INSTALLATION NOTES
The installation of this equipment should be
made in such a manner as to respect the EC
recommended electromagnetic field expo-
sure limits (1999/519/EC).
accessible) level. In the case where an an-
tenna cannot be installed at a reasonable
height, then the transmitter should neither be
continuously operated for long periods if any
person is within 5 meters of the antenna, nor
operated at all if any person is touching the
antenna.
(actual recommendation limits are specified
as an average of 6 minutes) Normally the
transmitter is not active for long periods of
time. Some radio licenses will require that a
timer circuit automatically cuts the transmit-
ter after 1–2 minutes etc.
The maximum RF power available from this
device is 25 watts. The antenna should be
installed as high as possible for maximum ef-
ficiency and that this installation height
should be at least 5 meters above ground (or
Similarly some types of transmitter, SSB,
CW, AM, etc. have a lower ‘average’ output
power and the perceived risk is even lower.
In all cases any possible risk depends on the
transmitter being activated for long periods.

IMPORTANT
READ ALL INSTRUCTIONS carefully and completely
before using the transceiver.
SAVE THIS INSTRUCTION MANUAL — This in-
struction manual contains important operating instructions for
the IC-M501EURO.
CAUTIONS
DO NOT use or place the transceiver in areas with temper-
atures below –4°F (–20°C) or above +140°F (+60°C) or, in
areas subject to direct sunlight, such as the dashboard.
RWARNING! NEVER connect the transceiver to an AC
outlet. This may pose a fire hazard or result in an electric
shock.
AVOID the use of chemical agents such as benzine or al-
cohol when cleaning, as they may damage the transceiver
surfaces.
NEVER connect the transceiver to a power source of more
than 16 V DC or using reverse polarity. This will ruin the trans-
ceiver.
BE CAREFUL! The transceiver rear panel will become
NEVER cut the DC power cable between the DC plug and
fuse holder. If an incorrect connection is made after cutting,
the transceiver may be damaged.
hot when operating continuously for long periods.
Place the transceiver in a secure place to avoid inadvertent
use by children.
NEVER place the transceiver where normal operation of the
vehicle may be hindered or where it could cause bodily injury.
After exposure to water including fresh water, clean the trans-
ceiver thoroughly with fresh water to avoid corrosion.
KEEP the transceiver at least 3.3 ft (1 m) away from the
ship’s navigation compass.

OPERATING RULES
1
(2) OPERATOR’S LICENSE
◊PRIORITIES
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.
•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.
The Restricted Radiotelephone Operator Permit must be
posted or kept with the operator. Only a licensed radio opera-
tor may operate a transceiver.
•False or fraudulent distress signals are prohibited and pun-
ishable by law.
However, non-licensed individuals may talk over a transceiver
if a licensed operator starts, supervises, ends the call and
makes the necessary log entries.
◊PRIVACY
•Information overheard but not intended for you cannot law-
fully be used in any way.
Keep a copy of the current government rules and regulations
handy.
•Indecent or profane language is prohibited.
◊RADIO LICENSES
(1) SHIP STATION LICENSE
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 application. This
government-issued license states the call sign which is your
craft’s identification for radio purposes.
