Note!
Insert or remove C-MAP cartridges ONLY through CHART menu or when unit is off.
All electronic navigation equipment is subject to external factors beyond the control of the
manufacturer.Therefore such equipment must be regarded as an aid to navigation.The
prudent navigator will, for that reason, never rely on a single source for position fixing and
navigation.

CA42/50/52 Introduction and safety summary Chapter 1

1.1 Introduction and system familiarization
Congratulations on your purchase of SIMRAD CA42/50/52 DGPS
ChartRadar with Echosounder - a combination of the latest GPS
receiver technology with built-in differential receiver for accurate
positioning and prepared for SDGPS, plus: detailed cartography and
high performance radar and echosounder technology; all in a unique
slim-line design with a 10” ATFT (CA42), 14” TFT (CA50), or 15”
TFT (CA52) large LCD display in color.
The CA42/50/52 chart system includes a built-in world chart for
rough planning and overview. The choice of chart system best suitable
for the CA42/50/52 was carefully singled out to be the C-MAP NT+
mini cards. The optional C-MAP cards are available world-wide at
your local Simrad dealer.
The echosounder system with selectable frequencies will provide an
impression of Bottom expansion, VRM expansion, A-scope and white
line.
The radar system with dual EBL and VRM markers, direct Quick-
range keys, off-center mode, etc. together with Dual radar feature …
two radar displays in one screen, one for short range and one for long
distance observations.
The Global Positioning System is at this time and age the most
common system used for navigation and positioning all over the world.
Not only for maritime use, but also for land-based applications and
aviation. The satellite-based system has been developed and is operated
by the US Department of Defense in order to provide an accurate and
reliable service, which include a 24-hour global coverage. The GPS
system consists of approx. 24 satellites which orbit around the Earth at
an altitude of approx. 20,200 km. The satellites transmit perfectly
synchronized data. However, depending on the position, the signals will
reach the receiver at a slightly different time. By adding the measured
time difference to the known position of the satellites it is possible to
calculate the ship’s position to within a few meters.

CA42/50/52 Introduction and safety summary Chapter 1
6
DS42/50/52 Dual Station for the CA42/50/52 is available in 10”ATFT
color, 14”TFT color and 15”TFT color.
How to use this manual? The manual is written for the products:
CA42, CA50 and CA52, which all share the same type of software.
From hereon, these models are referred to as: CAXX.
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 2.7 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.
1,3 Indicates that you should press the keys [1] and [3] 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.
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 (F6.3A). 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 on the back of the unit. Good grounding should also be exercised
for connected equipment, refer to separate Installation manual.

2.1 Fundamentals of the PAGE and WINdow system
The CAXX DGPS ChartRadar with Echosounder has a multi-function
screen data presentation system. You can choose to have a full screen,
or a screen divided into e.g. a chart display and two data/chart displays,
etc.
The current active display 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 shown
together in the same screen.
)Not all displays are available in any size windows.

CA42/50/52 Fundamentals & initial start-up Chapter 2
8
As many as 4 screen combinations or full
screens can be saved in 4 pages (layers).
Press the [PAGE] key to toggle between the 4
pages, or hold the [PAGE] key depressed for
two seconds to start a rotation of the 4 pages.
Press [PAGE] again to return to manual
operation.
To mix and match the various chart and data displays you wish to have
in the PAGE and WINdows presentation, 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
5
window
2
window
3
We pretend that in this page, window 2 contains the
navigation display (highway), window 3 a chart
display in a large scale for overview, and window 5
a chart display in a smaller scale to enlarge a
certain area.
You now wish to insert the Position display in window 3 instead of the
chart display. This is the procedure:
WIN Press the [WIN] key until the frame around window 3 is highlighted
MENU Call up the menu bar, and…
2,1 then call up the POS menu and select “Position”
- you will now have the Position display in window 3 instead of the
chart display.
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…
2then call up the POS menu - see example next page.

POSITION
WIN
_2_
POS
_1_Position
_2_Dual speed
_3_Speed, course & depth
etc.
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.
)An exception is the radar display, which only can appear in ½
window or full screen, and you can only have the radar display appear
in one page at a time. You can not toggle from page to page and see
different radar displays.

Having selected e.g. 4:NAVIGATION from the menu bar, its associated
menus will drop down. Key in the number next to the function you
wish to call forward, or use the cursor key to highlight the function and
press [ENT].
If you want to switch to a different menu, use the cursor key to move to
the adjacent menu.
Most functions in the menus are general, and can be called forward at
any time, but a few are related to a certain menu(s) and can only be
called forward or activated in the appropriate menu. Inactive functions
in the menu will have a different color from the rest of the functions.
Which window is active (see top line of the menu to the right) can also
have something to do with what functions are available. Use the [WIN]
key to toggle between active windows and keep an eye on the functions
in the menu to see how they may change color.
The menu bar will disappear from the screen at the selection of a
function, or by pressing the [MENU] key. Besides, if not used, it

display, the display will disappear
from the screen, as you have no
