IN CASE OF EMERGENCY
If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a Distress call on Channel 16.
Or, transmit your Distress call using digital selective calling
on Channel 70.
INSTALLATION NOTE
Installation:
The installation of this equipment should be made in such a
manner as to respect the EC recommended electromagnetic
field exposure limits. (1999/519/EC)
The maximum RF power available from this device is 25
watts. The antenna should be installed as high as possible
for maximum efficiency and the installation height should be
at least 1.4 meters above any accessible position. In the case
where an antenna cannot be installed at a reasonable height,
then the transmitter should neither be continuously operated
for long periods if any person is within a distance of 1.4 me-
ters of the antenna, nor operated at all if any person is touch-
ing the antenna.
It is recommended that antenna of a maximum gain of 3 dB
are used. If higher gain antenna are required then please
contact your Icom distributor for revised installation recom-
mendations.
Operation:
The exposure to RF electromagnetic field is only applicable
when this device is transmitting. This exposure is naturally re-
duced due to the nature of alternating periods of receiving and
transmitting. Keep your transmissions to the minimum neces-
sary.
USING CHANNEL 16
DISTRESS CALL PROCEDURE

RADIO OPERATOR WARNING
WARNING
Icom requires the radio operator to meet the
FCC and IC Requirements for Radio Fre-
quency Exposure. An omnidirectional antenna
with gain not greater than 9 dBi must be
mounted a minimum of 5 meters (measured
from the lowest point of the antenna) vertically
above the main deck and all possible personnel. This is the
minimum safe separation distance estimated to meet all RF
exposure compliance requirements. This 5 meter distance is
based on the FCC and IC Safe Maximum Permissible Expo-
sure (MPE) distance of 3 meters added to the height of an
adult (2 meters) and is appropriate for all vessels.
For watercraft without suitable structures, the antenna must
be mounted so as to maintain a minimum of 1 meter verti-
cally between the antenna, (measured from the lowest point
of the antenna), to the heads of all persons AND all persons
must stay outside of the 3 meter MPE radius.
Do not transmit with radio and antenna when persons are
within the MPE radius of the antenna, unless such persons
(such as driver or radio operator) are shielded from antenna
field by a grounded metallic barrier. The MPE Radius is the
minimum distance from the antenna axis that person should
maintain in order to avoid RF exposure higher than the al-
lowable MPE level set by FCC and IC.
FAILURE TO OBSERVE THESE LIMITS MAY ALLOW
THOSE WITHIN THE MPE RADIUS TO EXPERIENCE RF
RADIATION ABSORPTION WHICH EXCEEDS THE MAXI-
MUM PERMISSIBLE EXPOSURE (MPE) LIMIT.
IT IS THE RESPONSIBILITY OF THE RADIO OPERATOR
TO ENSURE THAT THE MAXIMUM PERMISSIBLE EXPO-
SURE LIMITS ARE OBSERVED AT ALL TIMES DURING
RADIO TRANSMISSION. THE RADIO OPERATOR IS TO
ENSURE THAT NO BYSTANDERS COME WITHIN THE
RADIUS OF THE MAXIMUM PERMISSIBLE EXPOSURE
LIMITS.
Determining MPE Radius
THE MAXIMUM PERMISSIBLE EXPOSURE (MPE) RA-
DIUS HAS BEEN ESTIMATED TO BE A RADIUS OF
ABOUT 3 M PER OET BULLETIN 65 OF THE FCC.
THIS ESTIMATE IS MADE ASSUMING THE MAXIMUM
POWER OF THE RADIO AND ANTENNAS WITH A MAXI-
MUM GAIN OF 9 dBi ARE USED FOR A SHIP MOUNTED
SYSTEM.

AVERTISSEMENT POUR LES OPÉRATEURS RADIO
Icom exige que l’opérateur radio se conforme
aux exigences de la FCC et d’IC en matière
d’exposition aux radiofréquences. Une antenne
omnidirectionnelle dont le gain ne dépasse pas 9
dBi doit être fixée à une distance minimale de 5
mètres (mesurée depuis le point le plus bas de
l’antenne) verticalement au-dessus du pont principal et de tout le
personnel qui peut s’y trouver. Il s’agit de la distance de sécurité mini-
male prévue pour satisfaire aux exigences de conformité en matière
d’exposition aux RF. Cette distance de 5 mètres est établie en fonc-
tion de l’exposition maximale admissible sécuritaire de 3 mètres
établie par la FCC et d’IC, à laquelle on ajoute la hauteur d’un adulte
(2 mètres); cette distance convient pour tous les navires.
Dans le cas des embarcations sans structure convenable, l’antenne
doit être fixée de façon à maintenir une distance minimale de 1 mètre
verticalement entre cette antenne (mesurée depuis son point le plus
bas) et la tête de toute personne présente; toutes les personnes
présentes doivent se tenir à l’extérieur d’un rayon d’exposition maxi-
male admissible de 3 mètres.
Ne pas émettre à l’aide de la radio et de l’antenne lorsque des
personnes se trouvent à l’intérieur du rayon d’exposition maximale
admissible de cette antenne, à moins que ces personnes (comme
le conducteur ou l’opérateur radio) ne soient protégées du champ
de l’antenne par un écran métallique relié à la masse. Le rayon
d’exposition maximale admissible équivaut à la distance minimale
que cette personne doit maintenir entre elle et l’axe de l’antenne pour
éviter une exposition aux RF supérieure au niveau d’exposition maxi-
male admissible fixé par la FCC et d’IC.
LE NON-RESPECT DE CES LIMITES PEUT CAUSER, POUR LES
PERSONNES SITUÉES DANS LE RAYON D’EXPOSITION MAXI-
MALE ADMISSIBLE, UNE ABSORPTION DE RAYONNEMENT
DE RF SUPÉRIEURE À L’EXPOSITION MAXIMALE ADMISSIBLE
FIXÉE.
L’OPÉRATEUR RADIO EST RESPONSABLE D’ASSURER QUE
LES LIMITES D’EXPOSITION MAXIMALE ADMISSIBLE SOIENT
RESPECTÉES EN TOUT TEMPS PENDANT LA TRANSMISSION
RADIO. L’OPÉRATEUR RADIO DOIT S’ASSURER QU’AUCUNE
PERSONNE PRÉSENTE NE SE SITUE À L’INTÉRIEUR DU RAY-
ON D’EXPOSITION MAXIMALE ADMISSIBLE.
Établir le rayon d’exposition maximale admissible
ON ESTIME QUE LE RAYON D’EXPOSITION MAXIMALE ADMIS-
SIBLE EST D’ENVIRON 3 M, TEL QUE STIPULÉ DANS LE BUL-
LETIN OET 65 DE LA FCC. CETTE DISTANCE ESTIMÉE TIENT
COMPTE D’UN SYSTÈME INSTALLÉ SUR UN NAVIRE UTIL-
ISANT LA PUISSANCE MAXIMALE DE LA RADIO ET DES AN-
TENNES DONT LE GAIN MAXIMAL EST DE 9 dBi.

DPriorities
• Read all rules and regulations pertaining to call priorities,
and keep an up-to-date copy handy. Safety and distress
calls take priority over all others.
• You must monitor Channel 16 when you are not operating
on another channel.
• False or fraudulent distress calls are prohibited under law.
DPrivacy
• Information overheard, but not intended for you, cannot law-
fully be used in any way.
• Indecent or profane language is prohibited.
DRadio licenses
(1) SHIP STATION LICENSE
You may require a current radio station license before using
the transceiver. It is unlawful to operate a ship station which is
not licensed, but required to be.
If required, contact your dealer or the appropriate govern-
ment agency for a Ship-Radiotelephone license application.
This government-issued license states the call sign which is
your craft’s identification for radio purposes.
(2) OPERATOR’S LICENSE
A Restricted Radiotelephone Operator Permit is the license
most often held by small vessel radio operators when a radio
is not required for safety purposes.
If required, the Restricted Radiotelephone Operator Permit
must be posted or kept with the operator. If required, only a
licensed radio operator may operate a transceiver.
However, non-licensed individuals may talk over a transceiver
if a licensed operator starts, supervises, ends the call and
makes the necessary log entries.
A current copy of the applicable government rules and regu-
lations is only required to be on hand for vessels in which
a radio telephone is compulsory. However, even if you are
not required to have these on hand it is your responsibility to
be thoroughly acquainted with all pertinent rules and regula-
tions.
NOTE: Even though the transceiver is capable of opera-
tion on VHF marine channels 1021, 1023, 1081, 1082 and
1083, according to FCC regulations these simplex chan-
nels cannot be lawfully used by the general population in
USA waters.

the supplied OPC-1540 connection cable. The cable is used
to operate from a longer distance. The cable connector can
also be installed as a built-in plug on a cabinet or wall.
To operate from even longer distances, the optional 6 meter
long OPC-1541 extension cable can be used between the
transceiver and the OPC-1540. Up to two OPC-1541 can be
added.
DInstallation
qInsert the OPC-1540 cable connector into the command
microphone jack, and tighten the nut.
wTo use the cable connector as a wall socket, install it as
described to the right.
eUsing the mounting base as a template, carefully mark the
holes where the cable and three screws will be fastened.
rDrill holes at these marks.
tInstall the mounting base using the supplied screws, as
shown below.
