1.1 Introduction and system familiarization
Congratulations on your purchase of SIMRAD EQ42/50/52 MKII
Echosounder and Fishfinder. Great care has been taken to create this
innovative video sounder … both in design and performance.
The EQ42/50/52 MKII is a unique new slim-line product in the Simrad
Marine Line, and is available with a 10” ATFT (EQ42), 14” TFT
(EQ50), or 15” TFT (EQ52) large LCD display in color.
The echosounder system with selectable frequencies will provide an
impression of Bottom expansion, VRM expansion, A-scope and White
line.
DS42/50/52 Dual Station for the EQ42/50/52 is available in 10” ATFT
color, 14” or 15” TFT color.
How to use this manual? The manual is written for the products:
EQ42, EQ50 and EQ52, which all share the same type of software.
From hereon, these models are referred to as: EQXX.
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.
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 keys.

1.2 Safety summary
Precaution The operating unit should not be exposed to direct sunlight,
as “boiling”the display may cause too high temperatures internally and
subsequently damage parts of the unit beyond repair.
Quality service personnel The EQXX 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 or death. If the
unit is not working properly, check sections 9.8 Preventive maintenance,
9.9 Repair and service, and 9.10 Troubleshooting. If your EQXX requires
servicing or repair, call your authorized SIMRAD dealer.
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 9.11
Specifications). Ensure that the power cord is firmly attached.
Grounding The EQXX is a sophisticated piece of electronic equip-
ment. To reduce electrical interference and risk of electrical shock,
properly ground the unit to the ship’s ground using the ground screw on
the back of the unit.
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 EQXX can be erased
by making a reset of the unit and thus return to factory default settings.
Principles of operation The scientific principles of operation of the
EQXX are explained in chapter 8. Principles of operation.

2.1 Fundamentals of the PAGE and WINdow system
The EQXX Echosounder has a multi-function screen data presentation
system. You can choose to have a full screen, or a screen divided into
e.g. an echo display and two data/echo displays, etc.
The display which is currently activated is indicated by a highlighted
frame around the active window. There are five screen combinations to
choose from:
12
WINdow 0
43
56
1. Full (1/1) screen. 2. Four ¼ displays. 3. Two ½ displays.
12
4
65
3
4. & 5. Combination displays of one ½ and two ¼ displays.
)WINdows 5 and 6 are dedicated for echo displays and related setup.

EQ42/50/52 Fundamentals & initial start-up Chapter 2

As many as 4 screen combinations or full
screens can be saved in four pages.
Press the [PAGE] key to toggle between the
four pages, or hold the [PAGE] key depressed
to start a rotation of the four pages.
Press [PAGE] again to return to manual
operation.
To mix and match the various echo and data displays you wish to have
in the PAGE and WINdows pesentation, you will first need to know
what is pre-set from the factory:
PAGE Scroll through the four pre-set pages to see if you wish to exchange
any of the displays with a different one.
Example of how to edit a pre-set page:
window
2
window
5window
3
We pretend that in this page, window 2 contains the
navigation display (highway), window 3 an echo
display in 50kHz, and window 5 an echo display in
200kHz.
You now wish to insert the “Echosounder setup”display in window 3
instead of the echo display in 50kHz. This is the procedure:
WIN Press the [WIN] key until the frame around window 3 is highlighted
MENU Call up the menu bar, and…
3,8 then call up the ECHO menu and select “Echosounder setup”
- you will now have the “Echosounder setup”display in window 3
instead of the echo display in 50kHz.
Example of how to edit a full screen to four ¼ displays:
We pretend that you are looking at a full screen which you wish to
divide into four ¼displays. This is the procedure:
MENU First call up the menu bar, and…
1then call up the POS menu - see example next page.

POSITION
WIN

POS
_1_Position
What you do now will determine
which WINdow the display you are
about to select will appear in.
Press the [WIN] key repeatedly to
scroll through the window system.
WIN Press the [WIN] key once to select window 1
-which is the left top quarter of the screen.
1Select the Position display
- you will now have the position display presented in window 1.
The rest of the windows in this page i.e. window 2, 3 and 4 will contain
the displays which were pre-set from the factory. They can all be
exchanged with new displays at your choice.
)However, the same display can not appear twice on the same page,
so in case you are trying to select the same display in a second
window, this is what will happen:
As per above example, you have selected the Position display in
window 1, but it may just happen that the Position display was pre-set
to window 2 –therefore window 2 will now show the legend: “Select
display via MENU.”
You may select the same display to appear on different pages, but not
on the same page.
