Chapter 3: Getting Started
3.1 Introduction
This chapter provides basic instructions to get you started using
the DSM250 Digital Sounder Module. It describes automatically
updating the display unit’s software to be compatible with the
DSM250, if necessary. It also describes Simulator mode and can
help you to become familiar with the basic functions of the dis-
play’s controls in Sonar operation mode. More detailed informa-
tion on using the controls and operating in Sonar mode is
provided in
Chapter 5 and Chapter 6 , respectively.
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.
3.2 Powering on 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.
WARNING:
The DSM250 should be located so that the power cord can be
easily removed, 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 front panel blinks green when the module is pow-
ered 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.
