of 22A, and will not be able to communicate with the
Coast Guard. To use Channel 22A, your radio must be set for USA or
Canada operation, using the USA/CAN/INTL channel selection proce­dure described on page 28 of this manual. Channel 22 (without an “A”) is
an International duplex channel for port operations. The HX471S dis­plays an “A” adjacent to the channel number on all “Alpha” channels,
unlike some other models that may not indicate the “A” even though they
may be set to the correct frequency.

3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge

operators on inter-coastal waterways and rivers. It is also used by ma­rine vessels in the vicinity of these bridges for navigation and for com­municating with the bridge operators. Note that a limit of 1 Watt is speci­fied for these channels.

4. The S/D column on the chart indicates either S (simplex) or D (duplex).

Simplex means transmitting and receiving on the same frequency. Only
one party at a time can talk, unlike a telephone. Be sure to say “over”
and release your microphone push-to-talk switch at the end of each trans­mission. Duplex operation involves the use of one frequency for trans­mitting and a separate frequency for receiving. On channels specified
as duplex on the charts, correct mode of operation is established auto­matically by your radio when you select a channel; you cannot change
the mode. And you still must release the push-to-talk switch after each
transmission in order to listen to the radio.

5. Channels normally used by recreational boaters are those that include

HX471S Page 47

the term “non-commercial” in the Channel Use column of the chart. Some
of these are shared with other users and some are used only in certain
geographic regions.

6. Marine vessels equipped with VHF radios are required to monitor

Channel 16.
