vessel. Compact fist microphone makes for convenient operation of the
equipment
Other featur es of the radio includes:
lAccess to all available International channels (currently allocated).
lAllows 10 memory channels for quick recall and memory scan.
lProvides as many as 20 user programmable names with MMSI, 10 distress
calls and 20 individual calls for DSC communications.
lRotary volume control with power on/off, rotary channel selector and rotary
squelch adjustable knob give you more convenient operation of the radio.
lOutstanding performance of waterproof complying with Japanese Industry
Standard level 7.
l23watts high output power allows you make contact with others in a long

re-place the mounting bracket on the surface aligning the drilled holes;
4. Insert the four fixing screws and secure the bracket to mounting surface
using the supplied bolts, spring washers, plain washers and nuts;
LCaution: if you can not reach behind the mounting surface to attach the nut on
the bolts, use the supplied self-tapping screws to fasten the bracket.
5. Insert the four fixing screws and fasten them with a Philip screw driver with
attention not to screw too tightly;
6. Mount the base station onto the bracket with notice of the matching of the
protuberances on the both inner side of the bracket and the pits on the two

DIGITAL SELECTIVE CALLING
5.1 INTRODUCTION
5.1.1 DIGITAL SELECTIVE CALLING (DSC)
Digital Selective Calling is a semi-automated method of establishing a radio call,
it has been designated by the International Maritime Organization (IMO) as an
international standard for establishing VHF, MF and HF radio calls. It had also
been designated part of the Global Maritime Distress and Safety System
(GMDSS). It is planed that DSC will eventually replace aural watches on distress
frequencies and will be used to announce routine and urgent maritime safety
information broadcasts. This new service will also allow mariners to initiate or
receive distress, urgency, safety and routine calls to or from another vessel
equipped with a DSC transceiver.
5.1.2 MARINE MOBILE SERVICE INDENTITY (MMSI)
An MMIS is a nine digit number used on Marine Transceiver capable of using
Digital Selective Calling (DSC). This number is used like a telephone number to
selectively call other vessels. Refer to section 6.12 (USER MMSI ENTRY).
5.2 DSC MENU NAVIGATION
Once in DSC mode, the Channel/Select key is used to select items within the
DSC Send Call menu. Rotating the Channel/Select knob selects successive
items within the DSC Menu (and subsequent sub-menus). When the Menu list
contains more items than will fit on the LCD, the list scrolls to reveal additional
items. Pressing the Channel/Select knob enters (or acts) the selected function.
At any time while in DSC Mode, pressing and releasing the DSC key returns the
screen to the DSC Send Call menu and aborts the current operation. Pressing
any other mode key (BAND, MEM ) while in the DSC Mode aborts the DSC

Page 21 Page 22
function (except a Distress Call) and changes to the Mode of operation
accordingly.
5.3 SENDING A DSC CALL
5.3.1 DISTRESS CALL

display “flash” in sequence with the “beeps”.
If DISTRESS button is released before 4 seconds, the initiation of distress
call is not activated and you should press 16 key to exit and return to VHF
mode; IfDISTRESS button is pressed for more than 4 seconds, DISTRESS
call is sent whether channel 70 is busy or not. When Distress is sent, the
display ceases to flash, the acoustic alarm goes to a continuous tone until
acknowledgement received or press any key is pressed to terminate the
acoustic alarm
During the distress call sequence, the Distress Cancellation menu is present
in the Text Area of the Display. See step 5.3.1.2 to cancel.
During the distress call sequence, the radio simultaneously watches Channel 70
for a DSC Acknowledgement and Channel 16. When the distress call is
acknowledged, the acoustic alarm stops and the display returns to normal VHF
operation on Channel 16, with High power selected. If no acknowledgement is
received, the unit retransmits the DISTRESS call at random intervals of 3.5 to 4.5
minutes whether Channel 70 is busy or not until a response is received or the call
is manually cancelled. By pressing 16 Key button, the radio returns to normal
VHF.
