Installation:

CAUTION: Disconnect the battery during
installation. Tighten nuts on the
backclamp only slightly more than you
can tighten with your fingers. Six inch-
pounds of torque are sufficient. Over­tightening could result in damage to the
instrument and may void your warranty.

Mounting

1. Cut a 3-3/8” diameter hole in the dash
and mount the gauge with the backclamp
supplied.

The butt connectors have a heat activated
waterproofing. Once the butt connections
have been crimped, slowly apply heat with
a heat gun until you see sealant coming
out of the connector ends. It is
recommended to wrap the connections
together with electrical tape for further
protection.

Operation

Speedometer

The speedometer is a digital instrument
with the appearance of an analog
instrument. The speedometer is designed
to be operated from a “paddle wheel”
sensor. A microprocessor controlled
stepper motor moves the pointer to display
boat speed using a linear dial.

The microprocessor and stepper motor
provide excellent accuracy. Variations in
the operation of the “paddle wheel” sensor
are however fairly common. These
variations may be caused by the mounting
location of the “paddle wheel” on the hull,
which affects water flow characteristics, or
turbulence and air bubbles in the area of
the “paddle wheel”. Therefore, calibration
of the speedometer may be required and is
easily accomplished by using the Trip Log
display or the pointer.

display.
button causes the display to change to the
“settings” sub menus (see Figure 2, page 6).

When the settings menus have been
selected, pressing the “Mode” button for a
short period of time causes the display to
cycle through the setting options. Within
each setting selection, pressing the
“Down” and “Up” buttons causes the
affected setting to change. The
microprocessor will automatically record
the new settings as you adjust them.

Trip Log

The Trip Log is similar to the trip
odometer in an automobile. The distance
traveled, as recorded by the speedometer
“paddle wheel”, is displayed.

The Trip Log may be reset to zero, the
units of measure changed, or the
