IMPORTANT

READ THIS INSTRUCTION MANUAL CAREFULLY

before attempting to operate the transceiver.

SAVE THIS INSTRUCTION MANUAL—This manual
contains important safety and operating instructions for
the IC-M700PRO SSB RADIO TELEPHONE.

EXPLICIT DEFINITIONS

The explicit definitions described below apply to this
instruction manual.

PRECAUTIONS

RWARNING! NEVER connect the transceiver to an

AC outlet directly. 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 8
kg., 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 plus-grounding
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.

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.

AVOID using or placing the transceiver in areas with
temperatures below –20°C (–4°F) or above +60°C
(+140°F).

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

AVOID placing the transceiver in excessively dusty en­vironments or in direct sunlight.

AVOID placing the transceiver against walls or putting
anything on top of the transceiver. This will obstruct
heat dissipation.

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.

OPERATING RULES AND GUIDELINES

❑ CALL PROCEDURES

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

➀ Give your call sign each time you call another vessel

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

➁ Give your call sign at the end of each transmission

that lasts more than 3 min.

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

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

➃ Keep your unanswered calls short, less than 30 sec.

Do not repeat a call for 2 min.

➄ Unnecessary transmissions are not allowed.

❑ PRIORITIES
➀

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.

➁ False or fraudulent distress calls are prohibited and

punishable by law.

❑ PRIVACY
➀

Information overheard but not intended for you can­not be lawfully used in any way.

➁ Indecent or profane language is prohibited.

❑ LOGS
➀

All distress, emergency and safety calls must be
recorded in complete detail. Log data activity is usu­ally recorded in 24 hour time. Universal Time (UTC)
is frequently used.

➁ 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.

■ Ground connection

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.

R CAUTION: The IC-M700PRO has a negative

ground. NEVER connect the IC-M700PRO to a
“plus-grounding ship,” otherwise the transceiver
will not function.

Ground system example

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

• Oil-catch pan

■ Power source

The transceiver requires regulated DC power of 13.6
V and at least 30 A. There are 3 ways to supply
power:

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

• Use the PS-60

DC POWER SUPPLY

to connect to an

AC outlet.

• Use the PS-66 DC-

DC CONVERTER

to connect to a

19–32 V DC power source.

R 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, use #6 or similar weight cable instead of
the supplied DC power cable for a maximum run
of 6 m (20 ft).

■ 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.

With a 50 Ω matched antenna all marine bands can­not be used. The following antenna matcher or an­tenna tuner may be helpful for antenna installation.

D MN-100/MN-100L ANTENNA MATCHERS

D AT-130 AUTOMATIC ANTENNA TUNER

D Non-Icom tuner

Some non-Icom tuners may be used with the IC­M700PRO. Please consult your dealer or marina if
you wish to connect one. The following internal set­tings may be required for connection.

ing [TUNE].

■ Mounting

R

WARNING:

NEVER mount the transceiver over-

head. The weight of the transceiver is approximately
8 kg., 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 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.

RCAUTION: 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.
