LST-3800
In-Dash Digital Sonar Gauge
Installation & Operation Instructions
The LST-3800 is a depth and temperature gauge that comes with a 200 kHz transducer, features deep and shallow alarms and has three main page displays. It can show depth in Meters or Feet, temperature in Fahr- enheit or Celsius and its display may be set to rotate between Tempera- ture, Depth or Dual display pages. The unit fits in a standard 2-1/8" (54 mm) hole used by most marine equipment manufacturers.
The 3800 is designed to display water depth and surface water tempera- ture, but you MUST have a transducer with built-in temp sensor to re- ceive temperature information.

Mounting Preparations
When installed, the gauge's bezel will cover a circular area at least 2-1/2" (64 mm) wide on the front of the dash. To mount the unit, make sure there is at least 4-1/8" (105 mm) from the front of the dash to any ob- struction behind the dash. The maximum usable dash thickness is 1-1/8" (28.5 mm). Also, make certain there is room to route the unit's cables. The following figure shows gauge dimensions.
