How to Make a Distress Call
Speak slowly, clearly and calmly. 1. Select VHF Channel 16. 2. Press microphone button: "MAYDAY MAYDAY MAYDAY." 3. "THIS IS [your ship ID]." 4. "MAYDAY [your ship name]." 5. Tell where you are what navigational aids or landmarks are near. 6. State the nature of your distress. 7. Give number of persons aboard and condition of any injured. 8. Estimate present seaworthiness of your ship. 9. Briefly describe your ship meters, type, color, hull. 10. "I WILL BE LISTENING ON CHANNEL 16." 11. End message by saying "THIS IS [ship name/call sign] OVER." 12. Release the PTT key and listen. Someone should answer. If not, repeat call, beginning at Item 3 above. WARNING The following types of communication are prohibited by the FCC: false distress calls; calls to any boat excluding emergencies and radio tests; calls to or from a vessel on land and obscene or profane language. Using obscene or profane language could result in a fine of up to $10,000. 4
Section 2: Basic Radio Operation
This section addresses the radios basic operations, which includes MMSI (Maritime Mobile Service Identity) number setup. If you already have your MMSI number programmed into the radio and have a strong understanding of the radio's basic functions, move on to Section 3: Advanced Radio Operation.
The Lowrance LVR-850 VHF Marine Radio.
We're going to kick off the operation section with a brief description of the radio's basic functions. That will be followed by some important information on Digital Selective Calling and basic instructions on how to make and receive calls.

Using the Keypad

The keypad has eight keys: H/L (Hi/Lo), WX (Weather), 16/9 (Priority Channels), SCN (Scan), MEM (Memory), CALL (Call) and , the up-anddown arrow keys. When you press any of the keys a tone will sound. If you push a key and a 3-beep tone sounds, there is an error or the function is not supported by the radio. Youll notice several functions require you to hold down a key for a few seconds. In those cases, a single beep sounds, then, after a few moments, a second beep will be heard to let you know you have successfully changed the mode. 5

Power/Volume The volume knob at the top right of the radios face is used to power up the LVR 850. Turn the knob clockwise to turn on the radio. The unit will start on Ch. 2, then switch to Ch. 16, its default priority channel. Squelch Squelch, the bottom knob on the radios face, helps the unit screen out radio traffic resulting from signals that are too weak to transmit anything but noise. To adjust the squelch, turn it to the left until noise can be heard. Turn it back to the right until the noise is eliminated.

H/L (High/Low) The H/L key gives you control over the radio's wattage. The high-end is 25 Watts. The low-end is 1 Watt. If the LO ANNUNCIATOR is off, the radio will transmit at 25 Watts. WX (Weather) Dark clouds on the horizon? Press the WX key to enter the WX (WEATHER) MODE and get the latest weather information. Use the keys to change the WX channel. 16/9 (Priority Channel) The 16/9 key is used to switch between priority channels. It also allows you to exit various operation modes, ignore incoming calls and cancel outgoing calls. NOTE Ch. 16 and Ch. 9 may only be used to make initial contact with a vessel and nothing more. When there is an emergency, all Distress calls will be broadcast on Ch. 16. SCN (Scan) The SCN (scan) key allows you to monitor numerous channels at the same time. Scanning options include: PRIORITY SCAN, MEMORY SCAN AND

ALLSCAN.

MEM (Memory) The MEM key may be used to initiate a Memory Scan and gives you the option of adding or deleting channels from the radio's scan list memory. CALL By pressing the CALL key you can make a new call, return the last incoming call, place a call to all ships or to one of up to 10 stored MMSI numbers from a saved directory. DISTRESS By lifting up the red cover and holding down the DISTRESS button for three seconds, you will send a distress call to the Coast Guard and any other ship within range of you. Arrow Keys Use the keys to scroll through the channels and various menu options. PTT (Press to Talk) The PTT key is the talk button on the microphone. Press and hold it down to talk when making or receiving a call.

DSC Calling vs. non-DSC Calling
The LVR-850 supports two types of calls, Digital Selective Calls (DSC) and non-Digital Selective Calls. A non-DSC call is the traditional method where an individual hails another vessel on Ch. 16, then asks the other party to switch to a working channel set aside for the desired communication type. Once they have left Ch. 16 and the selected working channel is clear, the individual hails the vessel again to initiate communication. What is a DSC call? A relatively new technology, digital selective calling (DSC) gives you the capability to dial another boat directly via the vessel's MMSI (Maritime Mobile Service Identity) number, which functions much like a phone number. Digital Selective Calling simplifies the calling process, because you don't have to hail the vessel on Ch. 16 nor do you have to verbally direct them to the working channel you want them to switch to for communication. When their DSC radio receives your call, it automatically will switch to the channel you selected for communication. The primary reason DSC was created was to enhance boater safety. It does this in several ways. When working in tandem with a GPS unit, it helps the Coast Guard respond more quickly to a Distress Call, since the location of the vessel in distress will be automatically transmitted when the signal is sent out. It will automatically repeat a distress signal every four minutes. That would come in handy if, as in the case of a 7
fire, you could not man the radio and fight the fire at the same time. DSC calling also helps cut back the transmission traffic on Ch. 16, the emergency priority channel. How DSC works A digital selective call uses a digital signal to transmit a pack of information that can include, the callers MMSI number, the MMSI of the ship or ships being called, call priority and a frequency or mode request. Location and time of location may be entered manually or if an active GPS unit is attached, transmitted automatically. DSC calls allow you to contact a specific ship, a group of ships, a specific group of DSC receivers, ships in a particular geographic area or all ships within range of you. A DSC call may even be patched into a regular phone line through a commercial coastal station. One of the key elements of a DSC call is the ability to place an individual call directly to another vessel. Simplex or Duplex References to simplex and duplex channels are scattered throughout this manual. Simplex channels transmit and receive messages on the same frequency. Like a CB radio, only one message can be transmitted at a time. A duplex channel transmits and receives messages on different frequencies. Like a telephone, it gives users the capability to transmit and receive messages at the same time. You must choose a simplex channel when making a DSC call!

MMSI (Maritime Mobile Service Identity)
Your Maritime Mobile Service Identity number (MMSI) is like a home phone number. Other DSC (Digital Selective Calling) radios must enter your number before they can contact you. But first, you must program your number into your radio. If your MMSI number is not set up, the ID ANNUNCIATOR will blink on the display. CAUTION You only have one chance to program your MMSI into your radio. Study this section carefully to ensure the MMSI is entered correctly.
The figure above illustrates the MMSI number entry of 992344513.
If a valid MMSI is already stored in the radio's memory, you will not be able to enter a MMSI number. If a 9-digit MMSI number has not been programmed into the radio, you will not be able to make or receive DSC calls. To enter your assigned MMSI number, follow the steps listed in the MMSI Setup below. Warning Again, there is only one chance to do this procedure correctly, so go over this section carefully. MMSI Setup 1. Hold down the CALL key for 5 seconds. The ID ANNUNCIATOR will blink and a large "0" will be displayed alongside a small 16. The big number 0 is the MMSI digit you are entering and the small digit 16 is the first MMSI character field position. For example, a small digit "2" represents the 2nd number from the left in your assigned MMSI. If the number was "4" it would mean the big digit you were entering was the 4th number from the left and so on.
This example gives us a closer look at a number sequence from a MMSI entry. The big numbers are the MMSI digits. The small numbers in the lower right hand corner represent the digits' character field position. The big digit 4 is the sixth number from left in the MMSI. The big digit 5 is seventh from left and the big digit 1 is eighth from left.
NOTE You need only to modify the big (MMSI) digits. The small digits (character field position of the MMSI digit) will be generated automatically. 2. Use the keys to enter the first digit of your MMSI number, then press the MEM key to advance to the second digit. The small digit now displays the 2nd character position with a big-digit "0" and small-digit "2. Press the keys to set the second MMSI digit and touch the MEM key to store. Repeat the operation until all 9 digits have been entered. After inputting your MMSI, press the MEM key to double-check each digit. NOTE If there is an error in the entry procedure, press the 16/9 key to exit. You can also turn off the radio to ensure the MMSI won't be stored. After you are satisfied with the MMSI number you have entered, hold down the CALL key for 5 seconds to store the number. The ID ANNUCIATOR will stop blinking and the radio reverts to the main screen. Now you are ready to make a DSC call.

Choosing a Channel

Before making a call to another vessel, check the VHF chart in the back of this manual. You'll have to choose a simplex communication channel authorized for the type of communication you desire.

Making a Call

The LVR-850 supports five DSC call types: ALLSHIPS CALL, DIRECTORY CALL, LAST CALL, NEW CALL and DISTRESS CALL. The example below details a NEW CALL. For information on the other call types, see page 13. To place a DSC call

New Call

1. Select a simplex channel and press the CALL key once. LAST blinks. 2. Use the keys to select NEW CALL. 3. Press the CALL key again. You can now enter the MMSI data of the vessel you want to contact. 4. Use the keys to enter the MMSI numbers, pressing MEM after each digit. After completing MMSI entry, press the MEM key to verify each number of the MMSI. 5. Press the CALL key and the radio will transmit the request. If there is no ACK after 4 seconds, the radio transmits the call again. The radio will stay in standby mode until an ACK is received, indicated by the flashing ID Annunciator. If an ACK is not received, you can press the 10
call key again and the call is placed again. You can exit the call function at any time by pressing the 16/9 key twice. CAUTION Before transmitting, monitor the selected simplex channel to make sure it is clear. This is a FCC requirement.

Ch. 8 is simplex working channel
For more in depth information on placing calls see page 13. To place a non-DSC call: When making a non-DSC call, you'll have to switch to a communication channel after making initial contact, so be sure to select a channel authorized for the type of communication you desire. 1. Select an appropriate communication channel. 2. Tune your radio to Ch. 16 or Ch. 9. Speak slowly and clearly, stating the name of the vessel you are trying to contact followed by "this is (your ship name and call sign)." 3. When the other vessel responds, say "go to (the desired channel number) over." 4. Switch to the other working channel. After you are sure it is clear, call out to the other vessel, stating the vessel's name, followed by "this is (your ship name and call sign)."

Receiving a Call

Reception of an individual call automatically establishes communication on the working channel requested by the caller. Your radio transmits an ACK (Acknowledgement) message back to the calling radio. If 11
the calling vessels MMSI matches a number stored in your directory, the number's directory location is shown. If no match is made, the ID ANNUNCIATOR blinks. If you want to respond to the calling vessel, just press the PTT button on the microphone. Press the 16/9 key to ignore the call. See page 18 to get more detailed information on call reception.

Section 3: Advanced Operation
This section will give a more detailed explanation of what your radio can do. We'll start off with a breakdown of the types of DSC calls the LVR-850 can transmit and receive. That will be followed by a brief description of how to place a non-DSC call. If you are comfortable with your knowledge regarding transmission and reception of calls, skip ahead to page 20 to see how to set up a MMSI Directory. On page 27, there is information on the radio's weather function.
Transmission The five DSC calling modes are: 1. AllShips Call: places a call to any ship in range of you. 2. Directory Call: dials number from MMSI directory. 3. Distress Call: executes an emergency call to Coast Guard and other ships in range of you. 3. Last Call: dials last incoming call. 4. New Call: places call to caller not in the MMSI directory. Press CALL then use the keys to scroll through the four choices (DISTRESS CALL is a separate function, so it is not included in the calls menu). The LAST CALL option always appears first.

Four call sources to use

AllShips Call
This feature gives you the option of placing a call to all ships within range of you. NOTE This radio does not handle AllShips urgency or safety DSC calls.

AllShips calls use Ch. 6

1. Press the CALL key. 2. Use the keys to select ALLSHIP. 3. Press the CALL key to transmit. 13

Directory Call

See page 20 to learn how to setup a MMSI directory. To call a number from your directory: 1. Use the keys to select a simplex-working channel. 2. Press the CALL key. 3.Use the keys to select the call type DIR, LAST, NEW or ALLSHIPS. Select DIR, then press CALL. 4. Use the keys to choose a MMSI location number (1-10). The default number is the MMSI of the last used call. 5. Press the CALL key to transmit. The called radio will acknowledge and a communication link will be established. Just press PTT to talk. In the following example, Ch. 8 was used to call a MMSI stored in directory No. 3.

Choose directory mode

Waiting for ACK
ACK blinks until PTT is pressed
When the ACK ANNUNCIATOR turns on, the calling channel has been tuned in and a communication link established. Press PTT to talk.

Distress Call

In an emergency situation, lift the red cover on the front panel to make a Distress call to the Coast Guard. Press and hold the DISTRESS key for 14
three seconds. The radio switches to Ch. 16 and a three-second on screen timer begins to count down in the bottom right corner of the screen. When it reaches zero, the call is sent out. To stop the call, let go of the DISTRESS key. No message will be sent unless the timer counts down to zero. Press the 16/9 key to cancel. NOTE If an inadvertent Distress call is sent out, make sure you're on Ch. 16 and quickly transmit a message to all vessels, canceling the Distress call.

3-second timer

If the DISTRESS key is held down until the timer expires, the radio will switch to Ch. 70 and a distress call will be sent out. The DSC Distress message is transmitted at 25 watts. The Distress message contains your MMSI, your position and the UTC time acquired from your GPS, if you're using a GPS unit. The DISTRESS ANNUNCIATOR is displayed during the transmission.
Distress Message being sent

Timer expired

A loud 2-tone alarm sounds. This alarm cannot be stopped unless the mode is canceled. Pressing the 16/9 or PTT key cancels the DISTRESS WAITING MODE. If the mode is not canceled, the radio transmits the Distress message again every 4 minutes. A DISTRESS WAIT message will be displayed on the screen.
NOTE The Coast Guard is the only agency allowed to acknowledge a Distress call. An individual vessel's DSC radio will not automatically respond with an acknowledgement. 15
When an ACK is received, the distress mode is automatically canceled and communication will be on Ch. 16.

Last Call

You can send a last call by following this sequence: 1. Use the keys to select a simplex-working channel. The radio will default to Ch. 16 if a duplex channel is selected. (If you press the call key during WX CHANNEL MODE, the last used channel is displayed.) 2. Press the CALL key. 3. LAST blinks.
Last Call Last caller is No.4 in Directory
4. Press the CALL key to transmit. If there is no last call information stored, an error beep sounds. If the last call is a MMSI number stored in your directory, the number's directory location will be displayed below the ID ANNUNCIATOR. After the radio you're calling acknowledges the call, communication will be established as soon as you press the PTT button.
This procedure allows you to place an individual call. 1. Press the CALL key once. LAST blinks. 2. Use the keys to select NEW CALL. 3. Press the CALL key again. You can now enter the MMSI number. NOTE: New call MMSI numbers are not stored. They are for temporary use. You must enter them into your directory to have the numbers stored permanently.
NEW and ID Annunciators will blink

4. Use the keys to set proper MMSI data for the digit shown. After correct verification of the first digit of the MMSI number, touch the MEM key to advance. The small digit now displays the 2nd character position with a "0" as the big digit and "2" as the small digit. Set the second MMSI digit using keys and touch the MEM key to store. Repeat the operation until all 9 digits have been entered. Double-check your MMSI entry, toggling through each individual digit by pressing the MEM key. There is no backup or edit mode, so if you make a mistake entering the number, you'll have to start over. Press the 16/9 key to exit or just turn off the radio. After you are satisfied with the new MMSI number, press the call key. 5. Press the CALL key and the radio will transmit the request. If there is no acknowledgement (ACK) after 4 seconds, the radio transmits the call again. The radio will stay in standby mode, indicated by the flashing ID Annunciator, until an ACK is received. If an ACK is not received, you can press the call key again and the call is placed again. You can exit the call function at any time by pressing the 16/9 key twice. To place a non-DSC call: When making a non-DSC call, you'll have to switch to a communication channel after making initial contact, so be sure to select a channel authorized for the type of communication you desire.

GPS Annunciator

H/L The H/L key gives you control over the radio's wattage. The high-end is 25 Watts. The low-end is 1 Watt. If the LO ANNUNCIATOR is off, the radio will transmit at 25 Watts. Some channels do not accept transmissions or are restricted to a 1-Watt level. If you come across one of those channels and you try to switch to 25W, you will hear a 3-tone error beep, meaning you either can not transmit on that channel or it only accepts transmissions at the 1W (Lo) level.
Memory Operation Normally, the MEM ANNUNCIATOR appears on the display to alert the user the channel is stored in the memory channel list. The following figure shows Ch. 8 is stored in memory. 22
You can easily add or delete channels from the memory channel list. For your safety, DO NOT delete priority Ch. 16. To add a new channel, use the keys to select the desired channel (shown above in big digits). If the channel is currently stored as a memory channel, the MEM ANNUNCIATOR will be displayed. To add a new channel to the list, hold down the MEM key until the MEM ANNUNCIATOR appears. The new channel is now added to the list. To delete a channel from the list, use the keys to choose a channel saved in the memory list. You will know a channel from the memory list has been chosen when the MEM Annunciator appears on the screen. Hold down the MEM key for three seconds to delete the channel. The MEM ANNUNCIATOR no longer will be displayed when the channel is tuned in. NOTE To clear and reset all the memory channels, hold down the MEM key while turning on the radio. This clears all memory channels with the exception of the Priority Channel. Position Send/Request

Transmission

Your radio can send and receive information on location if it is connected to a GPS unit. This will allow you to locate a vessel without transmitting messages back and forth. To send your position (P1): 1. Press the CALL key, then use the keys to select DIR from the main screen and press Call. 2. To edit or enter the P1 memory location, use the keys to select position P1 from the directory. P1 will be displayed in the bottom right corner of the display. If the P1 location has CL in the window, you must enter the MMSI of the vessel to which you're trying to send your position. Press MEM and use the keys to enter the MMSI numbers, pressing MEM after each digit has been entered. When finished, press and hold the CALL key for five seconds. The screen will show FL P1, letting you know the MMSI is now stored in the P1 location. The MMSI number will be stored in the P1 location until you edit or replace the MMSI information. 23

With a quick press of the 16/9 key the priority channel immediately is selected with high (25W) transmission power. Press the 16/9 key again and it selects the last used channel. PTT (Push To Talk) This key is on the microphone. Press and hold it down to send a transmission. There is a 5-minute maximum transmission timer, per FCC regulations. Scan There are three primary scanning modes, ALLSCAN, MEMORY SCAN, and PRIORITY SCAN. 25
NOTE Remember, you cancel any scan mode at anytime by pressing the 16/9 or SCN key.

To start an All Scan

To scan through all available channels, press and hold the SCN key for three seconds. ALL SCN will appear on the display. The radio now will scroll through every available channel as it scans.
A noisy channel that interrupts the scanning can be temporarily eliminated from the scan list by holding down the MEM key. The channel receiving the signal will be skipped, allowing the scanning to continue uninhibited. Turning the radio off and on again will restore all the channels back to the ALLSCAN memory list.

To start a Memory Scan

To scan through channels in the memory scan list, press the MEM key, then push the SCN key. If you are in a different scanning mode, you must stop the scan before switching to a MEMORY SCAN. In that case, press SCN|MEM|SCN. To add channels to the memory scan list, use the keys to tune in each of the channels you want to monitor. As you tune in each channel, depress MEM for three seconds to add it to the memory list. The MEM Annunciator will appear, letting you know the channel has been added to memory.
While in the MEM scan mode, touch the WX key to toggle the WX ALERT function off and on. The scan will stop when a channel picks up a signal. The scan will not continue until the input signal stops. To stop scanning, press the SCN key or the 16/9 key. Press in the PTT button exits the scan mode at the last channel display.
To start a Priority Scan Pressing the SCN key activates the PRIORITY SCAN mode. P SCAN will ap-
pear on the display. The priority channel is scanned every 2 seconds, even if another channel has a squelch break.
When a signal is received on the priority channel, the scan stops and the radio receives the priority transmission. WX ALERT can be toggled off and on by pressing the WX key. Screen When the unit is turned on the LCD light display is on and stays on. There is no contrast control. Weather (Wx) Dark clouds on the horizon? Press the WX key to enter the WX (WEATHER) MODE and get the latest weather information. The last used Wx channel always appears first. Use the keys to change the WX channel. In PRIORITY SCAN or MEMORY SCAN MODES, pressing the WX key allows the WX ALERT function to be toggled off and on. Select the WX channel before starting a PRIORITY SCAN or MEMORY SCAN.

If a WX ALERT a 1050Hz-tone burst transmitted from the NOAA Weather service is issued, a special circuit in the radio detects the tone and during scanning modes (except All Scan), a loud 2-tone warning will sound. The warning tone is canceled by pressing any key. The radio will stop scanning and switch to the WX channel to broadcast the warning. You know the radio is scanning the WX channel, if you see the WX ANNUNCIATOR flash as it scans through the weather channels.
