EXPLICIT DEFINITIONS

The explicit definitions described below apply to this
instruction manual.

WORD DEFINITION

RWARNING

CAUTION

NOTE

Personal injury, fire hazard or electric
shock may occur.

Equipment damage may occur.

If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.

PRECAUTIONS

The crossed-out wheeled-bin symbol on
your product, literature, or packaging re­minds you that in the European Union, all
electrical and electronic products, batter­ies, and accumulators (rechargeable bat-

teries) must be taken to designated
collection locations at the end of their working life. Do
not dispose of these products as unsorted municipal
waste. Dispose of them according to the laws in your
area.

Icom, Icom Inc. and the Icom logo are registered trademarks of
Icom Incorporated (Japan) in Japan, the United States, the United
Kingdom, Germany, France, Spain, Russia, Australia, New Zealand,
and/or other countries.

RWARNING! NEVER connect the transceiver di-

rectly to an AC outlet. This may pose a fire hazard or
result in an electric shock.

RWARNING! NEVER mount the transceiver over-

head. The weight of the transceiver is approximately

7.9 kg. (17.4 lb), but its apparent weight will increase
several fold due to wave shocks and vibration. The
transceiver must be mounted on a flat hard surface
only.

NEVER connect a power source of more than 16 V
DC, such as a 24 volt battery. This connection will ruin
the transceiver.

NEVER allow children to play with equipment contain­ing a radio transmitter.

NEVER expose the transceiver to rain, snow or any
liquids.

NEVER install the IC-M700PRO into a positive­grounding ship. Such a connection might blow fuses,
and is not usable.

DO NOT use chemical agents such as benzene or al­cohol when cleaning, as they can damage the trans­ceiver’s surfaces.

i

In maritime mobile operation, KEEP the transceiver
and microphone as far away as possible (at least 1 m)
from the magnetic navigation compass to prevent er­roneous indications.

USE an Icom microphone and/or handset only (sup­plied or optional). Other brands may have different pin
assignments and may damage the transceiver.

DO NOT use or place the transceiver in areas with
temperatures below –20°C (–4°F) or above +60°C
(+140°F).

DO NOT connect the transceiver to a power source
using reverse polarity. This connection will not only
blow fuses but may also damage the transceiver.

DO NOT place the transceiver in excessively dusty en­vironments, or in direct sunlight.

DO NOT place the transceiver against walls, or putting
anything on top of the transceiver. This will obstruct
heat dissipation.

Icom is not responsible for the destruction, damage to, or
performance of any Icom or non-Icom equipment, if the
malfunction is because of:

• Force majeure, including, but not limited to, fires,
earthquakes, storms, floods, lightning, other natural
disasters, disturbances, riots, war, or radioactive
contamination.

• The use of Icom transceivers with any equipment that is
not manufactured or approved by Icom.

OPERATING RULES AND GUIDELINES

❑ CALL PROCEDURES

Calls must be properly identified and time limits must
be respected.

q Give your call sign each time you call another ves-

sel or coast station. If you have no call sign, identify
your vessel name and the name of the licensee.

w Give your call sign at the end of each transmission

that lasts more than 3 minutes.

e You must break and give your call sign at least once

every 15 minutes. during long ship-to-shore calls.

r Keep your unanswered calls short, less than 30

seconds.

Do not repeat a call for 2 minutes.

t Unnecessary transmissions are not allowed.

❑ PRIORITIES

q Read all rules and regulations pertaining to priori-

ties and keep an up-to-date copy handy. Safety and
distress calls take priority over all others.

w False or fraudulent distress calls are prohibited and

punishable by law.

❑ PRIVACY

q Information overheard but not intended for you can-

not be lawfully used in any way.

w Indecent or profane language is prohibited.

❑ LOGS

q All distress, emergency and safety calls must be re-

corded in complete detail. Log data activity is usu­ally recorded in 24 hour time. Universal Time (UTC)
is frequently used.

w Adjustments, repairs, channel frequency changes

and authorized modifications affecting electrical
operation of the equipment must be kept in the
maintenance log; entries must be signed by the au­thorized licensed technician performing or supervis­ing the work.

❑ 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 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,
and ends the call, and makes the necessary log en­tries.

Keep a copy of the current government rules and reg­ulations handy.

■ Functions for receive

D Squelch function

The squelch function detects signals with voice com­ponents and squelches (mutes) unwanted signals,
such as unmodulated beat signals. This provides
quiet standby.

When you need to receive weak signals, the squelch
should be turned OFF.

D Noise blanker

The noise blanker function reduces pulse type noise,
such as that coming from engine ignitions.

The noise blanker may distort reception of strong
signals. In such cases, the noise blanker should be
turned OFF.

Push [SQL] to toggle the function ON or OFF.

• “SQL” appears when the squelch function is turned ON.

Push [NB] to toggle the function ON or OFF.

• “NB” appears when the noise blanker function is turned
ON.

D AGC OFF function

The receiver gain is automatically adjusted accord­ing to the received signal strength with the AGC (Au­tomatic Gain Control) function, to prevent distortion
from strong signals and to obtain a constant output
level.

When receiving weak signals with adjacent strong
signals or noise, the AGC function may reduce the
sensitivity. In this situation, the AGC function should
be deactivated.

D Clarity control

Voice signals received from other stations may be
difficult to receive. This may sometimes happen if a
station is transmitting slightly off frequency. In such
cases, vary the receive frequency only, using the
[CLARITY] control.

Push [AGC] to toggle the function ON or OFF.

• “ê” appears when the AGC function is deactivated.

Adjust [CLARITY] to improve the audio signal.

Transceiver

Copper pipe Metal object Copper screen

The transceiver and antenna tuner MUST have an
adequate ground connection. Otherwise, the overall
efficiency of the transceiver and antenna tuner instal­lation will be reduced. Electrolysis, electrical shocks
and interference from other equipment could also
occur.

For best results, use the heaviest gauge wire or strap
available and make the connection as short as possi­ble. Ground the transceiver and antenna tuner to one
ground point, otherwise voltage differences between
2 ground points may cause electrolysis.

CAUTION: The IC-M700PRO has a negative

ground. NEVER connect the IC-M700PRO to a
“positive ground system,” otherwise the transceiver
will not function.

Ground system example

CONNECTIONS AND INSTALLATION

Good ground points

• Ship’s ground terminal

• External ground plate

• External copper screen

Acceptable ground points

• Stainless steel tuna tower

• Stainless steel stanchion

• Through mast

• Through hull

• Metal water tank

Undesirable ground points

(these points may cause electrolysis)

• Engine block

• Keel bolt

Unusable ground points

(these connections may cause an explosion or elec­trical shock)

• Gas or electrical pipe

• Fuel tank

■ Power source

The transceiver requires regulated DC power of

13.6 V and at least 30 A. There are 3 ways to sup­ply power:

• A direct connection to a 12 V battery in your ship,
through the supplied DC power cable.

CAUTION: The supplied DC power cable MUST be

used to provide power to the transceiver. AVOID ex­ceeding the 3 m (10 ft) length of the DC power cable.
If it is necessary to make a run of over 3 m (10 ft),
use a #6 or similar gauge wire instead of the sup­plied DC power cable, for a maximum run of 6 m
(20 ft).

the cable connection.

CONNECTIONS AND INSTALLATION

■ Antenna

Most stations operate with a whip or long wire (insu­lated backstay) antenna. However, these antennas
cannot be connected directly to the transceiver, since
their impedance may not be matched with the trans­ceiver antenna connector.

WARNING: NEVER mount the transceiver

overhead. The weight of the transceiver is approxi­mately

7.9 kg. (17.4 lb)

, but its apparent weight will
increase several fold due to wave shocks or vibra­tion. The transceiver must be mounted on a flat,
hard surface.

D Mounting example

D Mounting location

Select a location that provides easy access to the front
panel for navigation safety, has good ventilation and
is not subject to sea spray. The face of the transceiver
should be at 90 degrees 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.

Check the installation angle; the display may not be
easy to read at some angles.
