VHF MARINE TRANSCEIVER

iM401EURO

IN CASE OF EMERGENCY

If your vessel requires assistance, contact other vessels and
the Coast Guard by sending a distress call on Channel 16.

USING CHANNEL 16

Or, transmit your distress call using digital selective calling on
Channel 70 (the optional DS-100 (#02) must be installed).

USING DIGITAL SELECTIVE CALLING (ch 70)

(DS-100 DSC CONTROLLER is required)

DISTRESS CALL PROCEDURE

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 nature of the distress and assistance
required.

6. Any other information which might facilitate
the rescue.

Versions of the IC-M401EURO which display the “CE” symbol on the serial number seal, comply with the es­sential requirements of the European Radio and Telecommunication Terminal Directive 1999/5/EC. ò This warn­ing symbol indicates that this equipment operates in non-harmonised frequency bands and/or may be subject to
licensing conditions in the country of use. Be sure to check that you have the correct version of this radio or the
correct programming of this radio, to comply with national licensing requirement.

DISTRESS CALL PROCEDURE

1. Push and hold [DISTRESS] on the DS-100
for 5 sec. until you hear 5 short beeps
change to one long beep.

2. Wait for an acknowledgment from a coast
station.

• Channel 16 is automatically selected.

3. Push and hold [PTT], then transmit the
appropriate information as at left.

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

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.

CAUTION

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

vessel may be hindered or where it could cause bodily injury.

KEEP the transceiver at least 1 m away from the ship’s nav-

igation compass.

SAVE THIS INSTRUCTION MANUAL — This in-

struction manual contains important operating instructions for
the IC-M401EURO.

DO NOT use or place the transceiver in areas with temper-

atures below –20°C or above +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 salt water, clean the transceiver thoroughly
with fresh water to avoid corrosion.

• Do not pour water on the transceiver under the water tap di­rectly.

iii

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.

BASIC OPERATION

■ Channel selection

Channel 16

Channel 16 is the distress and safety channel. It is used for
establishing initial contact with another station and for emer­gency communications. Channel 16 is monitored during both
dualwatch and tri-watch. While standing by, you must monitor
Channel 16.
➥ Push [16] momentarily to select Channel 16.

•Output power turns to “25W” automatically, whenever Channel
16 is selected. For example, when selecting Channel 16 via the
dial, dualwatch/tri-watch or a scan stops at Channel 16, etc.

➥ Push [CH] to return to the condition before selecting Channel

16, or push [Y]/[Z] to select an operating channel.

Call channel

Each regular channel group has a separate leisure-use call
channel. The call channel is monitored during tri-watch. The
call channels can be programmed (p. 9) and are used to store
your most often used channels in each channel group for
quick recall.
➥ Push [16] for 1 sec. to select the call channel of the se-

lected channel group.

•“CALL” and call channel number appear.

•Each channel group may have an independent call channel after

changing a call channel. (U.K. version only)

➥ Push [CH] to return to the condition before selecting call

channel

, or push [Y]/[Z] to select an operating channel.

SCAN OPERATION

■ Scan types

Scanning is an efficient way to locate signals quickly over a
wide frequency range. The transceiver has priority scan and
normal scan.

PRIORITY SCAN

CH 01

CH 06

CH 05 CH 04

Priority scan searches through all tag channels in se­quence while monitoring Channel 16. When a signal is de­tected on Channel 16, scan pauses until the signal disap­pears; when a signal is detected on a channel other than
Channel 16, scan becomes dualwatch until the signal dis­appears.

CH 16

CH 02

CH 03

Set the tag channels (scanned channel) before scanning.
Clear the tag channels which inconveniently stop scanning,
such as channels used for digital communication.

Choose priority or normal scan in set mode. (p. 15)

NORMAL SCAN

CH 01 CH 02

CH 06

CH 05 CH 04

Normal scan, like priority scan, searches through all tag
channels in sequence. However, unlike priority scan, Chan­nel 16 is not checked unless Channel 16 is set as a tag
channel.

■ Antenna

A key element in the performance of any communication sys­tem is an antenna. Ask your dealer about antennas and the
best places to mount them.

■ Fuse replacement

Two fuses are installed in the supplied DC power cable. If a
fuse blows or the transceiver stops functioning, track down
the source of the problem if possible, and replace the dam­aged fuse with a new, rated one.

■ Cleaning

If the transceiver becomes dusty or dirty, wipe it clean with a
soft, dry cloth.

AVOID the use of solvents such as benzene or al­cohol, as they may damage transceiver surfaces.

The universal mounting bracket supplied with your transceiver
allows overhead or dashboard mounting.

•Mount the transceiver securely with the 2 supplied screws
(5 × 20 mm) 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.
