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.
We have designed this book so you don’t have to read the whole thing
from front to back to find the information you want. At the start of each
segment, we’ll tell you what content is coming up next. If it’s a concept
you're already familiar with, we’ll show you where to find the next im-
portant topic.
We lead off the manual with proper Distress Call procedures on page 4.
We put it at the front of the book to make it easy to find in case of an
emergency.
The first section covers LVR-850 installation and specifications.
The second section, Basic Radio Operation, goes over some basic func-
tions of the radio and includes instructions on how to set up your MMSI
(Maritime Mobile Service Identity) number. You can't make a call
without it! To jump to MMSI setup, flip to page 8. To acquire a
free MMSI number, see the web address on the bottom of page
ii.
The third section, Advanced Radio Operation, offers more detailed in-
formation about the radio's features. The section will touch on all as-
pects of the radio's functionality, providing clear and complete explana-
tions via a convenient alphabetical layout.
Let’s get started!
Powering Your Radio
(Power Supply cable – red and black wires)
The unit works from a 12-volt electrical system. You may attach the
radio to a 12-volt battery or to an auxiliary power panel.
If possible, keep the power cable away from other boat wiring, especially
the engine's wires. This will provide the best isolation from electrical
noise. The power cable has two wires, red and black. Red is the positive
lead, black is negative or ground. Make sure to attach the in-line fuse
holder to the red lead as close to the power source as possible.
Auxiliary Wires
The white and black auxiliary wires on the back of the unit connect
your radio to an external speaker. Connect the white (+) wire to the
speaker's positive lead, and connect the black (–) wire to the speaker's
negative lead.
