EQ44/54 Introduction and safety summary Chapter 1-1
1.1 Introduction and system familiarization
Congratulations on your purchase of SIMRAD EQ44/54 Echosounder and
Fishfinder - a high performance echosounder in a unique slim-line design
with a bright 10” ATFT/TFT (EQ44) or 15” TFT (EQ54) color display.
The EQ44/54 is both an echosounder system with selectable frequency i.e. 38,
50 or 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.
The SimNet data and control network provides high speed data transfer and
control between Simrad products that are integrated as a total navigation,
steering and communication system on board.
How to use this manual?
This manual is written for the products: EQ44 and EQ54, which 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. 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.
1,3
Indicates that you should press the keys [1] and [3] to obtain what is
written in italic next to the key.

Chapter 1-2 EQ44/54 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.
The lifetime of the internal battery is minimum 5 years. If not exchanged
before it goes flat, all data in the unit’s memory will be lost. We strongly
recommend that you have the battery exchanged at your local Simrad work-
shop max. 5 years from date of purchase.
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 11.10 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 EQXX.
Quality service personnel: The EQXX is sealed and does not contain any
user serviceable parts. Opening of the unit will void its warranty. Touch-
ing electrical parts inside may cause bodily harm. If the unit is not working
properly, check sections 11.7 Preventive maintenance, 11.8 Repair and service,
and 11.9 Troubleshooting. If your EQXX requires servicing or repair, call your
authorized SIMRAD dealer.
Cleaning:
Do not use any kind of strong solvents e.g. spirit, alcohol, gasoline or oils.
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 - Glos-
sary 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.
Software: The software version of the EQXX (see start-up display) should
always be informed in a service situation.

EQ44/54 Fundamentals & initial start-up Chapter 2-1
2.1 Fundamentals of the display and page system
The EQ44/54 Echosounder has a multi-function screen and data
presentation system with full screen and different types of split
screens. The series of pages under the function keys (situated in the
left column of the keypad) will in most situations be sufficient infor-
mation for the operator.
In split screens consisting of up to four displays, the active display
is indicated by a solid red frame. Use the [WIN] key to clockwise
toggle between which display on the screen is active. Only active
displays are operable.
The [PAGE] key differs from the other function keys. There are four
pages under the [PAGE] key which can be set up to the presentation
you prefer by exchanging an existing display in the PAGE system
with a new one selected from a function key or via the menu - see
next page. Single press on the [PAGE] key will toggle between the
active pages under the function keys e.g.:

Chapter 2-2 EQ44/54 Fundamentals & initial start-up
Long press on the [PAGE] key will start
a rotation of the four pages in intervals of
5 seconds (increase/decrease the time in
[MENU], [7], [2]). Press any key to stop
rotation.
2.1.1 Example of how to exchange a page in the PAGE system
The four pages in the PAGE system are collected from the STND,
B-LCK, ZOOM and SHIFT menus in the sequence of which the
function keys appear on the keypad ie. the first page is from the
STND function, the second page is from the B-LCK function, the
third page is from the ZOOM function, and the fourth page is from
the SHIFT function. This sequence can not be changed, only the
choice of display collected from each function can be changed e.g.:
PAGE
Press the [PAGE] key until the full screen standard display appears
MENU
Call up the menu bar, and...
1,3
collect the Dual frequency display
- or you can toggle between the available displays in the STND func-
tion by pressing (long press) the [STND] key repeatedly.
The same applies for the other three pages in the PAGE system ie.
press the [PAGE] key until a display from the B-LCK, ZOOM or
SHIFT function appears and then collect a new display from the
appropriate menu.
The display sequence under the function keys is the same as the
display sequence in the matching menu.
2.1.2 Example of how to select a new display in a custom screen
In custom screens with multiple window combinations, all dis-
plays, which are not main function displays, are exchangeable. It is
also possible to change the right half of the screen from half screen
window to two quarter windows and vice versa. Example:
MENU
Call up the menu bar, and...

EQ44/54 Fundamentals & initial start-up Chapter 2-3
Highlight a function e.g. Depth & temperature diagram in the MISC
menu.
WIN
Press [WIN] several times to check the screen image (situated to the
far right in the top line of the menu bar) which windows the function
can be placed into
ENT
Press [ENT] to enter the highlighted function into the highlighted
window
If the function text in the menu is red, the display will not be avail-
able for the selected window.
2.2 Key functions
Some of the key functions are general and can be applied at any
time, other key functions are related to a certain menu(s) and can
only be applied when in the appropriate menu.
EVENT
Inserts a vertical mark at current ping and sends out WPL via NMEA
to connected chartplotter.
MENU
Turns the menu bar on/off. Exits any data display without taking any
action.
ENT

down) in echo display.
+/-
Changes echosounder range i.e. + (plus) for larger range and -
(minus) for smaller range. Toggles between available values.
