Setup > Fuel (Explorer 438 Only) - NorthStar EXPLORER 435 Installation And Operation Manual

Palette
Use this to select a color palette. Each color
within the palette represents a different echo
strength, as shown on the sonar displays.
There is a choice of five color palettes: Black, Blue,
White, Vivid and 8 color. The first four display
more detail, whilst the 8 color palette shows a
greater distinction of signal strength between
each adjacent color. For the 16 color palette, each
color covers 1.5 dB signal range. For the 8 color
palette, each color covers 3 dB signal range.
Color bar
This shows the range of colors used for the
selected color palette.
It can be switched On or Off. If switched On, it is
displayed down the left hand side of all the sonar
displays.
Digit size
Use this to change the size of the depth display
on the sonar displays. There is a choice of:
Small, Medium and Large.
Bottom lock
If Bottom lock is On, the zoom section moves
so the bottom is always displayed in the zoom
section, regardless of changes in depth.
If Bottom lock is Off, the bottom will not be
displayed in the zoom section when it is outside
the range covered by the zoom bar.
Using the Bottom Lock and the A-Scope features
together can be a powerful aid in recognising the
type of bottom.
Fish symbols
These appear only in the main sonar displays. Fish
symbols can be shown in three ways:
