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.

Recommended Tools and Supplies  
Supplies are not included, unless otherwise indicated. If the dash does  
not have a standard 2-1/8" (54 mm) hole, you will need a drill or saw to  
make the hole. Carefully measure the dash thickness and the hole area  
before cutting or drilling. The buzzer installation requires two cable ties.  
If you need to extend any of the wires, use a minimum of 24-gauge wire  
and wire connectors of your choice. Wire nuts or electrical tape are re-  
quired to cap any unused bare wires.  
When you determine the location for the LST-3800, drill a 2-1/8" (54 mm)  
hole in the dash or use an existing gauge hole. Slide the cables through  
the hole from the front side of the dash, then push the LST-3800 housing  
through the hole until it is flush with the dash surface. Make sure the  
gauge is aligned correctly. Next, slide the rubber gasket and plastic-  
mounting collar over the cables and onto the back side of the gauge.  
Insert gauge through the hole in the front side of the dash (left). Slide  
the rubber gasket over the cables, followed by the plastic collar (right).  
Slide the gasket forward so it is flush with the back of the dash, then  
screw on the mounting collar, turning it until it fits snugly against the  
gasket and the back of the dash.  
Find a buzzer location that is protected from the elements, but still will  
allow you to hear the buzzer. We recommend connecting the buzzer  
wires, then using two cable ties to attach the buzzer to one or both of the  
cables at the back of the gauge.  
Finish the installation by connecting the cables as described in the fol-  
lowing wiring diagrams and photos.  
Wiring  
The LST-3800 operates from 10 to 15 volts DC (12-volt system). It must  
be wired to a 1-amp fuse. Failure to use a fuse with this product  
WILL VOID the warranty and could result in damage to the unit  
or your boat.

In the configuration above, the unit is always on. It will draw 11 milli-  
amps of current with the backlight off and 40 milliamps with the back-  
light on full brightness. Typically, the maximum recommended current  
load on a boat in storage is about 50 milliamps. A battery will self dis-  
charge at a rate of about 9 milliamps. A battery's normal discharge plus  
the gauge current (lights off) amounts to approximately 20 milliamps,  
well below the recommended load limit in storage.  
To automatically have the gauge backlights turn on when you turn on the  
other dashboard lights, connect the red dash light wire to the switch con-  
trolling the dash lights.  
If you want to turn off the gauge when your not using it, connect the red  
wire from the power/transducer cable to your boat's accessory switch, or  
install an optional switch between the unit and the power source. See the  
following figure.

Caution:  
The bare ends on any unused wires could cause an electrical short  
if left exposed. To prevent this, you should cover the individual  
wire ends — either by capping them with wire nuts or wrapping  
them with electrical tape. You should cut off the bare wire before  
taping off the ends.  
After connecting the power wires to the battery or switch, connect the  
power/transducer cable to the gauge's power cable (above).  
The unit won't be harmed if the power wires are connected backwards,  
but it won't work until they are connected correctly.  
NOTE  
The LST-3800 comes with a 200 kHz transducer. For installation in-  
structions, download Installation Instructions for Skimmer Transduc-  
Operation  
The displays and settings in this digital gauge are controlled by a three-  
button keypad. The buttons are MENU, UP and DOWN. The MENU key  
takes you to the gauge's main menu, allows you to access other internal  
menus and is used to modify menu options. The UP and DOWN buttons  
allow you to scroll through all menus.

Timeout  
There is no exit key in the LST 3800. The menus "time out" instead. That  
means they automatically close after a preset amount of time. When you  
install the gauge, the default timeout duration is 5 seconds. You can  
modify the TIMEOUT setting by pressing MENU and using the up and down  
keys to scroll through the main menu. When TIMEOUT appears in the cen-  
ter square — like the illustration below — press MENU. That will open  
the Timeout Menu, which has four settings: 3, 5, 7 and 10 seconds. Use  
the UP and DOWN keys to choose a setting, then press MENU.
