INSTRUCTION MANUAL
VHF MARINE TRANSCEIVER
iM402
This device complies with Part 15 of the FCC rules. Operation is subject to the following two conditions: (1) This device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
NOTE FOR RF SAFETY
C AU TIO N
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 6 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 6 meters of the antenna, nor operated at all if any
person is touching the antenna. If the antenna cannot be
installed at 6 meters or graterI, we recommend touse the
one watt setting to minimize RF exposure.
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.
IMPORTANT
READ ALL INSTRUCTIONS carefully and completely
before using the transceiver.
SAVE THIS INSTRUCTION MANUAL — This instruction manual contains important operating instructions
for the IC-M402.
IN CASE OF EMERGENCY
If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a distress call on Channel 16.
Or, transmit your distress call using digital selective calling on
Channel 70.
USING CHANNEL 16
USING DIGITAL SELECTIVE CALLING (Ch 70)
DISTRESS CALL PROCEDURE
DISTRESS CALL PROCEDURE
1. While lifting up the switch cover, push and
hold [DISTRESS] for 5 sec. until you hear 5

station.
1. “MAYDAY MAYDAY MAYDAY.”
2. “THIS IS ...............” (name of vessel)
3. Your call sign or other indication of the vessel
(AND 9-digit DSC ID if you have one).
4. “LOCATED AT ...............” (your position)
5. The kind of the distress and assistance
required.
6. Any other information which might facilitate
the rescue.
• Channel 16 is automatically selected.
3. Push and hold [PTT], then transmit the
appropriate information as at left.

CAUTIONS
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 alcohol when cleaning, as they may damage the transceiver
surfaces.
CAUTION: Changes or modifications to this device, not ex-

hot when operating continuously for long periods.
pressly approved by Icom Inc., could void your authority to
operate this device under FCC regulations.
NEVER connect the transceiver to a power source of more
than 16 V DC or use 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
Place the transceiver in a secure place to avoid inadvertent
use by children.
BE CAREFUL! The transceiver and optional HM-127 employ waterproof construction, which corresponds to JIS waterproof specification, grade 7 (1 m/30 min.). However, once
the transceiver or microphone has been dropped, waterproofing cannot be guaranteed due to the fact that the case
may be cracked, or the waterproof seal damaged, etc.
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.
DO NOT use or place the transceiver in areas with temperatures below –4°F (–20°C) or above +140°F (+60°C) or, in
areas subject to direct sunlight, such as the dashboard.

OPERATING RULES
◊ 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.
(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.
◊ 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.
Radio license for boaters (U.S.A. only)
The Telecommunications Act of 1996 permits recreational
boaters to have and use a VHF marine radio, EPIRB, and
marine radar without having an FCC ship station license.
Boaters travelling on international voyages, having an HF
single sideband radiotelephone or marine satellite terminal,
or required to carry a marine radio under any other regulation must still carry an FCC ship station license. For further
information, see the FCC Ship Radio Stations Fact Sheet.

SCAN OPERATIONS
■ Scan types
Scanning is an efficient way to locate signals quickly over a
wide frequency range. The transceiver has priority scan and

CONNECTIONS AND MAINTENANCE
■ Mounting the transceiver
◊ Using the supplied mounting bracket
EXAMPLE
The universal mounting bracket supplied with your transceiver
allows overhead or dashboard mounting.
• Mount the transceiver securely with the 2 supplied screws
(M5 × 20) to a surface which is more than 10 mm thick and
can support more than 5 kg.
• Mount the transceiver so that the face of the transceiver is at
90° to your line of sight when operating it.
CAUTION: KEEP the transceiver and microphone at
least 1 meter away from your vessel’s magnetic navigation
compass.
NOTE: Check the installation angle; the function display
may not be easy-to-read at some angles.
