is activated.
• To utilize the records, connect the HX870 to a PC and take the log data
from the radio by using the PC Programming Software YCE02 (the YCE02
may be downloaded through the YAESU website).
Logger operation alert:
 When the memory for log data becomes full, three beeps will sound and a
warning message will be displayed. Afterwards the logger does not operate

10 DIGITAL SELECTIVE CALLING (DSC)
10.1 GENERAL
WARNING
This HX870 is designed to generate a digital maritime distress and
safety call to facilitate search and rescue. To be effective as a safety
device, this equipment must be used only within communication range
of a shore-based VHF marine channel 70 distress and safety watch
system. The range of signal may vary but under normal conditions
should be approximately 5 nautical miles.
Digital Selective Calling (DSC) 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 has also been designated as part of the Global Maritime Distress and
Safety System (GMDSS). It is planned that DSC will eventually replace aural
watches on distress frequencies and will be used to announce routine and
urgent maritime safety information broadcasts.
This system allows mariners to instantly send a distress call with GPS position
(when connected to the transceiver) to the Coast Guard and other vessels
within range of the transmission. DSC will also allow mariners to initiate or
receive Distress, Urgency, Safety, Routine, Position Request, and Position
Report, Automatic Position Polling, and Group calls to or from another vessel
equipped with a DSC transceiver.
10.2 MARITIME MOBILE SERVICE IDENTITY (MMSI)
10.2.1 What is an MMSI?
An MMSI is a nine digit number used on marine transceivers capable of using
Digital Selective Calling (DSC). This number is used like a telephone number
to selectively call other vessels.
THIS NUMBER MUST BE PROGRAMMED INTO THE RADIO TO OPERATE
DSC FUNCTIONS.
How can I obtain an MMSI assignment?

WARNING
The MMSI can be inputted only once. Therefore please be careful
not to input the incorrect MMSI number. If you need to change

10.3 DSC DISTRESS CALL
The HX870 is capable of transmitting and receiving DSC distress messages
to all DSC radios. The HX870 may be connected to a GPS to also transmit the
latitude and longitude of the vessel.
10.3.1 Transmitting a DSC Distress Call
NOTE
To be able to transmit a DSC distress call an MMSI number must be
programmed, refer to section “10.2.2 Programming the MMSI”.
In order for your ships location to be transmitted, the internal GPS
must be activated.
Basic Operation
1. Lift the red spring loaded DISTRESS cover on the right side
of the transceiver, and press and hold the DISTRESS key.
The radio display will count down (3-2-1) and then transmit
the distress call. The backlight of the display and keypad
flashes while the radios display is counting down.
2. When the distress signal is sent, the transceiver watches for
a transmission between CH16 and CH70 until an acknowledgment signal is received.
3. If no acknowledgment is received, the distress call is
repeated in 4 minute intervals until a DSC acknowledgment
is received.
4. When a DSC distress acknowledgment is received, a
distress alarm sounds and Channel 16 is automatically
selected. The display shows the MMSI of the ship responding to your distress.
5. Press the PTT button and state your name, vessel name,
number of persons on board and the distress situation, then
say “over” and wait for a reply from the acknowledging ship.

Pausing a DSC Distress Call
After a DSC distress call is transmitted, the DSC distress call is repeated every
4 minutes until the call is canceled by the user or until the radio is turned on
and off again. The HX870 has provision to suspend (pause) the retransmitting
of the distress call by the procedure below.
1. After the distress call is transmitted, the radio
will show the top display to the right.
Looking at this display you will notice “TX

will re-transmit the DSC distress call.
2. To suspend re-transmitting the DSC call,
press the [PAUSE] soft key.
3. To resume counting down to transmit the

10.4 ALL SHIPS CALL
The all ships call function allows contact to be established with DSC equipped
vessels without having their MMSI in the individual calling directory. Also, priority
for the call can be designated as “Urgency” or “Safety”.
URGENCY Call: This type of call is used when a vessel may not truly be in
distress, but have a potential problem that may lead to a
distress situation. This call is the same as saying “PAN PAN,
PAN PAN, PAN PAN” on Channel 16.
SAFETY Call: This type of call is used to transmit boating safety information
to other vessels. This message usually contains information
about an overdue boat, debris in the water, loss of a navigation aid or an important meteorological message. This call is
the same as saying “Securite, Securite, Securite”.

10.5 INDIVIDUAL CALL
This feature allows the HX870 to contact another vessel with a DSC VHF radio
and automatically switch the receiving radio to a desired communications channel. This feature is similar to calling a vessel on CH16 and requesting to go to
another channel (switching to the channel is private between the two stations).
Up to 100 individual contacts may be programmed.
10.5.1 Setting up the Individual / Position Call Directory
The HX870 has a DSC directory that allows you to store a vessel or person’s
name and the MMSI (Maritime Mobile Service Identity Number) number associated with vessels you wish to transmit individual calls, auto polling, position
request, position report, and polling transmissions.
To transmit an individual call you must program this directory with information
of the persons you wish to call, similar to a cellular phones telephone directory.

10.6 GROUP CALL
This feature allows the user to contact a group of specific vessels (e.g. members
of a yacht club) using DSC radios with group call function to automatically
switch to a desired channel for voice communications. This function is very
useful for yacht clubs and vessels traveling together that want to collectively
make announcements on a predetermined channel. Up to 20 group MMSIs
may be programmed.
10.6.1 Setting up a Group Call
For this function to operate, the same group MMSI (Maritime Mobile Service
Identity Number) must be programmed into all the DSC VHF radios within the
group of vessels that will be using this feature. To understand Group MMSI
programming, first a ship MMSI has to be understood.
Ship MMSI: The first three digits called MID (Mobile Identity Group) of a ship
MMSI denote the country the ship registered for an MMSI. The last 6 digits are
specific to the ships ID.
Ship MMSI Example: If your MMSI is “366123456”, “366” is MID which denote
the country and “123456” is your ships MMSI.
Group MMSI:
 Group MMSI numbers are not assigned by the FCC or other organizations
licensed to assign ship MMSI numbers.
 The first digit of a group MMSI is always set to “0” by International rules. All
Standard Horizon radios are preset so when programming a group MMSI
the first digit is set to “0”.
 The USCG recommends programming the MID of a ship MMSI into the
Second, Third and Fourth digits of the group MMSI as it denotes the area
the ship is located in.
 The last 5 digits are decided upon by persons in the group. This is an important step as all radios in the group must contain the same group MMSI so
they can be contacted by each other. There is a chance that another group
of vessels may program in the same group MMSI. If this happens, simply
change one or more of the last 5 digits of the group MMSI.

10.7 POSITION REQUEST
Advancements in DSC have made it possible to poll the location of another
vessel and show the position of that vessel on the display of the HX870. This
is a great feature for anyone wanting to know the position of another vessel.
For example your buddy that is catching fish, or finding the location of a person
you are cruising with.
NOTE
The other vessel must have an operating GPS receiver connected to its
DSC radio and must not have its radio set not to deny position requests.
(Refer the section “10.5 INDIVIDUAL CALL” to enter information into
the individual directory).
10.7.1 Setting up a Position Request Reply
The HX870 can be set up to automatically (default setting) or manually send
your position when requested by another vessel. This selection is important if
you are concerned about someone polling the position of your vessel that you
may not want to. In the manual mode you will see the MMSI (Maritime Mobile
Service Identity Number) or persons name shown on the display allowing you
to choose to send your position to the requesting vessel.
