SET AND ADJUST FEATURES

After power-up, features can be adjusted using the following procedure:
1. Press the MENU button to display feature adjustments.
2. Press the LEFT or RIGHT button to find the feature you want to adjust.
3. Press the UP or DOWN button to adjust the feature (see specific instructions below for Range
and Depth Alarm).
4. Press the MENU button to restore the normal display.
Tip: When no menu is displayed, press and hold the
CONTRAST - Contrast is the darkness or lightness of the display. Both your viewing angle and the
ambient temperature affect the contrast.
CAUTION: Facing the screen toward the sun for extended periods may cause the display to reach its
upper temperature limit and become black. If this occurs and you cannot adjust it lighter, immediately
cover the screen or turn it away from the sun.
LIGHT - The Fishin' Buddy 4200™ has a display backlight for use when there is not enough
daylight to view the screen. The backlight also generates heat and can be used to help warm the
display in cold weather.
GAIN - The gain control sets the graph's overall sensitivity to echoes. Generally, a higher gain
number means that more fish and structure are shown. Lowering the gain may help reduce
interference caused by trolling motors and other sources of noise.
TIP: Use as much gain or as little gain as you want, but remember that the bottom depth readout may
not work under all settings.

SCC - The Surface Clutter Control reduces undesirable signals on the graph. Such signals may
include surface clutter (created by turbulence around the transducer), thermocline, air bubbles,
algae bloom, etc. Turn on SCC if these signals inhibit the display of the bottom.
NOTE: Turning on the surface clutter control may inhibit shallow-water bottom readings.
ICE MODE - The ice fishing mode control overrides the screen clutter control and increases the
gain significantly to help display smaller objects. Although this improves the picture in most ice
fishing situations, it may increase clutter and is normally turned off for other types of fishing.
RANGE - The bottom range control allows you to set how deep the bottom graph will display. The
bottom range is displayed in the upper-right and lower-right corners of the graph.
In automatic mode, the Fishin' Buddy 4200™ sets the graph range to graph from the water surface
down to just below the bottom.
AUTO
- This symbol in the upper-right corner of the display indicates automatic range mode.
You may want to set the range manually if the bottom reading becomes unreliable or if you are
only interested in seeing the top portion of the water. In this case, the AUTO symbol will disappear
indicating that you set the range yourself.
In bottom-tracking mode, the Fishin' Buddy 4200™ sets the range to graph the 10 ft (3 m) of water
just above the bottom. This zoomed-in graph is useful for determining bottom features and for
marking fish lying close to the bottom.
