8 CALL PROCEDURE ■ Position request call The position request call is used to confirm the specified ship’s position. This calling system uses digital signals only, therefore a voice reply is not necessary. Confirmation screen DSC WATCH screen 2 4 6 8 12 16 RX ACK MMSI 123456789 12.345.0 F1B GPS Lat 34 34'N SP Lon135 34'E 12:34 Exit ***** Position REQ ***** --------- Call --------To:IC-M801_1 Category:Safety Call Freq:TX 2187.5kHz RX 2187.5kHz Call Push and hold for 1 sec.
8 ■ Test call Testing on the exclusive DSC distress and safety calling frequencies (such as 2187.5 kHz) should be avoided as much as possible by using other methods. When testing on the distress/safety frequency is unavoidable, it should be indicated that these are test transmissions. Normally the test call would require no further communications between the two stations involved. DSC WATCH screen 2 4 6 8 12 16 RX Call frequency selection ACK MMSI 123456789 12.345.
9 WHEN RECEIVING A CALL ■ To receive a DSC call The independent built-in DSC receiver circuit in the ICM801GMDSS scans all distress/safety frequencies, therefore, the “distress,” “urgency” and “safety” calls on those frequencies can be decoded at all times. However, “routine” and “group” calls on the other frequencies are received via the transceiver’s receiver circuit. Therefore, the transceiver must set to DSC watch mode by pushing [DSC] to decode these calls.
9 ■ Received information When receiving a DSC call, the received format specifier and its contents are memorized into the received call log. Distress calls (including other calls with a distress category) are stored separately from other calls. Up to 20 distress and up to 20 other calls can be memorized. q During DSC watch mode, push [RX CLAR] to enter the received DSC memory select screen. t Push [ENT] to selects the traffic screen and monitor the traffic frequency.
9 WHEN RECEIVING A CALL ■ Deleting a memory ➥ When the desired memory contents to be deleted are displayed as at right, push and hold [CE] for 1 sec. • After erasing, the receive memory select screen, as in step e of “■ Received information,” is selected automatically. • The DSC memory, which 48 hours or more have been passed from received, can only be deleted.

13 CONNECTION AND INSTALLATION ■ Advanced connections 24 V battery Position and UTC time data (IEC61162-1:2000) Printer (IBM® centronics or compatible) Remote controller Modem, NBDP (Narrow Band Direct Printing), FAX systems CAUTION: Any connected external unit, such as printer, etc., must be properly grounded. We suggest using a wide copper strap. (p.
13 ■ Ground connection The transceiver and antenna tuner MUST have an adequate RF 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 50 or 75 mm (2 or 3 inches) wide copper strap and make the connection as short as possible.
13 CONNECTION AND INSTALLATION ■ Power source The transceiver requires a regulated DC power of 26.4 V and at least 30 A. • Direct connection to 24 V battery in your ship through the supplied DC power cable. R WARNING! NEVER connect the transceiver to a battery using reverse polarity. This will damage the transceiver. CATION: Before connecting the transceiver main unit to a battery, make sure the transceiver input voltage suits to the battery voltage.
CONNECTION AND INSTALLATION 13 ■ 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 will not be matched with the transceiver antenna connector. R DANGER: HIGH VOLTAGE! NEVER touch the antenna element/wire while tuning or transmitting. Antenna wire AT-141 • Ferrite core attachment Attach the supplied ferrite core to the antenna tuner receptacle as the illustration below.
13 CONNECTION AND INSTALLATION ■ Mounting D Mounting location Select a location that provides easy access to the controller for navigation safety, has good ventilation and is not subject to sea spray. The controller should be at 90 degrees to your line of sight when operating it. DMounting the controller/speaker 56 CAUTION: KEEP the transceiver and handset or microphone at least 1 meter away from your ship’s magnetic navigation compass.
CONNECTION AND INSTALLATION D Mounting angle attachment q Attach the supplied rubber feet to the mounting angle, if desired. 13 w Attach the mounting angles using with the supplied hex head bolts (M6×15), flat and spring washers as illustrated below. Hex head bolt (M6×15) Spring washer Flat washer Mounting angle D Mounting the main unit Hex head bolt (M6×50) Spring washer Flat washer R WARNING! NEVER mount the transceiver main unit overhead. The weight of the unit is approximately 8.
13 CONNECTION AND INSTALLATION ■ Using the optional MB-108 The optional MB-108 mounting bracket is available for mounting the transceiver’s main unit. The MB-108 allows you to one-touch attachment/detachment capabilities. q Attach the mounting handles with the supplied hex head bolts (M6×15), spring and flat washers as below. CAUTION! WEAR GLOBES when installing the MB-108. Edges of the MB-108 may be sharp and may easily cut your fingers, hands, etc.
13 ■ Using the optional MB-75 The optional MB-75 flush mount is available for mounting the controller and speaker to a flat surface such as an instrument panel. CAUTION: KEEP the transceiver and handset or microphone at least 1 meter away from your ship’s magnetic navigation compass. q Using the template on the page 67 for the remote controller (RC-25GMDSS), and page 69 for the speaker (SP-24E), carefully cut a hole into the instrument panel (or wherever you plan to mount the controller or the speaker).

ANTENNAS & TUNERS If your Icom SSB transceiver is going aboard a sailboat, you may either use an insulated backstay an insulated sidestay, or a non-resonant white fiber glass whip antenna off the stern to make up your antenna system. Your best range will be from an insulated backstay because of the long length of the antenna “radiator” which is that portion within the top and bottom insulators. Have your rigger put the top insulator about at least 3 feet down from the tip of the mast.
17 ANTENNA AND GROUNDING CONSIDERATIONS everything of ground potential. If you can get at your keel bolt, or tap a screw into the keel, your grounding is done. Lead incapsulated keels are the ultimate in grounds, and you may need nothing further. In powerboats, since there's no keel, you’re going to need to come up with at least 100 square feet of RF ground surface below the water line. This means you must pick up as many ground potentials below the water line as possible.
terline ground system and attached directly to each piece of low and high frequency radio gear. While this may also seem to be an insurmountable problem in running foil, rather than wire, foil handles quite nicely, even in tight places. The foil is easily soldered to the below waterline ground system, and then routed up the side of the hull into the area of the NAV station. It may be glassed into the hull, painted over, glued in, or even left resting on the side of the hull.
