Lowrance lmf-400 用户手册

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. You 

are now ready to wire the unit to the buzzer (piezo) and dash lights.  
 

 

Connecting the LMF-400 to the buzzer (piezo), will enable the buzzer to 

sound when buttons are pressed and when alarms and level warnings 

are triggered. Wiring the unit to the boat's dash lights, will turn on the 

LMF-400 backlight when the dash lights are turned on.
