The information in this manual is provided for information purposes only, is subject to change without notice, may contain errors or inaccuracies, and represents no commitment whatsoever. This agreement is governed by the laws of Denmark. Doc. No.: B5022GB0 ii Issue: F/0549 Training Information The Thrane & Thrane RT5022/RT5020 VHF radio 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 RT5022/RT5020 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 Thrane & Thrane radio set generates electromagnetic RF (radio frequency) energy when 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 3” (0.9m) for the maximum power of your radio (25W selected) with an half wave omni-directional antenna having a maximum gain of 3 dB (5.2dBi). This means all persons must be at least 3” (0.9m) away from the antenna when the radio is transmitting. Installation: 1. An omni-directional antenna with a maximum power gain of 5.2 dBi must be mounted at least 9.6” (2.9m) 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 3” (0,9m) plus the 6.6” (2m) 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 3” (0.9m) vertically above the heads of people on deck and all persons must be outside the 3” (0.9m) MPE radius during radio transmission. • • • Always mount the antenna at least 3” (0.9m) 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 6” (1.8m) 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. 0549 iii Quick DSC distress call (only for emergency use) 1. If necessary, switch on by pressing the ON/OFF button 2. Lift up the lid covering the orange key and press for 5 seconds. 3. The Alarm indicator light will flash and will be accompanied by a sound. Distress message is sent at the continuous tone. 4. Unless stopped manually, by pressing the key or switching the unit off, the distress call is automatically repeated every 3½-4½ minutes until distress acknowledgment is received. Wait for distress acknowledgement and start mayday procedure. If an alarm panel is connected the VHF DISTRESS button on this unit will have the same functionality. All further handling should continue in front of your main VHF DSC. NOTE: If needed the default language (English) is obtained by pressing the following keys: Mayday procedure When DSC distress acknowledgement is received after you have pressed DISTRESS, or if you otherwise need to commence distress traffic via radiotelephony on the distress traffic frequency channel 16, follow this procedure: • • • • • • “MAYDAY”, “this is”, the 9-digit identity and the call sign or other identification of the ship, the ship’s position in latitude and longitude or other reference to a known geographi cal location, the nature of distress and assistance wanted, any other information which might facilitate the rescue. Upon reception of a DSC distress alert from another ship in distress, you should acknowledge the receipt by radiotelephony on the distress traffic frequency channel 16, by doing the following: • • • • iv “MAYDAY”, the 9-digit identity of the ship in distress, repeated 3 times, “this is”, the 9-digit identity or the call sign or other identification of own ship, repeated 3 times, “RECEIVED MAYDAY”. 0549 Your VHF at a glance (RT5020/RT5022) Alarm Call DW 1W 15 16 10 Int US BI Tx SQ Vol 0191 - 05 11 13 14 Loudspeaker Volume level indicator Squelch level indicator Indicator lamps.

communication in brief 1.1 Powering VHF The VHF is turned on by a single press on the ON/OFF/Volume button. The VHF is turned off by pressing the ON/OFF/Volume button for 3 seconds. Always indicated by a count down window in the information display, except if the radio is powered down in distress mode. Any connected devices (Alarm Panel, Handset, CUs) will be operational only if the VHF is powered. 1.2 Operating VHF radio communication The VHF is operated by means of a handset. To bring the VHF 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. Receive mode is always reached by releasing the PTT button. Release PTT PT Press PTT Handset hooked off PT Handset hooked on Transmit and receive is performed on the working channel shown in the telephone display. If the handset is used with an RT5020 duplex radio, received signal can always be monitored in the handset earpiece. With the RT5022 simplex/semi-duplex radio the received voice signal can only be monitored in the earpiece while PTT is released. 1.3 Receiving a call on Channel 16 When you hear your call name in the loudspeaker: 1. Lift the handset. 2. Press the PTT key. 3. Repeat the name of the station calling you and say “This is [your ship’s name].” 4. Suggest a channel other than 16 by saying “Channel [suggested number]”. 5. Say “Over” and release the PTT key to allow your caller to confirm the suggested new channel. 0544 Basic Basic 6. Switch to the new channel – for example, channel 71 – and begin your conversation. Press PTT only when you are talking. If you are on a simplex channel (in other words, a channel that can carry only one transmission at a time), always say “Over” just before releasing. With duplex channels (ship-shore calls), the conversation can be two-way as with a normal land telephone calls. 1.4 Making a radiotelephone call A radiotelephone call is preferably to be commenced using DSC. Alternatively the following public calling procedure shall be used: 1. Select channel 16 (by pressing ) or other agreed channel. 2. Lift the handset. 3. Press the PTT key and make your call. First, say the name of the station you are calling three times. Then say “This is [your ship’s name”], again three times. Finally, say “Over”. 4. Release the PTT key to listen. 5. When answered, agree upon a channel, switch to that channel – for example, channel 6 – and begin your conversation. Press 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 releasing. 1.5 Speaker volume The volume in the loudspeaker (internal and optional external) is adjusted by turning the VOLUME control. The volume level is visualized in the telephone display. The volume can be adjusted to a mute mode by turning the volume control left (down). If the volume is adjusted to the mute level the VOL LED will flash. 1.6 Earpiece volume The volume level of the default handset earpiece is adjusted by selecting the Handset Volume menu (4.3.1). The and buttons are used to adjust the level. The level is indicated in the information/message display. 1.7 Squelch The squelch level is adjusted by using the squelch control. The actual squelch level is visualized in the telephone display. 0544 Channel selection Basic 1.8 The system is defaulting to channel 16 after a normal power-on. Channels can be selected using the (increasing to next valid VHF channel) or (decreasing channel). Channels can also be entered using the numeric keypad. The active working channel is always shown in the upper display. 1.9 Dual watch Dual watch is a mode where the priority channel (16) is scanned periodically for a signal while listening on a working channel. Dual watch is activated by pressing the DW button. The DW indicator is lit while DW is active. Dual watch is deactivated by: • • • • Pressing DW – Continues to receive on the working channel. Pressing PTT – Transmits always on working channel Pressing ´16´. Pressing Replay - Dual watch is terminated while the message is replayed and will then be re-invoked Selecting a new channel while in dual watch mode will continue dual watch on the new selected working channel, unless a signal is found on channel 16. 1.10 Replay Replay is a facility built into the product which always will allow the operator to repeat the latest 90 seconds of received voice data to be replayed in the acoustic devices. Received voice data is defined when the squelch is open. This means that 90 seconds of actual traffic could be accumulated over several hours/days. If the 90 seconds storage limit is reached the oldest data is simply overridden with the newest received traffic data (FIFO principle). Activating replay The front panel has a dedicated replay button. A push on the replay button will bring up a (replay) window in the information/message display. Holding down replay will drive a counter to be updated in the display where it is determined how many seconds of recorded data is wanted for replay - the last XX seconds of recorded data. If pressing the replay button in normal receive mode this will still allow the unit to receive audio in the speaker system. 0544 Basic When releasing the replay button the replay function will take over the audio system and start to replay the last XX seconds of data received on any channel. The time when the traffic was received and the channel on which it was received is displayed during replay. Volume control can be used on the replay data to adjust sound pressure in audio devices. During replay “— —” is shown in the channel display, to indicate that listening on the live receive signal is disabled in this situation (as well as recording is disabled). If a signal is received on the working channel while replay is activated, this is indicated in the lower left corner of the replay window. Replay is interrupted when: • • Pressing Pressing PTT • Receiving any message in the information/message display or Recorded voice data will not survive power-down of any kind. 1.11 Dimming To adjust the light intensity the dim button is pressed. While the dim button is pressed the intensity is changing. Releasing the dim button will maintain the current light intensity. A renewed pressing of the dim button will change the direction of the light intensity change. If the VHF is dimmed to zero, any key press will wake up the light to a minimum visible at night. Active text in the information/message display might prevent dimming to zero. It is possible to reduce illumination to zero. If you press a key in this state the light will illuminate to the lowest illuminated state for 5 seconds, where after it will return to the zero illumination state. If a message is shown on the screen while dimming is set to zero, the illumination is adjusted to the lowest nonzero value. 1.12 Contrast Contrast of the information/message display (and thereby optimizing the vertical viewing angle) can be adjusted initially by entering the Display Contrast menu. Use the arrows to adjust contrast. The contrast will be set simultaneously during adjustment. 0544 2 Basic DSC operations 2.1 Basic When switched on, your VHF automatically monitors channel 70 for incoming DSC calls. Menu operation To operate DSC functionality the menu system is used. The main menu can be activated by pressing . From the main menu all parts of the menu tree can be reached (see chapter: Menu tree). All menus have a unique hierarchical number. The main menu is the only menu which does not have a number. The number is (to a certain level) displayed in the upper right corner of the screen. If more than 6 items are available in the menu, arrows will indicate if remaining items are to found above ( items. ) current items or below ( The active menu item is highlighted. A press on ) current displayed menu or will move the focus. will select the item which is currently in focus. A press on A press on any of the numeric keys (1 to 9) in a menu will quickly select the menu item having the corresponding number. A press on will return to the previous menu window (normally one level up). If is pressed in the main menu, the menu will be turned off. Selecting the menus for transmitting DSC calls will lead to a sequence of windows (flows). The flow sequences are controlled by the (accept and proceed to next window) or (cancel and return to the previous window) buttons. Following a menu hierarchy or a window flow might include a guidance text (e.g. “OK/next” ). Certain windows and lists do not show any guidance texts. These windows can always be left by window). 2.2 (jumping to main menu) or (returning to the previous Receiving a DSC call An incoming call will always be recognized by activity on the CALL indicator – and if more severe (Distress and Urgency calls), also the ALARM indicator. When receiving a DSC call the message will be displayed immediately in the information/message display, if not obstructed by any other operations taking place. Received DSC calls will always be accompanied by a sound alarm. 0544 Basic When you receive a call you can read in the display whether the call is addressed to All Ships, ships in a specific geographic area, a group of ships or to your ship (identified by your MMSI number) as an individual call. If you are busy you can choose to handle the call a little later (e.g. by pressing which will stop the alarm sound. When you are ready to accept the call, lift the handset or press handling the particular call will now appear. Follow the instructions. ), . Your choices If an individual call is received it will not be acknowledged before you accept the call. 2.3 Transmitting DSC Calls All DSC calls are initiated from the DSC Call Menu (1). When entering a menu item, you will be guided through the call construction. For every call generated you will have the possibility of verifying the call before you transmit it. 2.4 Alarm Call DW 1W Int US BI Tx SQ Vol DSC Call 1 Station Call 2 PSTN Call 3 Group Call 4 Emergency 5 DSC Logs Call a ship station To call a ship station and suggest a working channel, enter the Station Call menu (1.1) and follow the instructions. Have the ships MMSI number ready if it is not available via the contact list. Please also refer to Section 4.1.2 for using extended sub-addressing. 2.5 Call a shore station To call a shore station, enter the Station Call menu (1.1) and follow the instructions. Have the shore MMSI number (00*) ready if it is not available via the contact list. 2.6 Direct call to a PSTN via a coast station This kind of calls requires automatic/semi-automatic support from the coast station, and is available only within some countries. If the service is not available, you will need to make a simple shore station call and request the connection via radiotelephony. To make a direct phone call to a PSTN or a mobile phone, enter the direct phone call menu (1.2) (PSTN Call) and follow the instructions. Have MMSI number (00*) for a reachable shore station ready if it is not available via the contact list, as well as the public phone number you would like to request. 2.7 Call a group of ships To call a group of ships enter the Group Call menu (1.3) and follow the instructions. Have the group MMSI number (0*) ready if it is not available via the contact list. 0544 Create emergency calls In the category of emergency calls (1.4) you will find the following menu: Transmitting any of these calls should be done with caution. Please make yourself familiar to the common procedures for using these calls. Emergency 1.4 1 Compose Distress 2 Compose Urgency 3 Compose Safety 4 Compose Relays 5 Compose Distress Ack Selecting any of the call types will lead to a call establishing flow with maximum flexibility. You should make yourself familiar with the flow sequences, but be sure you do not actually the transmit verificasend the message by mistake. In other words, never press tion window if you do not actually intend to send an emergency call. Designated distress calls are composed entering the menu (1.4.1). From this list the Nature of Distress is selected. A fast method to reach this selection list is a short press on The call completion is then continued from here. If no nature of distress is selected, but is pressed for 5 seconds, an undesignated distress is sent. Distress calls are always transmitted by pressing the button for 5 seconds. After you have transmitted a distress call the VHF is in distress mode (distress call is re-transmitted once each 3½-4½ minutes). The distress mode can be exited only by reception of the appropriate distress acknowledgement call or if you press for 5 seconds, or if you power off the VHF. The VHF will start up in distress mode after a power failure. 2.9 DSC call log Received and transmitted DSC messages can be found with details in the DSC Logs (1.5). A special log contains distress related calls. The call log system will store the last (20) calls sorted by date and time. DSC Logs 1 DSC Distress Log 2 DSC Receive Log 3 DSC Transmit 1.5 Each of the logs and each of the calls within the logs have their own possible actions upon selection (e.g. printing). 2.10 Entering your position into the system Ship’s position and the time for this position are essential to the success of a possible rescue operation. This information is automatically added to a DSC distress call sent from your VHF. Therefore it is important always to keep this information updated. Normally a GPS is connected to the VHF. In case of correct installation this will assure correct updating of position and time. If your VHF is not connected to an external GPS system, or a malfunction of the GPS connection is detected by the VHF, the VHF will automatically prompt you to update your position manually 1 minute after power-up and then every 4 hours. The position and time can always be entered on your initiative via the Set Position & Time selection in the Settings menu (4.1.1). 0544 Basic 2.8 3 Your VHF in detail 3.1 Abnormal power-down If for any reason the main power disappears for a period less than 10 minutes, the VHF will be able to turn itself on when power is resumed (without pressing ON/OFF). Detail If the VHF was abnormally powered down for less than 1 minute, the VHF will start up with the same settings as before the power failure took place (communication channel, volume, squelch settings, etc.). If the abnormal power down lasted more than 1 minute the VHF might start up with the settings as they were last time the VHF was turned off normally. 3.2 Settings All volume settings are stored as default during the power off sequence. 3.3 Automatic squelch programming It is possible to attach a squelch level with each channel if particular noisy channels require continuous special squelch setting. If a channel is selected squelch level is inherited from either the global setting or a stored squelch level for that particular channel (default is that all channels are using the global squelch level). Storing squelch level on a channel is done while listening on that particular channel: • Push the button. • The squelch level is now automatically adjusted to suppress the noise on the channel. While adjusting, noise is heard. The squelch level indicator follows adjustment, and finally display the required level. The squelch level is memorized on the channel, indicated by flashing the SQ LED (flashing 3 seconds). If a channel with a programmed squelch level is selected and the SQUELCH button is turned the programmed squelch level for that channel is removed (global level). During Dual Watch or Scanning only the global squelsh level is used (as indicated by the squelch level indicator). Channel 16 squelch level is not programmable. All programmed channel squelch levels are stored during power down and restored during power-up sequence. 10 0544 3.4 Setting channel mode The selected country region is stored during power down sequence. Using the country region BI (Inland waterways) Dual Watch (DW) and scanning mode are not available. 3.5 Private channels Private channels can be defined by using the service interface only (distributor/dealer). Enabled private channels become valid for selection on the front panel. Using the will simply make the private channel number appear above the highest numeric channel number. 30 (3x10) private channels are available for each enabled channel mode. Note: In US mode private channels P0-9 will be pre-programmed with the 10 weather channels. In CA mode, P0-2 is pre-programmed with the 3 regional weather channels. Private channels can be selected using the numeric key pad: • Private channels: Long press on followed by a digit (0-9) • Leisure channels: Long press on followed by a digit (0-9) • Fisher channels: Long press on followed by a digit (0-9) Continued activation of the keys ´3´, ´5´ or ´7´ will cause the letters F-, L- or P- respectively to be displayed. 3.6 Duplex channels If duplex channels are selected on an RT5022 simplex/semi-duplex radio (see chapter: Maritime channels) the VHF will operate in semi-duplex mode meaning that the VHF is operated in simplex mode, but uses two different frequencies to receive and transmit. If a duplex channel is selected on an RT5020 duplex radio full duplex is supported on these channels, meaning that both receiver and transmitter is active simultaneously. 0544 11 Detail The VHF is delivered from factory with both Int. & US channels enabled for selection from the operation menu. Provision of other country regions (channel tables) for selection requires the intervention by an authorized Sailor representative in order to enable such. The operator selection of preferred country region (channel table) is done from menu 4.4.1 (channel mode) and the selected country region is indicated in the front panel display (note: this does not apply to the CA channel table and any custom defined channel tables). 3.7 ATIS (inland waterways only) Detail ATIS is mandatory to use in inland waterways on e.g. the Rhine. ATIS is a digital data stream containing ships call sign coded into a DSC-like message, sent over the voice channel each time the PTT button is released. If PTT is continuously pressed ATIS is automatically sent each 5 minutes. ATIS is enabled automatically when BI is selected in menu (4.4.1). For purpose of operator comfort the received ATIS signal on the active voice channel will be muted. The ATIS call sign is programmable from the service interface or from menu 4.4.3. once. The format of the programmed ATIS code is entered according to the following call sign prefix conversion table: Character Phonetic Alpha Bravo Charlie Delta Echo Foxtrot Golf Hotel India Juliett Kilo Lima Mike Value 10 11 12 13 Character Phonetic November Oskar Papa Quebec Romeo Sierra Tango Uniform Victor Whiskey X-ray Yankee Zulu Value 14 15 16 17 18 19 20 21 22 23 24 25 26 I.e. a Dutch (MID-number 244) ship with call sign SP1234, should be programmed with the following number: 244P1234 with the digit 2 entered as the first digit, and the digit 4 as the last digit. 3.8 Transmitter power Transmitter output power can always be chosen while the radio is active. Pressing the 1W button will toggle the transmitter power between low power (below 1W) and high power (below 25W). The 1W indicator is lit when low power is selected. As a default any channel shift will cause the transmitter power to be adjusted to the maximum power allowed on that channel. 12 0544 3.9 Channel scanning Scanning is an extension to the dual watch functionality, by which it is possible to watch multiple channels. It is possible to scan: All channels in a sequence A number of selected channels in a sequence organized into individual 3 scan tables - Scan table A, B and C. The scan type can be selected from the Scanning menu (3). The DW indicator is lit as well (because the priority channel 16 by default is included in any scan table). During the scan “SC” is shown in the upper display. If an active signal is found on a channel different from channel 16 the radio remains on that channel for 4 seconds (but still respecting dual watch requirements), where after scanning is resumed. The telephone display is displaying the active channel. If an active signal is found on channel 16, the VHF is locked on channel 16 until the signal disappears, where after scanning is resumed. The telephone display is displaying the active channel (16). While the active scanning window is visible, scanning can be terminated by: • • • • • • Lifting the handset off the hook Pressing ´16´ - Channel 16 is used as working channel Pressing DISTRESS – Initiates DSC distress Pressing – Working channel is used as before scanning was entered (regardless of carrier state). Pressing Replay - Message is replayed Pressing any numeric key - Normal channel entry If scanning is terminated while no active signal was found, the VHF will receive on the working channel (as it was before scanning was initiated). If scanning is terminated (handset hook-off) while an active signal is received, the VHF will operate on this channel after termination. 3.10 Creating scan tables The scanning tables are user configurable. Creating or editing a scanning table by organizing a subset of channels (e.g. Table A) for scanning is done by selecting the Edit Scan Table A entry (3.5.1). Private channels (non-numeric identifiers – P, F or L) can be part of a channel table. The number of channels in a scan table is limited to 16. 3 scan tables (A,B & C) can be defined for each enabled channel mode. Scanning tables are stored during the power-down sequence. 0544 13 Detail • • 4 4.1 DSC operations in detail MMSI Number To operate VHF with DSC the equipment needs to be configured with your vessel’s MMSI number. If not configured before installation, the VHF will inform you to program the 9-digit MMSI number at start-up. Detail The vessel’s MMSI number is programmable from the DSC menu (4.5). It can be programmed only once from this menu after which changing of the programmed MMSI will be possible only through the service interface. If the MMSI number has been programmed correctly, the number is displayed in the default idle display after start-up. 4.1.1 Sub-Addressed MMSI The VHF supports setting the 10th digit of the MMSI number to a non-zero value. This is to be used for being able to individually address multiple VHF’s on board a single vessel (with the same 9-digit MMSI). The 10th digit of the MMSI number can be programmed by the operator. After programming the vessel MMSI number the 10th digit will always be set to 0. Programming the 10th bit is done via the menu (4.5.6.1) If the unit is configured to a non-zero X10 value, it will only respond to received individual routine calls matching all 10 digits in the MMSI number. Transmitted routine calls or acknowledgements to individual routine calls are using the self-ID with non-zero digit 10. If X10 is programmed to zero the unit reaction modes, if receiving an individual call with nonzero X10 in the address or self-ID, can be selected using the menu (4.5.6.2). Selecting 1 Acknowledge non-zero, the unit will receive the call. A call acknowledgement will be returned to exactly the same address as received in the self-ID (default after programming the MMSI number). Selecting 2 Acknowledge zero, the unit will receive the call. A call acknowledgement will be returned to address as received in the self-ID, but with X10 set to zero. Selecting 3 Reject call, will ignore the received call. 4.1.2 Using extended sub-address in a calling sequence Entering the station call menu (1.1) allows you to address an RT call request to another radio supporting the extended address format. If the receiver MMSI is not a coast station (00*), it is possible to enter either 9 or 10 digits in the Enter Receiver MMSI window. Entering 9 digits will automatically set the 10th digit to zero for the receiver address. All other call flows than RT station call requests to a ship station are not supporting this feature. It is possible to create entries in the contact list with 9 or 10 digit MMSI numbers, unless they are group station (0*) or coast station (00*) numbers. 14 0544 4.2 Group MMSI number If your radio is configured as member of a group(s) it will receive group calls to that group. The VHF can be configured to be part of (up to 10) groups. The group MMSI numbers can be programmed from menu 4.5.2. The configured group numbers are shown as a list. You can add a group MMSI number by selecting thelist entry and press . Enter a valid group MMSI and press A group number can be changed by selecting the number , edit the number and press OK. A group number can be removed from the list by selecting the number, press delete the number and press 4.3 Differentiating incoming calls by ringing tones Your VHF rings in various ways according to the nature of the call, as shown in the following diagram: TONE SIGNAL 5 sec. DISTRESS TRANSMIT 3 sec. Tx 3 1/2 - 4 1/2 min 3 sec. 3 1/2 - 4 1/2 min Tx 3 sec. Tx 3 1/2 - 4 1/2 min 3 sec. Tx 60 sec. DISTRESS & URGENCY SAFETY CALLS 1 sec. 8 sec. ROUTINE & PSTN 39717 If an individual call acknowledgement is received, an alarm tone is activated that is equal to the alarm tone used for receiving a call request of the same type. Calls that are not received as distress calls or calls with category distress or urgency will always engage the prescribed alarm sound. For any other DSC calls the call sound on reception can be enabled/disabled from a Setup menu (4.3.2). If you receive a call with an alarm sound, you will always be able to mute the alarm by pressing the button to be able to finish current radiotelephony call. This procedure will not affect the actual call accept procedure. 0544 15 Detail 4.4 Working channel A working channel will always be suggested by the system if a ship station or group is called for a routine call. The working channel is suggested by using the following procedure: Detail 1. 2. 3. 4. Select a random channel from the list of simplex channels Scan channel for traffic (open squelch) If the channel is free suggest the channel. If the channel is busy restart from 1. If no channels are found to be free within 1 second no channel is suggested. 4.5 Contact list The contact list or phone book can contain up to 200 entries. Each entry might contain: • • Station-, group-, coast station- or public name Station MMSI, group MMSI, coast MMSI and/or public phone number The contact list can be reached from the Contacts menu (2). 4.5.1 Contacts 1 Call Contact 2 Show Contact 3 Add Contact 4 Edit Contact 5 Delete Contact Calling a contact It is possible to initiate the following calls from the Call Contact menu item (2.1): • • • Individual station (ships or coast) routine radiotelephony calls Group routine calls Direct dial phone calls to a PSTN phone Entering the Call Contact menu item will bring up a list of possible names to select. The name list is sorted alphabetically. The alphanumeric keypad can be used for quick search on the first letter in the contact name (using wheel mode). Selecting a contact will show data for the contact in question. Example: Call Contact Name: Peters Oil MMSI: 003456789 PSTN no: 0045 68098765 When is pressed the appropriate call generator will be initialized, based on the data. If a PSTN number exists for the selected contact the PSTN call flow is initiated. Therefore it is important the corresponding MMSI number for that contact being a coast station number. If only an MMSI number is present for the contact, a ship station, group or coast station call is initiated: 16 0544 • • If the MMSI number is a group number, the group call flow is entered from the window where a channel is selected. If a ship station number MMSI is available, the station call flow is entered from the window where a channel is selected. If the MMSI number is a coast station, the operator will be led to the transmit verification window for a station call. 4.5.1.1 Using the Contact list from the Call Sequences Any call initiated from the DSC call menu that needs an MMSI number or PSTN number, might search and use that number from the Contact list. If “Search for Contact” is selected from anywhere in a call flow the contact search list is entered. Selecting the contact with will return to the corresponding MMSI/PSTN entry window in the call flow with the selected number information pre-filled. 4.5.2 Show contact Via the menu item 2.2. it is possible to search for a contact’s information without changing or initiate anything. 4.5.3 Adding a new contact If you want to add a new contact to your list, go into menu item 2.3. The following empty contact window will appear: Add Contact Name: MMSI: PSTN: Save contact The focus bar is used to control what field the operator wants to put information into. Example if is pressed: Add Contact Name: Anders Fisker After having pressed looks as follows: the contact information Proceed with the necessary data entries. When finished move the focus bar to “Save contact” and press Add Contact Name: Anders Fisker MMSI: PSTN: Save contact As a minimum a contact name and a valid MMSI number must be entered. If a PSTN number is entered the MMSI number for that contact must be a valid coast station MMSI number (00*). 0544 17 Detail • See also Section 4.1.2 4.5.4 Editing the contact list Any contacts from the list can be edited using a similar principle as described above using menu item 2.4. Detail 4.5.5 Deleting a Contact Entry Any contact can be deleted from the contact list. If menu 2.5 is selected the contact can be searched for in the list. When found and selected with the contact will be removed from the contact list. 4.6 Settings for DSC The following sections describe the settings that can be applied to different call types. 4.6.1 Special calls The VHF is capable of supporting transmission of All Ships DSC urgency messages with second tele-commands: • • Medical transports Ships and Aircrafts These settings can be changed only from the service interface. Reception of these calls is always possible. If the VHF is configured for using these calls it will work in the following way: • • • 4.6.2 After powering up (normally) the VHF it will not be possible to use these call types (message: “Call type not enabled in VHF” if selected.) Each of the call types can be enabled via the menu 4.5.3. (the filled square indicates the call type that is enabled). After enabling the call property can be added in an All Ships Urgency call sequence. Automatic acknowledgement The VHF can be set to automatic acknowledgement of the following calls: • • • Safety position requests - Default disabled after power-up Safety test requests - Default enabled after power-up Routine polling requests - Default enabled after power-up After power-up the behavior can be changed from menu 4.5.4. The automatic acknowledgement (if enabled) will take place without informing the operator. The calls are stored in the receive/transmit log. The operator might experience a short interruption in functionality while the automatic acknowledgement takes place (e.g. scanning, dual watch). 18 0544 4.6.3 Automatic channel shift The VHF can be set to automatically changing the working channel on receipt of the following call types: • • • Individual radiotelephony acknowledgement with a valid channel information Radiotelephony group calls with valid channel information Radiotelephony all ship safety calls with valid channel information If enabled, a received call will start the (normally) periodic alarm only once. The channel will switch immediately after and the window is closed. The automatic channel shift is overruled (turned to manual acknowledgement - requiring press on OK or a hook-on to hook-off transition) if: • • Any handset is hooked off The received call cannot currently be presented on the information display (due to priority) Distress calls and all ship calls with category distress or urgency will alert continuously until manually handled from the front panel. 4.7 Implicit behaviour for operations with DSC This section describes assumptions and decisions made that are critical for correct functionality, but might be hidden to the operator in the display. 4.7.1 DSC transmission All DSC calls are transmitted on channel 70 with a transmitter power of 25W. Distress, urgency and non-test safety calls are always transmitted. Other calls are sent only if the radio is not already recognizing a DSC message on channel 70. 4.7.2 Transmitting undesignated distress Undesignated distress (solely created using the DISTRESS button) does not show any message prior to the actual transmission. The following message will be sent: Format specifier: Distress (112) Self-Id: Nature of distress: Undesignated (107) Distress coordinates: Automatically inserted if position is available (e.g. from GPS), otherwise unknown (9999999999) Time of position: Automatically inserted if time of position is available (e.g. from GPS), otherwise unknown (8888) Subsequent communication: 100 EOS: 127 0544 19 Detail The set-up is done via menu 4.5.5. The setting will survive powering off the product. 4.7.3 Verification of a DSC call before transmission The final step in each DSC call sequence is the verification window, in which it is possible to verify the call you are about to transmit. The VHF will by default display only information that you could influence in the call setup. Example: Transmit Station Call What is hidden to the user is that calls are formed MMSI: 001234567 according to the specifications ITU R.493-11. Detail For the example call (an individual station call request) the following information is not shown to the user: • • 1st tele-command: F3E/G3E Simplex TP EOS: Acknowledgement request (RQ = 117) OK/send
