transceiver.

SAVE THIS INSTRUCTION MANUAL. This

manual contains important safety and operating in­structions for the IC-M801GMDSS.

EXPLICIT DEFINITIONS

R WARNING HIGH VOLTAGE! NEVER at-

tach an antenna or internal antenna connector during
transmission. This may result in an electrical shock or
burn.

R WARNING! NEVER connect the transceiver to

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

R WARNING! NEVER mount the transceiver

main unit overhead. The weight of the unit is approxi­mately 8.5 kg, but its apparent weight will increase
several fold due to wave shocks or vibration. The unit
must be mounted on a flat hard surface only.

R NEVER connect a power source of more than

31.2 V DC. This connection could cause a fire or ruin
the transceiver.

R NEVER place the transceiver where normal oper-

ation of the ship or vehicle may be hindered or where it
could cause bodily injury.

R NEVER let metal, wire or other objects touch any

internal part or connectors on the rear panel of the
transceiver. This may result in an electric shock.

DO NOT use chemical agents such as benzine or al­cohol when cleaning, as they can damage the trans­ceiver surface.

During maritime mobile operation, KEEP the trans­ceiver and handset or microphone as far away as pos­sible

(at least 1 m) from the magnetic navigation com-

pass to prevent erroneous indications.

Use Icom handset or microphones only (supplied or op-

tional)

. Other manufacturer’s handset or microphones
have different pin assignments, and connection to the
IC-M801GMDSS may damage the transceiver.

AVOID using or placing the transceiver in areas with
temperatures below –15°C or above +55°C.

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.

Place the unit in a secure place to avoid inadvertent
use by children.

BE CAREFUL! The transceiver main unit will become
hot when operating the transceiver continuously for
long periods.

OPERATING RULES AND GUIDELINES

1

Quick Reference

Before transmitting, monitor the channel you wish to
use so as to avoid interrupting transmissions al­ready in progress.

• CALL PROCEDURE

Calls must be properly identified and the time limit
must be respected.

q Give your call sign each time you call another ship

or coast guard station. If you have no call sign,
identify the station by giving your ship name and the
name of the licensee.

w Give your call sign at the end of each transmission

that lasts more than 3 min.

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

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

r Keep your unanswered calls short, less than

30 sec. Do not repeat a call for 2 min.

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 signals are prohibited

and punishable by law.

• PRIVACY

q Information overheard but not intended for you, can-

not lawfully be used in any way.

w Indecent or profane language is prohibited.

• LOGS

q All distress, emergency and safety calls must be

recorded in complete details. Log data activity is
usually recorded in 24 hour time. Universal Time
Coordinated (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 ship 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 the 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 reg­ulation handy.

Using scan function

The transceiver has automatic channel or frequency
change capability (scan function). There are 3 types
of scan functions available to suit your needs.

Channel scan and channel resume scan increase
channels within a 20 channel range, such as Ch 1 to
Ch 20, Ch 141 to Ch 160, etc., in user channels; or
all channels in the group of ITU channels.

Programmed scan scans frequencies within the fre­quency range between user channels 159 and 160.

Scan type selection is available in initial set mode.
See p. 46 for the selection.

SCAN OPERATION

q Rotate [GRP] and [CH], or use the keypad to se-

lect your desired channel group.

• This operation is not necessary for programmed scan.

w Push [F] then [2

SQL

] to turn OFF the squelch

function, if programmed scan is selected.

e Push [F] then [3

DD

Squelch function

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

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

➥ Push [F] then [2

DD

Noise blanker

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

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

➥ Push [F] then [1NB] to switch the function ON and

OFF.

• See page 45 for the noise blanker level adjustment.

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

[1 NB][F]

DD

AGC OFF function

The receive gain is automatically adjusted according
to 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.

➥ Push [F] then [5

[5 AGC×][F]

DD

RF gain setting

The receiver gain can be reduced with the RF gain
setting. This may help to remove undesired weak sig­nals while monitoring strong signals.

Usually, the AGC function reduces the RF gain ac­cording to the receive signal strength and these weak
signals are removed. However, during no signal re­ception, these weak signals may not be heard.

In such cases, the RF gain may be useful for setting a
minimum level at which to hear signals.

q Push [F] then [6RF-G] to select the RF gain set

mode, as shown below.

w Rotate [CH] to set the desired minimum cutting

level.
