INSTRUCTION MANUAL

MF/HF MARINE TRANSCEIVER

GM800

Thank you for choosing this Icom product. The GM800 mf/hf marine transceiver is designed and built with Icom’s state of the art technology and craftsmanship. With proper care, this product should provide you with years of trouble-free operation.

The GM800 has Class A DSC functions for Distress alert transmission and reception, as well as general DSC calls (Individual call, Group call Geographical call, Position Request call, Polling Request call, and Test call).

IMPORTANT

READ ALL INSTRUCTIONS carefully and

completely before using the transceiver.

SAVE THIS INSTRUCTION MANUAL — This

instruction manual contains important operating instructions for the GM800.

NOTE: This transceiver receives the frequency

range30kHz~500kHzintheJ3Emode,butit

has not been tested and Icom does not warrant the operation in this frequency range. Thus this transceiver does not conform to the permission of

thefrequencyrange415kHz~526.5kHzwhichis

permitted by the ITU Radio Regulations [3].

To stabilize the output frequency:

±10Hzfrequencystabilityrequiresawarminguptime

period. The warming up time period is within 30 minutes after turning ON the transceiver’s main power, and it differs depending on the output temperature.

IN CASE OF EMERGENCY

When your ship requires assistance, contact other ships and the Coast Guard by sending a Distress call using DSC (digital selective calling) on an Emergency frequency.

When immediate help is needed:

1. To send a Distress call, hold down [DISTRESS] for 3 seconds until the short beeps become one long beep.

2. Release [DISTRESS] and wait for an acknowledgment.

3. After receiving the acknowledgement call, hold down [PTT] on the microphone and send the following information.

1 “MAYDAY, MAYDAY, MAYDAY.”

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

3 “LOCATED AT . . . .(ship’s position).”

4 Give the reason for the distress call. 5 Explain what assistance you need. 6 Give additional information about your ship:

OPERATING RULES

• CALL PROCEDURE

Calls must be properly identied and the time limit

must be respected.

1. 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.

2. Give your call sign at the end of each transmission that lasts more than 3 minutes.

3. You must break and give your call sign at least once every 15 minutes during long ship-to-shore

calls.

4. Keep your unanswered calls short, less than 30

seconds. Do not repeat a call for 2 minutes.

5. Unnecessary transmissions are not allowed.

• PRIORITIES

1. Read all rules and regulations pertaining to

priorities and keep an up-to-date copy handy. Safety and Distress calls take priority over any other calls.

2. False or fraudulent Distress signals are prohibited and punishable by law.

• PRIVACY

1. Information overheard but not intended for you, cannot lawfully be used in any case.

2. Indecent or profane language is prohibited.

• LOGS

1. All Distress, Emergency and Safety calls must be recorded in complete details. Log data activity

is usually recorded for 24 hours. Universal Time Coordinated (UTC) is frequently used.

2. Keep adjustments, repairs, channel frequency changes and authorized modications affecting electrical operation of the equipment in the maintenance log. The entries requires signatures by the authorized licensed technician performing or supervising the work.

• RADIO LICENSES (1) SHIP RADIO STATION LICENSE

You need a current ship radio station license before using the transceiver. It is unlawful to operate a ship radio 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 identication for radio communication 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.

If required, the Restricted Radiotelephone Operator Permit must be posted or kept with the operator. If required, 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.

A current copy of the applicable government rules and regulations is only required to be on hand for vessels in which a radio telephone is compulsory. However, even if you are not required to have these on hand it is your responsibility to be thoroughly acquainted with all pertinent rules and regulations.
