mount to your radio.

Page 11 Page12
3.4 MOUNTING THE RADIO
To mount the radio on your vessel:
1. Find a appropriate location defined in section 3.2;
2. Place the mounting bracket on the location surface, use a pencil to mark the
location of four holes where the fixing screws is to go into;
LCaution: Be careful to not drill through the mounting surface.
3. Remove the bracket, drill four holes smaller than the screw diameter, then
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.

protuberances on the both inner side of the bracket and the pits on the two
sides of the base station (the selectable pits on the sides of the radio allow
you adjust the direction of the radio face to satisfy your easy-to-read-and-
use, 150for each rotation and totally 450tolerance);
7. Attach the supplied mounting knobs from the two sides of the bracket to
fixing the base station securely.
LCaution: KEEP the radio and handset at least 1 meter away from any magnetic
devices such as compass on your vessel.

Page 13 Page14
The supplied universal mounting bracket allows you mount your base station
from overhead or on dashboard with a big scope of angle as many as 450.

DIGITAL SELECTIVE CALLING
5.1 INTRODUCTION

Page 19 Page20
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 6.11 (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 theChannel/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
function (except a Distress Call) and changes to the Mode of operation
accordingly.
