of personal injury, fire or electric shock.
iii
CAUTIONS
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 transmission. 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.
AVOID using or placing the transceiver in direct sunlight or
in areas with temperatures below –20°C (–4°F) or above
+60°C (+140°F).
DO NOT operate the transceiver without running the ves-
sel’s engine. When your vessel’s engine is OFF and the
transceiver 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 electronic instruments to prevent instrument malfunctions.
KEEP the transceiver and microphone at least 1 meter
away from your vessel’s magnetic navigation compass.
IN CASE OF EMERGENCY
If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a distress call on channel 16.

OPERATING RULES
D 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 calls are prohibited under law.
D Privacy
• Information overheard but not intended for you cannot lawfully be used in any way.
• Indecent or profane language is prohibited.
D Radio 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 includes 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 regulations 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.
NOTE: Even though the IC-M45A is capable of operation
on VHF marine channels 3, 21, 23, 61, 64, 81, 82 and 83,
according to FCC regulations these channels cannot be
lawfully used by the general public in USA waters.
