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 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 ?? section 11.

optional E-DC-6 DC Cable may be used for charging the battery. The NC-88, E-DC-19A and
E-DC-6 will charge a completely discharged FNB-V99LI battery pack in about 8 hours.
4.1 BATTERIES AND CHARGERS
The FNB-V99LI is a high performance LI-ion battery providing high capacity in a compact package.
CAUTION
To avoid risk of explosion and injury, FNB-V99LI battery pack should only be removed, charged or
recharged in non-hazardous environments.
4.1.1 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
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.
Battery Maintenance
For safe and proper battery use, please observe the following:
Battery packs should be charged only in non-hazardous environments;
Use only STANDARD HORIZON-approved batteries;
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.

will change from “16” to “09” to Preset Channels “0” through “9” 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 “P” icon will appear at the left side of the channel number).
2. For Priority Scanning, press the [SCAN(DW)] key to activates the Memory Scanning, then
hold down the [SCAN(DW)] key while activating the Memory Scan. Scanning will proceed
between the memorized channels and the Priority Channel. The Priority Channel will be
scanned after each programmed channel.
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] Æ [Priority Channel] Æ [CH07] Æ [Priority Channel] Æ
[CH08] Æ [Priority Channel] Æ [CH06] Æ [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(DW)] key to change the Priority Scan to Memory Scan, and then press
the [SCAN(DW)] key to stop the scan and return to normal operation.

6.13 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.
6.14 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 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.
FCC ID:K6630323X30
IC ID:511B-30323X30
Operating Manual
Vertex Standard Co.,Ltd.
18
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.
6.15 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 ?? ([H/L] key) for means to temporarily
override the low-power limit on these two channels.
6.15 OPERATING ON CHANNEL 13
Channel 13 is 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. Pressing the [H/L(KEY)] key will change the
power output from Low Power (1 Watt) to Medium (2.5 Watts), High (5 Watts), or Normal (6 Watts)
power will be selected. When you select to this channel again, the transceiver will revert to Low
power.
6.16 OPERATING ON CHANNEL 67
When channel 67 is used for navigational bridge-to-bridge traffic between ships, Normal, High or
FCC ID:K6630323X30

19
Medium power may be used temporarily (in the USA band) by pressing the [H/L(KEY)] key. When
you select to this channel again, the transceiver will revert to low power.
6.17 ENABLING S.O.S STROBE OPERATION
The S.O.S. STROBE feature utilizes the high-intensity strobe LED on the front of the HX750S as a
visual distress beacon. When enabled, the LED blinks the internationally-recognized Morse Code
“S.O.S.” message (...---...) at a rate of 5 words per minute. This can be very useful in summoning
help from rescuers who may not be able to communicate with you via radio.
1. Hold down the [MEM] key while turning the radio on to activate the emergency S.O.S. Strobe.
Once the radio comes on, the BUSY/TX LED will flash the Morse Code S.O.S. message
repeatedly.
2. The S.O.S. strobe function is interrupted when a signal is received or if the squelch control is
turned so audio is heard from the speaker and during transmission.
3. To disable the S.O.S. strobe function, turn the radio off and back on again.
7. MENU (“SET”) MODE
The HX750S’s Menu Mode allows a number of the HX750S operating parameters to be
custom-configured for your operating requirements.
The Menu Mode is easy to activate and set, using the following procedure:
1. Turn the transceiver off.
2. Hold down the [SQL] key, and then turn on the transceiver while still holding down the [SQL]
key.
3. The “SEt” will appear on the display, indicating that the Menu (“Set”) Mode has been
activated.
4. Press the [SQL] key to select the Menu item to be adjusted.
5. Press the [T] or [S] key to enable adjustment of the selected Menu item. The menu item will
blink

8. MAINTENANCE
8.1 GENERAL
The inherent quality of the solid-state components in STANDARD HORIZON radios will provide
many years of continuous use. Take the following precautions to prevent damage to the radio.
To prevent corrosion of electrical contacts and keep the water resistance, keep the microphone
connected or the jack covered at all times.
Never key the transmitter unless an antenna or suitable dummy load is connected to the antenna
receptacle.
Ensure that the input voltage does not exceed the value specified in your Owner’s Manual.
Use only STANDARD HORIZON-approved accessories and replacement parts.

9. INSTALLATIONS OF OPTION
9.1 FBA-38 BATTERY CASE
FBA-38 is a battery case that holds five LR03 alkaline batteries and is used with the HX750S
transceiver.
1. Slide the five LR03 alkaline batteries into the FBA-38 with the Negative (–) side of the batteries
touching the spring connections inside the FBA-38.
2. Insert the FBA-38 into the battery nest on the bottom of the transceiver, and then turn the
Battery Pack Lock to the “LOCK” position by a coin.
10. 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 ?? of this manual. Channel 22 (without an “A” is
an International duplex channel for port operations. The HX750S displays an “A” adjacent to
FCC ID:K6630323X30

Operating Manual
Vertex Standard Co.,Ltd.
24
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 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.
