iv FCC Radio Frequency Compliance Requirements and Warnings When operating your marine radio transceiver, you should know that the antenna radiates radio frequency (RF) energy. This radio was de- signed to meet the FCC’s rules and regulations for the maximum per- missible exposure to radio frequency energy.
1 Section 1: Installation Introduction Thank you for purchasing the Lowrance LVR 850 DSC VHF Radio. We know you’re anxious to try it out, but first, let us explain how this manual can help you get the most out of your new radio.
2 The remaining auxiliary wires are used for DSC (Digital Selective Calling) service, where the radio can exchange latitude and longitude position information with a GPS (Global Positioning System) receiver in NMEA 0183 format. Wiring to transmit NMEA information to a GPS receiver.
3 Install the gimbal bracket, which looks similar to the one pictured here. Place the bracket so the arms slope toward the radio's front. Once a location is determined, use the bracket as a template and mark the mounting holes. Screw the bracket to the mounting surface.
4 sure your antenna and its installation complies with all local and fed- eral regulations. Never operate your radio unless it is connected to the antenna. The antenna must not exceed an antenna gain of 3 decibels (dB). The antenna cable requires a PL259 connector, and the cable connects at the back of the radio.
5 Section 2: Basic Radio Operation This section addresses the radio’s 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.
6 Power/Volume The volume knob at the top right of the radio’s face is used to power up the LVR 850. Turn the knob clockwise to turn on the radio. The unit will start on Ch.
7 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 in- coming call, place a call to all ships or to one of up to 10 stored MMSI numbers from a saved directory.
8 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.
9 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.
10 NOTE You need only to modify the big (MMSI) digits. The small digits (character field position of the MMSI digit) will be generated auto- matically. 2. Use the ↑ ↓ keys to enter the first digit of your MMSI number, then press the MEM key to advance to the second digit.
11 call key again and the call is placed again. You can exit the call func- tion 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. For more in depth information on placing calls see page 13.
12 the calling vessel’s 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.
13 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 de- scription of how to place a non-DSC call.
14 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 ALL- SHIPS .
15 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.
16 When an ACK is received, the distress mode is automatically can- celed 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.
17 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.
18 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 num- ber) over.
19 Individual Call Reception of an individual DSC call sets up communication on the working channel requested by the caller. Your radio automatically transmits an ACK (Acknowledgement) message back to the calling ra- dio. If the caller's MMSI matches an entry in your directory, its location will be displayed.
20 Directory The Directory is an organized list of (up to 10) MMSI numbers stored on the DSC calling directory. Storing/Editing MMSI Data To store a new MMSI in an unused location, follow these steps: 1. Press the CALL key to display LAST . Use the ↑ ↓ keys to select DIR .
21 The example shows the MMSI Data 987776510 being entered. To change or edit MMSI data, select a FL location and press the MEM key to change the data.
22 NOTE DSC calls will NOT be received when the radio is receiving or sending out a transmission. During scanning, Ch. 70 is monitored on an allocated time-slot basis and DSC calls will be received. GPS Operation Your radio is NMEA 0183 compatible, which means it can work with a GPS unit.
23 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.
24 3. Press the Call key and the big digit will blink and the channel will switch to Ch. 16. Press the CALL key again and the position data will be sent through Ch. 70. After the transmission on Ch. 70, the ID Annun- ciator will flash, indicating it is waiting for an ACK .
25 To receive a position request: 1. The alarm will sound and P1 will be displayed on the screen in big digits. The MMSI directory location will be shown next to it, in small digits.
26 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.
27 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. W X ALERT can be toggled off and on by pressing the WX key .
