Introduction | Lowrance electronic LMF-400 manual

Section 1: Introduction

Thank you for buying the Lowrance LMF-400! Your unit is a high- quality, multi-function, digital gauge designed to work with a LowranceNET network. This is the NMEA 2000 networking system developed by Lowrance Electronics.

Caution:

Installing LowranceNET NMEA 2000 devices is significantly different from installing earlier Lowrance components without NMEA 2000 features. You should read all of the installation instructions before proceeding.

This gauge will only work with a NMEA 2000 network. It MUST be connected to a NMEA 2000 network or it WILL NOT function. When properly installed, the LMF-400 will display information from a variety of Lowrance Electronic Probe (EP) sensors connected to the network.

A NMEA 2000 network using LowranceNET components.

All Lowrance NMEA 2000 capable devices are either NMEA 2000 certified or certification is pending. See our web site, www.lowrance.com, for the latest product status information.

To get started with your Lowrance gauge, first read the installation section. It contains instructions for installing the LMF-400.

After you've read those instructions, install the gauge and any EP sensors you may have purchased, then read the rest of this manual. Each sensor comes with its own installation instruction sheet, but this manual describes how the gauge operates with each sensor, and how to calibrate the sensors. The more you know about the gauge, the better it will work for you.

Your package also includes another manual, part 988-0154-172, which contains complete instructions for creating or expanding a NMEA 2000 network.
