CAUTIONS
IN CASE OF EMERGENCY
RWARNING! NEVER connect the transceiver to an
AC outlet. This may pose a fire hazard or result in an electric
shock.
RWARNING! NEVER hold the transceiver so that the
antenna is very close to, or touching exposed parts of the
body, especially the face or eyes, while transmitting. The
transceiver will perform best if the microphone is 5 to 10 cm
away from the lips and the transceiver is vertical.
NEVER connect the transceiver to a power source other
than the BP-204. Such a 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).
KEEP the transceiver out of the reach of children.
KEEP the transceiver at least 1 meter away from your ves-
sel’s magnetic navigation compass.
If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a distress call on channel 16.

OPERATING RULES
1
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-M3A is capable of operation
on VHF marine channels 3, 21, 23, 61, 64, 81, 82 and 83,
according to FCC regulations these simplex channels cannot be lawfully used by the general public in USA waters.

same brand, type and capacity. Also, do not mix new and
old batteries together.
• Keep battery contacts clean. It’s a good idea to clean
battery terminals once a week.
Ni-Cd • • ALKALINE
■ Battery charging
Prior to using the transceiver for the first time, the Ni-Cd bat-
teries must be fully charged for optimum life and operation.
CAUTION: To avoid damage to the transceiver, turn it
OFF while charging.
• Recommended temperature range for charging:
+50°F to +104°F (+10°C to +40°C)
• Use the supplied AC adapter (BC-131A) only. NEVER use
other adapters.
• An optional cable OPC-254L (for 12 V power source) or CP12L (for 12 V cigarette lighter socket) can be used instead of
the supplied AC adapter.
Before connecting DC power, make sure the internal
switch is set to the proper battery type—Ni-Cd or alkaline.
NEVER connect DC power to the battery case when installing alkaline batteries. Such a connection will damage
the transceiver.

- The charge indicator lights red.
r Charge the Ni-Cd batteries for 15 hours.
CAUTION: Make sure the [CHARGE] switch is in the
ALKALINE position when operating the transceiver with
alkaline batteries.
■ Battery cautions
NEVER incinerate used Ni-Cd batteries. Internal battery gas
may cause an explosion.
NEVER immerse batteries in water. If the battery case becomes wet, be sure to wipe it dry BEFORE attaching it to the
transceiver.
NEVER short terminals of the battery case. Also, current may
flow into nearby metal objects so be careful when placing battery cases in handbags, etc.
If your Ni-Cd batteries seem to have no capacity even after
being charged, completely discharge them by leaving the
power ON overnight. Then, fully charge the Ni-Cd batteries
again. If the Ni-Cd batteries still do not retain a charge (or
very little), new Ni-Cd batteries must be purchased.
