1.2 SAFETY INFORMATION
Your wireless handheld portable transceiver contains a low power transmit-
ter. When the Push-to-Talk (PTT) button is pushed, the transceiver sends out 
radio frequency (RF) signals. In August 1996, the Federal Communications 
Commission adopted  RF  exposure guidelines  with  safety levels  for  hand-
held wireless devices.
This device is authorized to operate at a duty factor not to exceed 50% (this 
corresponds to 50% transmission time and 50% reception time).
WARNING: To maintain compliance with the FCC’s RF exposure guidelines, 
this  transmitter  and  its  antenna  must  maintain a  separation distance  of at 
least 1 inch (2.5 centimeters) from your face. Speak in a normal voice, with 
the antenna  pointed  up and away  from  the face  at  the  required separation 
distance.
Use only the supplied antenna. Unauthorized antennas, modications, or at-
tachments could damage the transmitter, and may violate FCC regulations.

3. ABOUT THIS RADIO
3.1 ABOUT THE VHF MARINE BAND
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 essen-
tially  “Line  of  sight” Actual  transmission  range  depends  much  more  on  an-
tenna 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 water-
way. If this occurs, depending upon the marine VHF  channel on which  you 
are transmitting, you could interfere with a search and rescue case, or con-
tribute to a collision between passing ships. For VHF Marine channel assign-
ments refer to section “9 VHF MARINE CHANNEL CHART ASSIGNMENT”.
WARNING
This radio is capable of transmitting on Marine VHF. 
The FCC allows the use of VHF Marine band on water areas only. How-
ever  the FCC does not allow the  use of the VHF Marine  band when 
on land. If persons use the VHF  Marine Band on land and interfere 
with others communicating, the FCC will be notied and search for the 
interference. Responsible parties found to be transmitting on the VHF 
Marine Band on land could be ned up to $10,000 for the rst offense.
3.2 ABOUT WATER RESISTANCE
The HX100/HX150 is only submersible※ when the Battery Cover is latched.
※IPX8 Specication for submersibility: 5 ft. (1.5 m) for 30 minutes.
3.3 DISTRESS AND HAILING (CHANNEL 16)
Channel 16 is known as the Hail and Distress Channel. An emergency may 
be dened as a threat to life or property. In such instances, be sure the trans-
ceiver is on and set to “Channel 16”. Then use the following procedure:
1.  Press the PTT (Push-To-Talk) switch  and say  “Mayday,  Mayday, May-
day. 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 mag-

netic bearing (state which) to a well-known landmark such as a naviga-
tion 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.).
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 switch and listen.
10. If there is no answer, repeat the above procedure. If there is still no re-
sponse, try another channel.
3.4 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. Call-
ing should not exceed 30 seconds, but may be repeated 3 times at 2-minute 
intervals. In areas of heavy radio trafc, congestion on channel 16 resulting 
from its use as a hailing channel can be reduced signicantly 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.
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 trafc, 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 ves-
sel 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.

YAESU MUSEN CO., LTD.

HX100/HX150Page 10
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 begin-
ning 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.
3.5 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   key  will  change the  power  output 
from Low Power (1 Watt) to High (5 Watts: HX150, 2.5 Watts: HX100). When 
you change  from  this channel then return to  it, low power will be automati-
cally selected.
3.6 OPERATING ON CHANNEL 67
When  channel  67 is  used  for  navigational  bridge-to-bridge trafc  between 
ships, Normal, High or Medium power may be used temporarily (in the USA 
band) by pressing the    key. When you select this channel again, the 
transceiver will revert to low power.
3.7 SIMPLEX/DUPLEX CHANNEL USE
Refer to the section “9 VHF MARINE CHANNEL CHART ASSIGNMENT” for 
instructions on use of simplex and duplex channels.
NOTE
All channels are factory-programmed in accordance with FCC (USA), 
Industry  Canada  and  International  regulations.  The  mode  of  opera-
tion cannot be altered from simplex to duplex or vice-versa. Simplex 
(ship to ship) or duplex (marine operator) mode is automatically acti-
vated, depending on the channel and whether the USA, International 
or Canadian operating band is selected.

4.2.1 BATTERY SAFETY
Battery  packs  for  your  transceiver contain  Li-ion (for  HX150) or  Ni-MH  (for 
HX100) batteries. This type of battery stores a charge powerful enough to be 
dangerous if  misused  or abused,  especially  when  removed  from the  trans-
ceiver. 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 sufcient duration, it is possible to melt 
battery components. Do not place a loose battery pack on or near metal sur-
faces 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 trans-
ceiver are not exposed.
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 environments;
 Use only STANDARD HORIZON-approved batteries;
 Exceeding the specied temperature limits;
 Reversing  charge  polarity.  Use  only  the  proper  charger.  If  this  is  tam-
pered with or another charger is used, permanent damage may result;
 Use  only a STANDARD HORIZON approved  charger. The  use  of  any 
other charger may cause permanent damage to the battery.
 Follow charging instructions provided with the chargers.
 Submersing the battery in water, or attempting to open the battery casing.
 Keep the battery contacts clean.
Battery Storage
When a battery pack is not used for a long time, please remove it from the 
transceiver. Also, while in storage, the charge will drain slightly over time and 
the battery should be recharged each six months.
Store the 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.

DO  NOT  PLACE  USED  BATTERIES  IN  YOUR 
REGULAR TRASH!
LI-ION AND NI-MH BATTERIES MUST BE 
COLLECTED,  RECYCLED  OR  DISPOSED  OF 
IN AN ENVIRONMENTALLY SOUND MANNER.
The  incineration,  land  lling  or mixing  of Li-ion  batteries  with  the  municipal 
solid waste stream is PROHIBITED BY LAW in most areas.
Return batteries  to  an approved Li-ion battery recycler. This may be where 
you purchased the battery.

9. VHF MARINE CHANNEL ASSIGNMENTS
Tables on  the  following columns  list  the VHF  Marine  Channel assignments 
for USA. 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 Trafc System.
2.  Alpha channel numbers, that is, channel numbers followed by the letter A 
(such as Channel 07A) are simplex channels on the USA. or Canadian 
channel assignments whose counterparts in the International assign-
ments  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 USA, 
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 com-
municating 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 au-
tomatically 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.
