RWARNING NEVER connect the transceiver to an
AC outlet. This may pose a fire hazard or result in an electric
shock.
RWARNING HIGH VOLTAGE! NEVER touch
the antenna or an internal antenna connector during trans-
mission. This may result in an electric shock or a burn.
NEVER connect the transceiver to a power source of more
than 16 V DC. This connection will ruin the transceiver.
WHEN INSTALLING THE DSC UNIT NEVER trans-
mit a distress call when your vessel does not need immedi-
ate help. Distress calls can be used only in times of
emergency.
iii
READ ALL INSTRUCTIONS carefully and com-
pletely before using the transceiver.
SAVE THIS INSTRUCTION MANUAL—This in-
struction manual contains important operating instructions for
the IC-M59EURO.
YOU MUST HAVE a DSC vessel ID in order to operate
the optional DSC functions of the transceiver. See your
Dealer for details.
The IC-M59 EURO complies with the essential requirements of
the 89/336/EEC directive for Electromagnetic Compatibility.
IMPORTANT
CAUTIONS
AVOID using or placing the transceiver in direct sunlight or
in areas with temperatures below –20°C or above +60°C.
DO NOT operate the transceiver without running the ves-
sel’s engine. When your vessel’s engine is OFF and the trans-
ceiver is transmitting, the vessel’s battery will soon become
exhausted.
KEEP the transceiver out of the reach of children.
KEEP the antenna cable and DC power cable as far away
as possible from electrical pumps, generators and other elec-
tronic instruments to prevent instrument malfunctions.
KEEP the transceiver and microphone at least 1 meter
away from your vessel’s magnetic navigation compass.

OPERATING RULES 1
1
DPriorities
•Read all rules and regulations pertaining to 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
SHIP STATION LICENSE
When your craft is equipped with a VHF FM transceiver, you
must have a current radio station license before using the
transceiver. It is unlawful to operate a ship station which is not
licensed.
Inquire through your dealer or the appropriate government
agency for a Ship-Radiotelephone license. This license in-
cludes the call sign which is your craft’s identification for radio
purposes.
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.
The Restricted Radiotelephone Operator Permit must be
posted near the transceiver or be kept with the operator. 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 regulations.

■General
When an optional UX-120 DSC UNIT with RC-18 DISTRESS
SWITCH BOX
is installed, digital selective calling (DSC class-F)
is available with via the IC-M59EURO.
DSC is a method of radio communications involving digital
signals rather than the more conventional method of voice
communications. The advantage of using digital communica-
tions over voice communications is that information (espe-
UX-120 required
cially useful for distress calls and other urgent matters) can
be pre-programmed into a radio and transmitted accurately.
In addition, when a GPS receiver (NMEA0183 ver. 1.5, 2.0 or
2.1) is connected, your vessel’s position and the current UTC
time are transmitted together with the vessel’s identity when
making a distress call.
See pgs. 23, 24 for unit installation.
DSC TYPE DESCRIPTION REF.
Distress call This sends distress information which includes your vessel’s ID (and position data/UTC time
when a GPS receiver is connected). Send under emergency conditions only. DSC acknowl-
edgement will be received from a coast station after making a distress call.
pgs.
13, 16
Distress relay call This is used to alert Coast stations (or other ships) when a vessel in distress is unable to do so.
The IC-M59EURO can only receive this type of signal; not transmit. p. 16
All ships call This signal includes a category and channel data which allows a receiving transceiver to au-
tomatically select channel 16 for voice communication. pgs.
14, 16
Individual call This is used for calling to a specific vessel. The IC-M59EURO has no individual call transmis-
sion capability, but has receive capability. Two kinds of acknowledgements (able to comply/un-
able to comply) are available after receiving an individual call.
pgs.
15, 17
Geographical area call This is used for announcement to all ships in the specified area—when a GPS receiver is con-
nected calls directed to areas other than yours are rejected. Receive only for the IC-M59EURO.p. 17

➂When a distress acknowledge-
ment is received, emergency
alarm sounds and channel 16
is automatically selected.
•Push [16•CLR] to stop the alarm.
➃Transmit your distress call particulars by voice using the fol-
lowing procedure:
1. “MAYDAY.”
2. “THIS IS (name of your vessel).”
3. The 9-digit identity AND the call sign (or other vessel
identification).
4. Your vessel’s position if DSC does not include it.
5. The nature of the distress and assistance required.
6. Any other information which might facilitate the rescue.
NOTE: When a GPS receiver (NMEA 0183) is connected,
your vessel’s position is automatically transmitted with the
distress call.
NOTE: Acknowledgement of a DSC distress alert is nor-
mally made by coast stations only.
