Lowrance electronic LMF-400 manual Preparation, Mounting the Unit

Section 2: Installation

Preparation

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. Also, see that there is adequate room to connect power and transducer cables. 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, drill, drill bit (for

starter hole). Required supplies for this job include: "U" bracket, lock washers and wing nuts (included).

Mounting the Unit

Cut a 3-3/8 inch diameter mounting hole with a hole saw. A "U" bracket is supplied to hold the sonar 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.

Secure unit to the dash using "U" bracket as shown.

The bracket is designed to secure the unit to a dash with a thickness of 2 mm. If your dash is thicker than 2 mm, the "U" bracket will be too long. Simply place washers or spacers between the unit and the bracket until you can tighten the wing nuts and secure the unit in place. Once the unit is in place, you need to connect it to a power supply, to the speaker (provided) and the LowranceNET.
