Training Information (valid for TU5160)

The System 5000 MF/HF is designed for “occupational use only” and is also classified as
such.
It must only be used in the course of employment by individuals aware of both the hazards
as well as the way to minimize those hazards.
The radio is thus NOT intended for use in an uncontrolled environment by general public.
The System 5000 MF/HF has been tested and complies with the FCC RF exposure limits for
“Occupational Use Only”. The radio also complies with the following guidelines and
standards regarding RF energy and electromagnetic energy levels including the
recommended levels for human exposure:

• FCC OET Bulletin 65 Supplement C, evaluating compliance with FCC guidelines for
human exposure to radio frequency electromagnetic fields

• American National Standards Institute (C95.1) IEEE standard for safety levels with
respect to human exposure to radio frequency electromagnetic fields, 3 kHz to 300
GHz

• American National Standards Institute (C95.3) IEEE recommended practice for the
measurement of potentially hazardous electromagnetic fields – RF and microwaves

Below the RF exposure hazards and instructions in safe operation of the radio within the
FCC RF exposure limits established for it are described.

Warning:

Your radio set generates electromagnetic RF (radio frequency) energywhen it is transmitting.
To ensure that you and those around you are not exposed to excessive amounts of that
energy (beyond FCC allowable limits for occupational use) and thus to avoid health hazards
from excessive exposure to RF energy, FCC OET bulletin 65 establishes an Maximum
Permissible Exposure (MPE) radius of 6" (1.8m) for the maximum power of your radio (150W
selected) with a whip antenna having a maximum gain of 3.0dBi.
This means all persons must be at least 6" (1.8m) away from the antenna when the radio is
transmitting.

Installation:

1. A whip antenna with a maximum power gain of 3 dBi must be mounted at least 12.6"
(3.9m) above the highest deck where people may be staying during radio transmissions.
The distance is to be measured vertically from the lowest point of the antenna. This
provides the minimum separation distance which is in compliance with RF exposure
requirements and is based on the MPE radius of 6" (1.8m) plus the 6.6" (2.0m) height of
an adult.

2 On vessels that cannot fulfil requirements in item 1, the antenna must be mounted so

that its lowest point is at least 6" (1.8m) vertically above the heads of people on deck and
all persons must be outside the 6" (1.8m) MPE radius during radio transmission.

• Always mount the antenna at least 6" (1.8m) from possible human access

• Never touch the antenna when transmitting

• Use only authorized T&T accessories

3. If antenna has to be placed in public areas or near people with no awareness of the radio
transmission, the antenna must be placed at a distance not less than 12" (3.6m) from
possible human access.

Failure to observe any of these warnings may cause you or other people to exceed FCC RF
exposure limits or create other dangerous conditions.

1 MF/HF Fundamental info

Propagation of MF and HF Radio Waves.

MF/HF radiocommunications provide a medium and long range service. The 1.6-4 MHz
marine band is intended primarily for coastal operation beyond normal VHF communication
range. A reliable range of more than 150 nautical miles can be expected in most areas in the
daytime, more in the nighttime. Propagation of the radio waves in this band is mainly by
ground waves i.e. the waves from the transmitter aerial follow the earth’s curvature to the
receiver aerial. The high frequency range 4 - 30 MHz can provide communication for
hundreds or even thousands of nautical miles. The long range is achieved by sky waves
reflected from the ionosphere. Propagation of the radio waves depends on a number of
factors such as frequency, time of day, time of year, and solar activity. The channels
allocated to the maritime mobile service in the HF range are divided into a number of bands:
4, 6, 8, 12, 16, 18, 22, 25 MHz to allow a suitable frequency band to be selected for commu­nication dependent on distance and time of day.

Radiotelephony

The mode of emission used for telephony transmissions in the marine bands is SSB (single­sideband, J3E). On the international distress frequency 2182 kHz compatible AM (amplitude
modulation, H3E) may be used in addition for communication with non-GMDSS ships. AM
mode is used also when receiving broadcasting. The frequencies for radiotelephone distress
and safety traffic in the HF bands are 4125 kHz, 6215 kHz, 8291 kHz, 12290 kHz, and 16420
kHz. Working frequencies for public correspondence with coast stations are arranged in pairs
for duplex/semi-duplex operation. For the HF bands these channels are allocated numbers
by ITU on an international basis. In addition a number of simplex frequencies are available in
each band for ship-to-ship communication.

Radiotelex

Marine telex is also referred to as (NBDP) ‘Narrow Band Direct Printing’. Due to the narrow
bandwidth of the transmissions, a longer range may be expected compared to radiote­lephony. The frequencies for radiotelex distress and safety traffic are 2174.5 kHz, 4177.5
kHz, 6268 kHz, 8376.5 kHz, 12520 kHz, and 16695 kHz. Working frequencies for public
correspondence with coast stations are arranged in pairs. For the HF bands these channels
are allocated numbers by ITU on an international basis. In addition a number of simplex
frequencies are available in each band for ship-to-ship communication.

Basic

DSC

DSC (Digital Selective Calling) is an automatic calling system which allows a specific station
to be contacted and made aware that a station wishes to communicate with it. In addition to
calls to specific stations the system can also be used to call groups of ships and this is of
significance for its use for DSC distress alerting. DSC is an alerting signal only and the
communication which follows the call is made on an appropriate frequency band using
radiotelephony or radiotelex. The frequencies for DSC distress and safety calling are 2187.5
kHz, 4207.5 kHz, 6312 kHz, 8414.5 kHz, 12577 kHz, and 16804.5 kHz. Calling frequencies
for public correspondence with coast stations are arranged in pairs, both international and
national frequencies are assigned. In addition the frequency 2177 kHz may be used for ship­to-ship calling.

• Release the PTT key to listen.

• When answered:
Follow the instructions from the coast station. The coast station may ask for further
identification, information on position and next port of call, and may suggest another
working channel for the traffic to follow. If the coast station is not ready to receive traffic
immediately it may ask you to wait for a specific number of minutes.

PTT only when you are talking. If on a simplex channel (in other words, a channel
that can carry only one transmission at a time), always say “Over” just before

3.2 Listening for calls from a coast station

Coast stations transmit traffic lists consisting of call signs/names of the ships for which they
have traffic.
The traffic lists are sent at specified times and at intervals of typically two hours. They are
broadcasted on the normal working frequencies from the coast station. Ships should, as far
as possible, listen to the traffic lists transmitted by relevant coast stations. On hearing their
call sign they should establish communication as soon as they can do so.

1. Select the appropriate station.

2. Select the channel on which traffic lists are transmitted.

3. Switch loudspeaker on and adjust volume to an appropriate level.
On HF verbal traffic lists are transmitted in more frequency bands simultaneously. Search for

Press to connect

Ships receiving a distress alert from another ship should prepare for receiving the subse­quent distress communication on the telephony distress frequency in the same band in which
the DSC call was received.

Wait for a short interval in order to give a coast station time to acknowledge the DSC distress
alert first. Then, if within range and able to assist, acknowledge the receipt of the distress
alert by radiotelephony:

Press the handset key and say:

• the distress signal MAYDAY;

• the words THIS IS;

• the NAME of the vessel in distress, spoken three times;

• the NAME or other identification of own ship, spoken three times;

Direct Dial Calls:

Some coast stations provide automatic connection from the public switched telephone
network allowing a telephone subscriber to call the ship directly without operator intervention
at the coast station.

Note: Auto Acknowledgement must be On to allow automatic connection, see DSC Status
Display.

An acknowledgement is initiated immediately when a Direct Dial call is received. The
handset should be lifted off hook within 1 minute which will initiate a DSC call on the working
frequency. This call is used by the coast station for channel quality evaluation. When
acknowledgement is received telephone conversation can start.

When the handset is placed on hook after a Direct Dial call a DSC call indicating ‘End of call’
is send to terminate the connection. The coast station may respond with a DSC Call

4.12 Geographic Area Computation

When transmitting a geographical area call, the user is requested to enter the position of the
ship (x,y) and the radius of interest r. This information is transformed to a square with a
corner point and the length of its sides and . Finally the DSC message is
transmitted over the air. See the figure below for an illustration of the relation between the
user input (the white circle) and the information transmitted over the air (the grey square).

The center point is the position of the ship measured in degrees and minutes, whereas the
radius of interest is given in nautical miles.

The corner point of the square and the length of its sides is given in degrees. Note that these
values are rounded to degrees, and due to the requirement that the square shall include the
entire circle; this will result in a slightly larger area than defined by the user input.

Also note that special handling is required when close to the poles. If the latitude of the
corner point is transformed to a value greater that 90° then is set to 90° and the length of
the square is reduced correspondingly. If the length of the square is greater than 90°
then is set to 90°.
