Lowrance lmf-400 ユーザーズマニュアル

3 

The design of the LMF-400 allows convenient mounting in the dash of 

your boat, or it can be mounted on any flat panel at least four inches in 

diameter. 
To mount the LMF-400 in the dash, first make sure there is sufficient 

clearance behind the panel in the desired location. At least 3-1/2 inches are 

needed behind the surface of the dash to clear all connectors and wiring. 
Recommended Tools and supplies 
Recommended tools for this job include: hole saw, 3/38" (86 mm) hole 

saw bit, drill, 1/8" (3 mm) drill bit (for starter hole). Required supplies 

for this job include: "U" bracket, lock washers and wing nuts (included). 
Installation Sequence 
You can install this gauge in some other order if you prefer, but we 

recommend the installation sequence listed below. 
1. Determine the location for the gauge so you can plan how and where 

to route the cables. This will help you make sure you have enough cable 

length for the desired configuration. 
2. Determine the location of the nearest device on the boat's NMEA 

2000 network, along with the route of the gauge's network cable. 
3. Determine the location for the alarm buzzer and its wire route. 
4. If you want the gauge's backlight to turn on when the dashboard 

lights are turned on, locate your boat's dash light switch and determine 

how to route the gauge's dash light wires to it. 
5. Install the gauge in a standard 3-3/8 inch (86 mm) hole in the dash. 

If no 3-3/8 hole available in the dash, you will have to drill a 1/8" pilot 

hole, then use a hole saw to cut a mounting hole. See instructions for 

Mounting the Unit below. 
6. Connect the buzzer wires and install the buzzer. If desired, connect 

the dash light wires to the boat's dash light switch. 
7. Connect the network cable to the NMEA 2000 network. 

If no standard mounting hole is available in the dash, drill a 1/8" pilot 

hole, then cut a 3-3/8 inch (86 mm) diameter mounting hole with a hole 

saw. A "U" bracket is supplied to hold the unit to the dash. Place it over 

the threaded studs on the back of the unit and secure it with the lock 

washers and nylon wing nuts provided with the unit.
