Chapter 5: Adjusting the Display
5.1 Introduction
This chapter provides instructions for using the HD Series Fishfinder display
units. It will help you to become familiar with the display and the functions of
the controls before you start using the unit. Detailed information on Sonar
operations is provided in
Chapter 6 . Chartplotter operating details are given in
Chapter 7 and Chapter 8 .
Note: All settings described in this chapter are retained when the unit is pow-
ered off. However, there is a one-minute delay from the time you make the set-
ting change to when the DSM250 places it in memory. If you power down the
sounder less than one minute after making a change, the setting is lost.
Simulator
The the HD Series Fishfinder system includes a simulator function that
enables you to practice operating your Fishfinder or Chartplotter (Raychart
models only) without data from the transducer or GPS system. See for
Section 3.4 for information on using simulator mode.
Changing the Brightness & Color Settings
The
MULTI
key on the LCD Fishfinder provides controls to set up the display
colors and brightness. You can choose the background color and the color
threshold. Color threshold lets you determine which echoes are displayed, by
selecting the minimum color strength the fishfinder uses. You can also select
the color set, for a bold or soft color palette. The brightness of the screen can be
adjusted over a wide range, suitable for viewing in daylight (high brightness
level) or at night (low brightness level).
The key lighting is automatically adjusted as you alter the screen lighting, so
that you can always find the keys. If you set the backlight to a high level, the
key lighting is dimmed; if you set the backlight to a low level, the key lighting
level is increased.
