INSTALLATION NOTES
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 that this installation height
should be at least 5 meters above ground (or

accessible) level. 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 5 meters of the antenna, nor
operated at all if any person is touching the
antenna.
In all cases any possible risk depends on the
transmitter being activated for long periods.

(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 transmitter after 1–2 minutes etc.
Similarly some types of transmitter, SSB,
CW, AM, etc. have a lower ‘average’ output
power and the perceived risk is even lower.

IMPORTANT
READ ALL INSTRUCTIONS carefully and completely
before using the transceiver.
CAUTIONS
RWARNING! NEVER connect the transceiver to an AC
outlet. This may pose a fire hazard or result in an electric
shock.
NEVER connect the transceiver to a power source of more
than 16 V DC or using reverse polarity. This will ruin the transceiver.
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.
NEVER place the transceiver where normal operation of the
vehicle may be hindered or where it could cause bodily injury.
KEEP the transceiver at least 3.3 ft (1 m) away from the
ship’s navigation compass.
SAVE THIS INSTRUCTION MANUAL — This in-
struction manual contains important operating instructions for
the IC-M501EURO.
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.
AVOID the use of chemical agents such as benzine or al-
cohol when cleaning, as they may damage the transceiver
surfaces.
BE CAREFUL! The transceiver rear panel will become
hot when operating continuously for long periods.
Place the transceiver in a secure place to avoid inadvertent
use by children.
After exposure to water including fresh water, clean the transceiver thoroughly with fresh water to avoid corrosion.

OPERATING RULES
1
◊ PRIORITIES
•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 signals are prohibited and punishable by law.
◊ PRIVACY
•Information overheard but not intended for you cannot lawfully be used in any way.
• 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.
(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.
The Restricted Radiotelephone Operator Permit must be
posted or 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.
Keep a copy of the current government rules and regulations
handy.
