EQ33 Introduction and safety summary Chapter 1-1
1.1 Introduction and system familiarization
Congratulations on your purchase of SIMRAD EQ33 Echosounder and
Fishfinder - a high performance echosounder in a unique slim-line design
with a bright 6” TFT color or monochrome display.
The EQ33 is both an echosounder system with selectable frequency i.e. 50
and 200 kHz, providing an impression of what is to be found in the water
under the vessel, and it is a repeater for navigational data from connected GPS
receiver.
DS33 Dual Station for the EQ33 is available with a 6” bright TFT color
or monochrome display. The main unit and the dual station are identical in
design and operation.
How to use this manual?
It is a good idea if you make yourself familiar with the key functions, menu
structure and rotation of pages (screens) described in chapter 2 before you
start out, and then proceed with section 2.5 Initial start-up. For quick location
of a certain term, please check the “Glossary of terms” and the “Index” at the
back of the manual. Also, “How to get started” further on in this chapter will
give you a quick introduction to some of the features you have access to in
your new echosounder.
The display examples shown in this manual are not always an exact copy of
what you will see on the screen, as the presentation depends on your system
configuration and choices of setup.
How to interpret special marked key symbols etc. in the manual:
+/-
Either the + (plus) or - (minus) key may be applied.
0-9
Alpha-numeric keys for insertion of figures.
A-Z
Alpha-numeric keys for insertion of letters.
) Emphasizes important points.
3,7
Indicates that you should press the keys [3] and [7] to obtain what is
written in italic next to the key.
Chapter 1-2 EQ3 3 Introduction and safety summary
1.2 Safety summary
Precaution: Do not open the equipment, only qualified persons should work
inside the equipment. If the glass in the screen breaks, be careful not to get cut
on the sharp edges of the glass pieces.
Power source, fuse and power cable: Check that the DC power supplied to
the unit is within the range of 10 to 32 volts. Note that the appropriate fuse
must be employed (see the fuse rating in section 9.10 Specifications). Ensure
that the power cord is firmly attached.
Grounding: To reduce electrical interference and risk of electrical shock,
properly ground the unit to the ship’s ground using the ground screw at the
rear of the unit. Good grounding should also be exercised for any equipment
connected to the EQ33.
Quality service personnel: The EQ33 is sealed and does not contain any user
serviceable parts. Opening of the unit will void its warranty. Touching electrical parts inside may cause bodily harm. If the unit is not working properly,
check sections 9.7 Preventive maintenance, 9.8 Repair and service, and 9.9
Troubleshooting. If your EQ33 requires servicing or repair, call your authorized SIMRAD dealer.
Glossary of terms: If you have never used an echosounder before or if you are
unsure of how a term is used in this manual, then turn to Appendix A - Glossary of terms.
Default settings: All user implemented data in the EQ33 can be erased by
making a reset of the unit and thus return to factory default settings.

EQ33 Echosounder operation Chapter 5-1
5. Echosounder operation
The echosounder function of the EQ33 determines the distance
between its transducer and underwater objects such as fish, lake
bottom or sea bed. It does this by utilizing the fact that an ultrasonic
wave transmitted through water travels at a nearly constant speed
of 1500 meters (4800 feet) per second. When a sound wave strikes
an underwater object such as fish or sea bottom, part of the sound
wave is reflected back toward the source. Thus by calculating the
time difference between the transmission of a sound wave and the
reception of the reflected sound wave, the depth to the object can be
determined.
The entire process begins in the display unit. Transmitter power is
sent to the transducer as a short pulse of electrical energy. The electrical signal produced by the transmitter is converted into an ultrasonic signal by the transducer and transmitted into the water. Any
reflected signals from intervening objects (such as a fish school)
are received by the transducer and converted back into an electrical signal. It is then amplified in the amplifier section, and finally,
displayed on the screen.
The picture displayed is made up of a series of vertical scan lines
(pings), one for each transmission. Each line represents a ‘snapshot’
of what has occurred beneath the boat. The series of snapshots are
accumulated side by side across the screen, and the resulting contours of the bottom and fish between the bottom and surface are
displayed.
Selecting echosounder displays
The EQ33 provides various types of echosounder displays: standard
echogram, A-scope, bottom expansion (zoom) and VRM expansion. Each display has its special advantages. Select the appropriate
setup for the echosounder display in the presentation “Setup” and
“Echosounder setup” displays, considering current sea area and
target fish.
