Chapter 4: System Setup
4.1 Introduction
Once you have installed your DSM250 and are familiar with its
basic operation (described in
Chapter 2 and Chapter 3 ), you need
to set it up so that it displays information according to your prefer-
ences.
This is achieved using the soft key controls that are displayed
when you press the
MENU
key.
In most cases, you will only need to use the
MENU
key options
when you first set up your system. As you become more familiar
with your system, you may decide to customize some aspects,
such as the screen and help setting.
Note: All settings described in this chapter are retained when the unit
is powered off. However, there is a one-minute delay from the time
you make the setting change to when the DSM250 places it in memo-
ry. If you power down the sounder less than one minute after making
a change, the setting is lost.
This chapter covers the following topics:
• Changing the default set up parameters
• Sounder specific parameter functions and default settings
You should check the functions of the parameters and decide on
the new settings before making the changes.
4.2 Changing the Set Up Parameters
The set up parameters are divided into two sections:
• System , to control the aspects of the system that are not specific to
the sounder module.
• Sonar, to control the Sonar-mode display preferences, including
HSB mode, calibration, and simulator.
This section provides instructions for displaying and changing the
default values. The following sections list the parameters and
their possible settings and describe the function of each parameter
in turn.
