3. ABOUT THIS RADIO

3.1 ABOUT THE VHF MARINE BAND

The radio frequencies used in the VHF marine band lie between 156 and 162
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 xed mount 25 W radio transmission expected distances can be great­er than 15 miles, for a portable 5 W 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 nes if the radio is used

on land. The reasoning for this is you may be near an inland waterway, 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 34 section 9.

3.2 ABOUT THE LMR CHANNELS

The HX400 is capable of being programmed with 40 LMR (Land Mobile
Radio) channels by a dealer. The frequency range is 134 to 174MHz which
may be setup for 25 kHz (wide) or 12.5 kHz (narrow) channel stepping with
CTCSS and DCS signaling. Contact your dealer for further details.

3.3 ABOUT WATER RESISTANCE

Water resistance of the transceiver is ensured only when the battery pack is
attached to the transceiver and MIC/SP cap is installed in the MIC/SP jack.

3.4 EMERGENCY (CHANNEL 16 USE

Channel 16 is known as the Hail and Distress Channel. An emergency may
be dened 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 PTT (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, re, heart

attack, life-threatening injury, etc.).

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

Page 6

)

HX400

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 PTT
listen.

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

3.5 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 ves­sels. 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 trafc, congestion on channel 16 resulting
from its use as a hailing channel can be reduced signicantly in U.S. waters

by using Channel 9 as the initial contact (hailing) channel for non-emergency
communications. Also hailing on channel 9, the calling time should not ex­ceed 30 seconds but may be repeated 3 times at 2-minute intervals.

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 oth-

er trafc, 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 PTT (Push-To-Talk: )
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.

3.8 SIMPLEX/DUPLEX CHANNEL USE

Refer to the VHF MARINE CHANNEL CHART (page 35) for instructions on
use of simplex and duplex channels.

NOTE

All channels are factory-programmed in accordance with FCC, 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, Canadian or Interna­tional operating band is selected.

4.3 BATTERIES AND CHARGERS

If the radio has never been used, or its charge is depleted, it may be
charged by connecting the CD-50 Charger Cradle with the PA-45B Battery
Charger, as shown in the illustration. If 12V DC power is available, the sup­plied E-DC-30 DC Cable with 12 V Cigarette Lighter Plug may be used for
charging the battery. The PA-45B and E-DC-30 will charge a completely dis­charged FNB-115LI battery pack in approximately 3 hours.

The FNB-115LI is a high performance Li-Ion battery providing high capacity
in a compact package.

CAUTION

To avoid risk of explosion and injury, FNB-115LI battery pack should
only be removed, charged or recharged in non-hazardous environments.

4.3.1 BATTERY SAFETY

Battery packs for your transceiver contain Li-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 sufcient 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 re or incinerator.
The heat of re may cause battery cells to explode and/or release dangerous

gases.

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

Battery packs should be charged only in non-hazardous environ-



ments;

Use only STANDARD HORIZON-approved batteries;



Use only a STANDARD HORIZON approved charger. The use of any



other charger may cause permanent damage to the battery.

6.5 NOAA WEATHER CHANNELS

In the event of a major storm or other appreciable weather condition requir­ing vessels at sea (or other bodies of water) to be notied, the NOAA (Na­tional Oceanographic and Atmospheric Administration) broadcasts a 1050 Hz
tone which the HX400 can detect and alert you of pending storm warnings.
The 1050 Hz tone, when detected, will produce a loud beep in the speaker of
the HX400, to signal that a Weather Alert Broadcast is being received.

9. 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 Trafc 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,
usually by a U/I/C (USA/International/Canada) control or combination of
controls. Channel 22 (without an “A”) is an International duplex channel
for port operations. Some radios indicate an “A” adjacent to the alpha
channels on the display; on others “alpha” is not indicated but the proper
channel is selected based on the U/I/C setting.

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 speci-

ed 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 speci­ed 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

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.
