Introduction Congratulations on your new SAILOR CU5100 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. The transceiver is born with a 2187,5kHz DSC watch receiver forming an ideal system for MF GMDSS installations. The transceiver can easily be upgraded for 6 channel scanning DSC watch receiver and Telex operation to comply with MF/HF requirements in sea area A3.

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.

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.
2 Basic functions Powering MF/HF The MF/HF is turned on by a single press on the ON/OFF/Volume button. The MF/HF is turned off by pressing the ON/OFF/Volume button for 4 seconds. Always indicated by a count down window in the information display, except if the radio is powered down in distress mode.
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. Dimming To adjust backlight intensity the dim button is pressed. Change mode With the mode button different operation modes can be selected.
How to make a call to a coast station Wait until transmission of the traffic list has finished and the channel is free. Call the coast station on the working frequency on which the traffic list was received or as instructed by the coast station.
3 Voice call operation Operating MF/HF radio communication The MF/HF is operated by means of a handset. To bring the MF/HF in transmission mode the handset must be hooked off and the PTT button on the handset has to be pressed. Transmission is indicated by the lighted TX indicator.
Enter Rx/Tx frequency Press RX to enter a new Rx frequency. Enter the new frequency via the keyboard. Complete by pressing Enter. Pressing the ENTER softkey is equal to pressing OK Press TX to enter a new Tx frequency. Enter the new frequency and complete by pressing Enter. Pressing the Rx softkey copies Rx frequency to the Tx.
Channel entry 3.4.1 Select a channel The MF/HF control unit has all ITU channels preprogrammed in a channel table. These channels starts at Ch 241 and ends at Ch 2517. Channel 1 to 199 are reserved as user channels. Press Ch and key in an existing channel number. Complete by pressing Enter or by pressing the ENTER softkey.

Set answer back mode AUTO ACKNOWLEDGEMENT = ON: Transmission of acknowledgement is initiated automatically when a direct call, polling or position request call is received. AUTO ACKNOWLEDGEMENT = OFF: Manuel acknowledgement only. Direct calls initiated by the ship can be carried through; direct calls from coast stations cannot (factory default).
Receiving a Distress Call The DSC Watch Receiver keeps continuous watch on the distress and safety frequency 2187.5 kHz. Reception of a distress or urgency call is indicated by a specific sound signal which continues until a key is pressed. Additional DSC channels can be used if 6-channel scan has been enabled, see chapter “Watch keeping receiver”.
Receiving an Individual call When the transceiver is not used for traffic, scanning should be activated to keep watch on one or more DSC frequencies used for public correspondence and general ship-to-ship communication. Reception of an individual routine call addressed to the ship is indicated by a sound signal which continues until the call is acted upon.
Page 26
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.
Sending a test call This call type is intended for test of the DSC system on distress and safety frequencies. Press the Menu button.

Select the DSC Start transmission of frequencies the call Steps between DSC distress frequencies Transmission of a DSC call on MF/HF takes approx. 8 seconds. The coast station should answer the call by sending a DSC Acknowledgement within 4 1/2 minutes. No further communication is intended to take place.
Calling a coast station Press the Menu button and select 1. DSC CALL Select COAST STATION Select individual call type routine call type Some coast stations provide automatic connection with the public switched telephone network. To use this facility select PHONE NO and key in the telephone number. Otherwise: Key in the nine digit MMSI number of the wanted coast station.
Page 30
Select the DSC frequency Steps between DSC frequencies If the MMSI number is found in the station list, the frequencies are selected from the DSC frequencies of the station if any; otherwise from the list of non distress DSC frequencies. If DSC frequencies were selected from the Telephony display prior to the call these are default.
Direct Dial Calls: If a phone number was included in the call then immediately after reception of the acknowl- edgement the DSC call is repeated on the working frequency. This call may be used by the coast station for channel quality evaluation. If the channel quality evaluation indicates that communication will be satisfactory, the coast station sends a DSC acknowledgement and starts dialing the subscriber number.
