Chapter 2: Getting Started
2.1 Introduction
This chapter provides basic instructions to get you started using the DSM300
Digital Sounder Module with a Raymarine hsb
2 PLUS (Pathfinder) Series display.
Instructions for operating the DSM300 with a C Series or E Series display are
available in the handbooks for those products.
This chapter also describes Simulator mode and helps you to become familiar with
the basic functions of the display’s controls in Sonar operation mode. More
detailed information on using the controls and operating in Sonar mode is
provided in Chapter 4 and Chapter 5, 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 DSM300 places it in memory. If you power down the sounder less than one minute after
making a change, the setting is lost.
2.2 Powering on the Sounder Module
There is no power switch on the DSM300. The unit turns on when the power cord
is attached to boat’s power and plugged into the POWER connector on the
connector panel.
CAUTION:
The DSM300 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 DSM300 power cord at a point where it is easily
accessible.
Status LED
The LED on the front 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. For an explanation of the various error
codes, refer to the DSM300 Installation Manual.
