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- ers from the Lowrance web site, www.lowrance.com. part number, 988-0147-582, at www.lowrance.com.

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.
