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 
essentially “Line of sight” Actual transmission range depends much more 
on antenna type, gain and height than on the power output of the transmit-
ter.  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 wa-
terway. 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 as-
signments refer to section “10. VHF MARINE CHANNEL ASSIGNMENTS”.
WARNING
This radio is capable of transmitting on Marine VHF radio frequencies.
The FCC allows the use of VHF Marine band on water areas only. Use of 
the VHF Marine band when on land is not permitted. If persons use the 
VHF Marine Band on land and interfere with other communications, 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 PROTECTION
The HX40 is only submersible※ when the MIC/SP cap is installed in the MIC/SP jack.
※IPX7 Specication for submersibility: 3 ft. (1 m) for 30 minutes.
3.3 DISTRESS AND HAILING (CHANNEL 16)
Channel 16 is designated 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 turned 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.).
ApplicationforFCC/IC

5.  State the kind of assistance you 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.
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 BRIDGE CHANNELS 13 AND 67
Channel 13 is used at docks, 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 trafc 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 14 for means to temporarily override the low-
power limit on these two channels.
3.6 SIMPLEX/DUPLEX CHANNEL USE
Refer to the section “10. VHF MARINE CHANNEL ASSIGNMENTS” for in-
structions on use of simplex and duplex channels.
NOTE
All channels are factory-programmed in accordance with FCC (USA), 
ISED (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, de-
pending on the channel and whether the USA, International or Canadian 
operating band is selected.

10. VHF MARINE CHANNEL ASSIGNMENTS
Tables on the following pages 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.

movement of ships in sectors designated by the St. Lawrence Seaway 
Development Corporation or the U.S. Coast Guard. The use of these fre-
quencies outside VTS and ship movement sector protected areas is per-
mitted provided they cause no interference to VTS and ship movement 
communications in their respective designated sectors.
10. Use of 156.875 MHz is limited to communications with pilots regarding 
the movement and docking of ships. Normal output power must not ex-
ceed 1 watt. 5: 156.375 MHz and 156.650 MHz are available primarily for 
intership navigational communications. These frequencies are available 
between coast and ship on a secondary basis when used on or in the 
vicinity of locks or drawbridges. Normal output power must not exceed 1 
watt. Maximum output power must not exceed 10 watts for coast stations 
or 25 watts for ship stations. 
11. On the Great Lakes, in addition to bridge-to-bridge communications, 
156.650 MHz is available for vessel control purposes in established 
vessel trafc systems. 156.650 MHz is not available for use in the Mis-
sissippi River from South Pass Lighted Whistle Buoy “2” and Southwest 
Pass entrance Mid-channel Lighted Whistle Buoy to mile 242.4 above 
Head of Passes near Baton Rouge. Additionally it is not available for use 
in the Mississippi River-Gulf Outlet, the Mississippi River-Gulf Outlet Ca-
nal, and the Inner Harbor Navigational Canal, except to aid the transition

14. RF EXPOSURE SAFETY STATEMENT
SAFETY INFORMATION
Your wireless handheld portable transceiver contains a low power transmitter. When the 
Push-to-Talk (PTT) button is pushed, the transceiver sends out radio frequency (RF) sig-
nals. 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 trans-
mitter and its antenna must maintain a separation distance of at least 1 inch (2.5 centime-
ters) 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  attachments 
could damage the transmitter, and may violate FCC regulations.
CONSIGNES DE SECURITE
Votre émetteur-récepteur portatif sans lcontient un émetteur à faible puissance. Lorsque 
vous appuyez sur le bouton Push-to-Talk (PTT), l’émetteur-récepteur émet des signaux 
de radiofréquence (RF). En août 1996, la FCC (Commission Fédérale des Communica-
tions) a adopté des directives relatives à l’exposition aux RF avec des niveaux de sécurité 
pour les appareils sans l portatifs. Le fonctionnement de cet appareil est autorisé à un 
facteur d’utilisation ne dépassant pas 50 % (correspondant à 50% de la durée de trans-
mission et 50% de la durée de réception).
AVERTISSEMENT: Pour assurer la conformité avec les directives d’exposition RF de la 
FCC, cet émetteur-récepteur et  son antenne doivent être maintenus à une distance  mi-
nimum d’un pouce (2,5 centimètre) de votre visage. Parlez avec une voix normale, avec 
l’antenne dirigée vers le haut et éloignée du visage, à la distance requise. Si vous utilisez 
un casque pour cette radio, et que vous portez la radio sur vous, utilisez exclusivement 
le clip de ceinture Yaesu pour cet émetteur-récepteur, et assurez-vous que l’antenne se 
trouve  à  une  distance  minimum  d’un  pouce  (2,5  centimètres)  de  votre  corps  pendant 
l’émission. Utilisez exclusivement l’antenne fournie. Les antennes, les modicationsou les 
accessoires non autorisés peuvent endommager l’émetteur-récepteur et enfreindre les 
réglementations FCC.
