IMPORTANT

READ ALL INSTRUCTIONS carefully and completely before using the transceiver.
WHEN INSTALLING THE DSC UNIT
NEVER transmit a distress call when your vessel does not need immediate help. Distress calls can be used only in times of emergency. AVOID using or placing the transceiver in direct sunlight or
in areas with temperatures below 20C (4F) or above +60C (+140F).
SAVE THIS INSTRUCTION MANUALThis instruction manual contains important operating instructions for the IC-M59.
YOU MUST HAVE a DSC vessel ID in order to operate the optional DSC functions of the transceiver. See your Dealer for details.
DO NOT operate the transceiver without running the vessels engine. When your vessels engine is OFF and the transceiver is transmitting, the vessels battery will soon become exhausted. KEEP the transceiver out of the reach of children.

CAUTIONS

RWARNING NEVER
connect the transceiver to an AC outlet. This may pose a re hazard or result in an electric shock.
KEEP the antenna cable and DC power cable as far away
as possible from electrical pumps, generators and other electronic instruments to prevent instrument malfunctions.
KEEP the transceiver and microphone at least 1 meter away from your vessel's magnetic navigation compass.
RWARNING HIGH VOLTAGE! NEVER touch the antenna or an internal antenna connector during transmission. This may result in an electric shock or a burn. NEVER
iii connect the transceiver to a power source of more than 16 V DC. This connection will ruin the transceiver.

OPERATING RULES

D Priorities
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. You must monitor channel 16 when you are not operating on another channel. False or fraudulent distress calls are prohibited under law.

OPERATORS 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 near the transceiver 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, 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.

D Privacy

Information overheard but not intended for you cannot lawfully be used in any way. Indecent or profane language is prohibited.

D Radio licenses

SHIP STATION LICENSE When your craft is equipped with a VHF FM transceiver, 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. This license includes the call sign which is your crafts identication for radio purposes.

DIGITAL SELECTIVE CALLING

UX-120 required

I General
When an optional UX-120 DSC UNIT is installed, digital selective calling (or DSC) can be used via the IC-M59. DSC is a method of radio communications involving digital signals rather than the more conventional method of voice communications. The advantage of using digital communications over voice communications is that information (especially useful for distress calls and other urgent matters) can be preprogrammed into a radio and transmitted accurately. DSC TYPE Distress call In addition, when a GPS receiver (NMEA0183 ver. 1.5, 2.0 or 2.1) is connected, your vessels position and the current UTC time are transmitted together with the vessels identity when making a distress call. See p. 27 for unit installation.
DESCRIPTION This sends distress information which includes your vessels ID (and position data/UTC time when a GPS receiver is connected). Send under emergency conditions only. DSC acknowledgement will be received from a coast station after making a distress call. This is used to alert Coast stations (or other ships) when a vessel in distress is unable to do so. The IC-M59 can only receive this type of signal; not transmit.

REF. pgs. 13, 16 p. 16

Distress relay call All ships call
This is used for non-emergency situations. This signal includes information which allows a re- pgs. 14, 16 ceiving transceiver to automatically select a specied channel for voice communication. This allows you to send a signal to a specic vessel only. The vessels ID code must be prepgs. programmed in advance. Two kinds of acknowledgements (able to comply/unable to comply) 15, 17 are available (for sending or receiving) after an individual call. This is used for announcement to all ships in the specied areawhen a GPS receiver is p. 17 connected calls directed to areas other than yours are rejected. Receive only for the IC-M59.

Individual call

Geographical area call
I Distress call transmission
CAUTION: Distress calls may be transmitted under
conditions of emergency only i.e. your vessel is in danger of sinking and/or a persons life is in danger.
When a distress acknowledgement is received, emergency alarm sounds and channel 16 is automatically selected.

Two messages can be selected for acknowledgement: Able to comply.You can communicate with the calling vessel via the mic after a DSC connection. Unable to comply.You cannot communicate with the calling vessel after a DSC connection (e.g. operator leaves transceiver).

While monitoring channel 70 and an individual call is received:
Emergency alarm or beeps sound depending on the received category. BUSY RCV and Ind appear in the LOW RCV USA display. The channel specified by the calling station is automatically selected for checking the RCV USA channel condition (except when full automatic acknowledgement is selected). Proceed as follows on the next page according to your preset conditions. 17
When full automatic (FA) is selected in SET mode (p. 21):
The transceiver automatically replies to the call in one of two ways, depending on the TX auto acknowledge setting in ACK USA SET mode (p. 21).
When able to comply is set (Ab), the transceiver automatically transmits an able to comply acknowledgement and then selects the channel as specified by the calling station for voice communications.
