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

DISTRESS CALL PROCEDURE

1.“MAYDAY MAYDAY MAYDAY.”

2.“THIS IS ...............” (name of vessel).

3.Say your call sign or other description of the vessel (AND 9 digit DSC ID if you have one).

4.“LOCATED AT ...............” (your position).

5.State the nature of the distress and assistance required.

6.Give any other information which might facilitate the rescue.

Or, transmit your Distress call using digital selective calling on Channel 70.

USING DIGITAL SELECTIVE CALLING (Ch 70)

DISTRESS CALL PROCEDURE

1.While lifting up the key cover, hold down [DISTRESS] for 3 seconds until you hear 3 short beeps and then one long beep.

2.Wait for an acknowledgment on Channel 70 from a coast station.

• After the acknowledgement is received, Channel 16 is automatically selected.

3.Hold down [PTT], then transmit the appropriate information as listed above.

INSTALLATION NOTE

Installation:

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 the installation height should be at least 1.76 meters above any accessible position. 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 a distance of 1.76 meters of the antenna, nor operated at all if any person is touching the antenna.

It is recommended that antenna of a maximum gain of

3 dB is used. If higher gain antenna are required then please contact your Icom distributor for revised installation recommendations.

Operation:

The exposure to RF electromagnetic field is only applicable when this device is transmitting. This exposure is naturally reduced due to the nature of alternating periods of receiving and transmitting. Keep your transmissions to the minimum necessary.

ii

PRECAUTIONS

RWARNING! NEVER connect the transceiver to an AC outlet.

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

RWARNING! NEVER connect the transceiver to an external DC power supply directly. The transceiver must be connected to the DC power supply through the PS-310 dc- dc power supply that is sold as a set with this transceiver. Be sure to not connect with reverse polarity.

PS-310ʼs version	Input voltage	Output voltage
#01	21.6 to 31.2 V DC	12.6 V DC
#02	10.8 to 15.6 V DC	12.6 V DC

RWARNING! NEVER cut the DC power cable between the DC plug at the back of the transceiver/PS-310 and the fuse holder. If an incorrect connection is made, the transceiver may be damaged.

CAUTION: NEVER place the transceiver where normal operation of the vessel may be hindered, or where it could cause bodily injury.

KEEP the transceiver and microphone at least 1 meter away from the vessel’s magnetic navigation compass.

DO NOT place or leave the transceiver in areas with temperatures below –15°C or above +55°C, or in areas subject to direct sunlight, such as a dashboard.

DO NOT use harsh solvents such as Benzine or alcohol to clean the transceiver, as they will damage the transceiver’s surfaces. If the transceiver becomes dusty or dirty, wipe it clean with a soft, dry cloth.

BE CAREFUL! The transceiver rear panel will become hot when operating continuously for long periods of time.

Place the transceiver in a secure place to avoid inadvertent use by unauthorized persons.

BE CAREFUL! The transceiver’s front panel meets IPX7* requirements for waterproof protection. However, once the transceiver has been dropped, or the waterproof seal is cracked or damaged, waterproof protection cannot be

guaranteed because of possible damage to the case or the waterproof seal.

*The connectors on the rear panel do not meet IPX7.

If the front panel is exposed to saltwater, BE SURE TO CLEAN IT THOROUGHLY WITH FRESH WATER when the front panel’s waterproof protection is effective. Otherwise, the keys and switch may become inoperable due to salt crystallization.

DDPriorities

•Read all rules and regulations pertaining to call 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 calls are prohibited under law.

DDPrivacy

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

•Indecent or profane language is prohibited.

DDRadio licenses

(1) SHIP STATION LICENSE

You may require a current radio station license before using the transceiver. It is unlawful to operate a ship station which is not licensed, but required to be.

If required, contact 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.

	OPERATING RULES	1
	(2) OPERATOR’S LICENSE			1
			2
	A Restricted Radiotelephone Operator Permit is the license
	most often held by small vessel radio operators when a		3
	radio is not required for safety purposes.
			4
	If required, the Restricted Radiotelephone Operator Permit
			5
	must be posted or kept with the operator. If required, only a
	licensed radio operator may operate a transceiver.		6
	However, non-licensed individuals may talk over a		7
	transceiver if a licensed operator starts, supervises, ends		8
	the call and makes the necessary log entries.		9
	A current copy of the applicable government rules and		10
	regulations is only required to be on hand for vessels in		11
	which a radio telephone is compulsory. However, even
	if you are not required to have these on hand it is your		12
	responsibility to be thoroughly acquainted with all pertinent		13
	rules and regulations.

■■Scan types

You can find ongoing calls by scanning the Favorite channels without rotating [CH/ENT].

The GM600 has two scan types.

•Priority scan (default)

•Normal scan

PRIORITY SCAN

A Priority scan sequentially scans all Favorite channels while also monitoring Channel 16.

	CH 01	CH 02
CH 06	CH 16	CH 03
	CH 05	CH 04

When a signal is received:

• On Channel 16

The scan pauses until the signal on Channel 16 disappears.

• On a channel other than Channel 16:

The scan switches to Dualwatch, until the signal disappears.

Before you start a scan:

•Set the desired channels you want to scan as Favorite channels. (Scans only Favorite channels.) (p. 21)

•Set the desired scan type to “Normal" or “Priority.” (p. 77)

NORMAL SCAN

A Normal scan sequentially scans all Favorite channels. However, the scan does not check Channel 16 unless it is set as a Favorite channel.
