Chapter 3: Getting Started
3.1 Introduction
This chapter provides information to get you started using your HD Series
Fishfinder system. It will help you to become familiar with the basic functions
of the display’s controls and learn how to operate the sonar system using
Simulator mode. More detailed information on operating the display unit is
provided in
Chapter 5 ; Sonar functions are described in Chapter 6 .
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.
3.2 Switching the Units On and Off
Powering the Sounder Module
There is no power switch on the DSM250. The unit turns on when the power
cord is attached to ship’s power and plugged into the
POWER
connector on the
connector panel.
Note: The DSM250 should be located so that the power cord can be easily re-
moved, if necessary. If the sounder is placed in a difficult-to-reach location,
Raymarine strongly suggests installing a power switch on the DSM250 power
cord at a point where it is easily accessible.
Status LED
The LED on the connector panel blinks green when the module is powered on
and operating normally. If the unit detects a problem, the LED blinks amber to
indicate a warning or red for an error. The number of times the LED blinks is a
code representing the nature of the problem. See
Status LED on page 7-6 for
more details.
Powering the Display Unit
The factory default power-up mode is full-screen Sonar mode. Once you have
used the display unit it powers-up in the last used mode. The following
sections describe the power-up sequence and how to select simulator mode.
➤
To switch the display on in Sonar mode:
Press and hold the POWER key until the unit beeps. The keys light up and after
a few moments the display shows the fishfinder screen.
