Introduction
Congratulations on your new SAILOR HC4500B MF/HF maritime radio telephone with built-in
DSC (Digital Selective Calling) system, fulfilling the highest international standards for
marine MF/HF communication and safety procedures. If connected to a GPS or other
maritime navigation system it can automatically include the true UTC time and your position
in its DSC distress messages. For an explanation of DSC, see page 2.
This SAILOR marine equipment is a part of the modular system 4000 which also includes a
HF single sideband radiotelephone.
SAILOR marine equipment is specially designed for the extremely rugged conditions on bord
a ship, based on more than 50 years’ experience with all kinds of boats, from small pleasure
crafts, over fishing boats working under all climatic conditions, to the biggest ships.
SAILOR ® is one of Europe’s leading manufacturers of maritime radiocommunication
equipment - a position which has been maintained by means of constant and extensive
product development. We have a worldwide network of dealers with general agencies in
more than 80 countries. All our dealers are specially trained to service all your SAILOR

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). AM mode is used when receiving broadcast transmissions. The international
distress frequency for radiotelephony in the MF band is 2182 kHz. 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. For the MF band ITU
number are allocated for Region I only. In addition a number of simplex frequencies are
available in each band for ship-to-ship communication.
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 ‘all ships’ and 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 is made on an appropriate working frequency using
radiotelephony. 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 ship-to-ship
calling.

Basic Functions
Switch Supply On/Off
Switches equipment on when pressed. Switches equipment off when
pressed for 2 seconds.
Start-up display is ‘Telephony’ with last used settings.
Note: The equipment should always be switched on while at sea in order to
maintain continuous DSC watch on 2187.5 kHz.
Switch Speaker On/Off
Switches loudspeaker on/off.
Switch to Telephony/DSC
Switches between Telephony display and DSC display.
Telephony Functions
Select 2182 kHz
Sets TX and RX frequency to the radiotelephone distress frequency 2182
kHz, selects SSB Telephony mode, sets Power level High, Squelch Off,
Speaker On and increases Volume if lower than a preset level.
Change Mode
Changes between ‘SSB TELEPHONY’, ‘AM BROADCAST’, and ‘DSC’:
Optionally ‘LSB’ and ‘SSB REMOTE’, if enabled.
In AM BROADCAST mode TX frequency is shown dimmed and transceiver
cannot be keyed.
Change Output Power
Changes between ‘HIGH POWER’ and ‘LOW POWER’
DSC calls are automatically sent in ‘HIGH POWER’.
‘LOW POWER’ cannot be selected on the six telephony distress frequencies.
Re-tune the ATU
Starts a TX tuning sequence.
TX tuning is done automatically the first time the transmitter is keyed on a
new frequency and before any DSC transmission.

Switch Squelch On/Off
Changes between squelch on, indicated in the Telephony Display by
‘SQUELCH’ and squelch off (no indication). When squelch is on the receiver
is muted in speech pauses.
Squelch is automatically set to off by a change of RX frequency except
during scanning.
Squelch is automatically set to on when scanning is activated and to off when
scanning is deactivated.
May be switched on and off during scanning.
Always off in AM and SSB Remote mode. In SSB Remote mode cotrol of the
transceiver via the TU SYS connector is enabled.

Select TX frequency, e.g. 3210.0 kHz:
Select RX + TX frequency, e.g. 3545.0 kHz, simplex:
Press simultaneously
Select channel, e.g. 1208:
Pressing the ENTER softkey is equal to pressing Enter.
Pressing the TX softkey copies TX frequency to RX.
Pressing the RX softkey copies RX frequency to TX.
Pressing the SWAP softkey interchanges RX and TX frequencies.
Pressing the softkey deletes last entry.
Pressing the CANCEL softkey resets the display.
