Software version 1.51
Warning!!!
A measure of knowledge by the user is required for proper and safe use of the
chart plotter. Read the User Manual and the Warranty completely.
Use Good Judgement
This product is an excellent navigation aid, but it does not replace the need for
careful pilotage and good judgement. Never rely solely on one means of navigation.
Use Care to Avoid Inaccuracies
The Global Positioning System (GPS) is operated by the U.S. Government, which
is solely responsible for the accuracy and the maintenance of GPS. Certain conditions can make the system less accurate.
Accuracy can also be affected by poor satellite geometry.
The accuracy of position fixes is subject to changes in accordance with the Department of Defense civil GPS user policy and
the Federal Radionavigation Plan.

_____Attenzione!___________________________________
L'esposizione del display ai raggi ultravioletti può accorciare la vita dei cristalli liquidi
usati nel vostro plotter cartografico. Questo limite è dovuto alla tecnologia costruttiva
degli attuali display.
Evitare inoltre che il display si surriscaldi per non causare una diminuzione di contrasto che, in casi estremi, può rendere lo schermo completamente nero.
Tale condizione è comunque reversibile durante il raffreddamento.
______Warning!____________________________________
Exposure of display to UV rays may shorten life of the liquid crystals used in your
plotter. This limitation is due to the current technology of the LCD displays.
Avoid overheating which may cause loss of contrast and, in extreme cases, a darkening of the screen. Problems which occur from overheating are reversible when temperature decreases.
______Achtung!____________________________________
Ultraviolette Strahlen können die Lebensdauer vom Flüssigkristalldisplay verkürzen.
Die derzeitige LCD-Technologie bedingt diese verkürzte Lebensdauer.
Überhitzung des Displays durch Sonneneinstrahlung führt zu einem Kontrastverlust
und in extremen Fällen sogar in eine Schwär zung des Bildschirmes.
Bei sinkenden Temperaturen normalisiert sich der Kontrast wieder und die
Bildschirminformation wird wieder ablesbar.
______Attention!___________________________________
L'exposition de votre écran LCD aux ultra-violets lors de soleil intense réduira la
durée de vie de l'afficheur de votre lecteur. Cette contrainte est liée à la technologie
des écrans LCD.
Une augmentation trop importante de température peut obscurer des zones de votre
écran et le rendre ainsi inutilisable (non couvert par la garantie).
______ Aviso!______________________________________
La exposición de la pantalla a los rayos UV puede acortar la vida del cristal líquido
usado en su ploter. Esta limitación se debe a la tecnología actual de las pantallas LCD.
Evitar que la pantalla se caliente en exceso pues puede causar pérdida de contraste y,
en caso extremo, la pantalla puede quedar totalmente negra.
Este problema revierte al enfriarse la pantalla.Table of Contents

Introduction
If you have not used a GPS Charting System before and intend to use your EKP-III for navigating, we suggest that you read this User Manual and make sure you are familiar with its contents.
Throughout this User Manual, the keys are shown in capital letters enclosed between
single inverted commas, for example ‘MENU’.
Menu operations are in bold characters listed by keys sequence with the menu names
enclosed between quotes, for example ‘MENU’ 1 sec . + “SYSTEM SETUP” + ‘ENTER’
+ “FIX SETUP” + ‘ENTER’ means: press and hold down the ‘MENU’ key for 1 second,
using the cursor keys selects the System Setup menu, press ‘ENTER’, using the cursor keys
selects the Fix Setup menu and then press ‘ENTER’.
Terms underlined, for example W
aypoint, are explained in Appendix A “Terms”.
1.1 FEATURES
This electronic charting system integrates the remarkable accuracy of a GPS receiver with a
detailed moving map into a single, easy-to-use, computerized electronic map system. Designed
as a sophisticated navigation infor mation center, the features of the EKP-III allow the user to
Track infor mation and navig ate to points of interest.
Equipped with C-MAP NT
+
cartography, the EKP-III system can be used either with
a C-MAP NT+C-CARD (data card) or as a Track plotter using the inter nal background map.
The EKP-III can be connected to an external GPS or position receiver via a data cable
providing an NMEA0183 data string. Connections to an external receiver, device or an external antenna are made quickly and easily while in the cockpit (see Chapter 15).
The EKP-III contains built-in cartog raphy with coastlines, names of countries, major
cities, highways, lakes and rivers. Additional street, lake and river detail, which enhances the
internal data, can be obtained with C-MAP Aviation’s regional terrestrial librar y.
When the package containing the EKP-III is first opened, please check it for the following contents (if any parts are missing contact the dealer where you purchased the EKP-III):

The Global Positioning System
The Global Positioning System (GPS) is a constellation of satellites that orbit the earth twice a day ,
transmitting precise time and positioning information to anywhere on the globe, 24 hours a day.
The system was designed and deployed by the U.S. Department of Defense to provide
continuous, worldwide positioning and navigation data to U.S. and allied military forces. GPS
broad commercial applications were recognized early in the system’s development, and the U.S.
government decided to allow free access to GPS
signals. Today, GPS
is used in a wide variety
of commercial and scientific applications.
7.1 GPS PAGE
The GPS page shows GPS data in graphic mode, displaying satellite availability and status.
>‘MENU’ 1 sec. + “GPS PAGE” + ‘ENTER’
Fig. 7.1 - The GPS page
This page displays the current status and location of all available satellites in the GPS constellation, referenced to the initial position or last fix.
EKP III USER MANUAL 55
Page 56
On the bottom half of the screen (see previous Fig 7.1) there is a polar representation
of the Azim
uth and Elevation of the satellites used to compute a position fix.
The Ele
vation
is the height of the satellite above the horizon, with 5° (lowest) near the
horizon and 90° (highest) being directly overhead (the EKP-III does not normally use satellites
with Ele
vations lower than 10°). Azimuth is the satellite’s location in relation to true north,
measured clockwise as a bearing
. A satellite with an Azim
uth of 90° is to the east.
The circle contains a number indicating the number of the satellite and it is filled when
it is used for the fix solution. On the left side there are histograms indicating the S/N ratio
(SNR). The bar is filled when the satellite is used for the fix. When a valid fix is received, the
EKP-III displays the current position
coordinates, Date, Time, HDOP, VDOP,GS, TRK and
AL
T on the GPS page.
7.2 GPS RECEIVER SPECIFICATIONS
• Receiver : L1, C/A code, DGPS/WAAS Ready
• Channels :12
• Max Solution Update Rate : 10/sec.
• Cold Star t (avg) : < 45 sec.
• Warm Start (avg) : < 40 sec.
• Hot Star t (avg) : 8 sec.
7.3 HOW GPS WORKS
Each GPS satellite continuously broadcasts two signals: an SPS (Standard Positioning Service)
signal for worldwide civilian use and a PPS (Precise Positioning Service) signal for U.S. and
Allied military use. The SPS
signal is a spread-spectrum signal broadcast at 1575.42 MHz. The
signal is virtually resistant to multipath and nighttime interference and is unaffected by weather and electrical noise. All commercial and consumer GPS
receivers are SPS receivers.
The SPS
signal contains two types of orbit data: almanac and ephemeris. Almanac data
contains the health and approximate location of every satellite in the system. A GPS
receiver
collects almanac data from any available satellite, then uses it to locate the satellites that should
be visible at the receiver’s location. Ephemeris da
ta represents the precise orbital parameters of
a specific satellite.
Receivers listen to signals from many satellites simultaneously and triangulate a posi
tion fix using the interval between the transmission and reception of each satellite signal (a
r
eceiver tracks more satellites than are actually needed for a position fix, so that if one satellite
56 EKP III USER MANUAL
Page 57
EKP III USER MANUAL 57
becomes unavailable, the r
eceiver knows exactly where to find the best possible replacement).
Three satellites are required for two-dimension positioning (which determines position
only) and
four satellites are required for three-dimension positioning (to determine position
and elevation).
7.3.1 ACCURACY
In general, an SPS receiver can provide position information with an error of less than 25
Meter
s and velocity information with an er ror of less than 5 Meter
s per second. For applica-
tions that require much greater accuracy the effects of SA
and environmentally produced errors
can be overcome by using a technique called Dif
ferential GPS (DGPS), which increases over-
all accuracy.
7.3.2 WAAS
The Federal Aviation Administration (F AA), in cooperation with other DOT organizations and
DOD, is augmenting the GPS
/SPS
with a satellite-based Wide Area Augmentation System
(WAAS). WAAS will provide a signal-in-space to WAAS compatible receivers to support en
route through precision approach navigation. After achieving initial operational capability,
WAAS will be incrementally improved to expand the area of coverag e, increase the availability
of precision approaches, increase signal redundancy and reduce operational restrictions.
7.3.3 DIFFERENTIAL GPS
Differential GPS (DGPS) uses a GPS receiver at a fixed point with a known position of submeter accuracy. This is the control unit. The r
eceiver collects data for all visible satellites and
computes predicted satellite ranges, which are compared with actual ranges. The difference is
the satellite range error, which is conver ted to cor rection signals for use by a roving r
eceiver.
It is assumed that this correction will be the same for other GPS
receivers that are in
the same area and are using the same satellites for positioning. If the correction is communicated to other receivers in the area (usually by a beacon on the same site), the range error can
be removed from satellite signals and precise fixes calculated by these receivers.
It should be noted that not all data errors can be cor rected in this way. Errors that are
caused by r
eceiver noise (which is inherent in any GPS receiver) and multipath problems cannot be eliminated with differential corrections. (Multipath errors occur when the receiver’s
antenna “sees” the reflections of signals that have bounced off of surrounding objects.)
Using DGPS
to eliminate the effects of correctable errors requires that the user’s GPS
receiver be connected to a compatible differential beacon receiver and be within range of the
broadcasting beacon. The differential beacon r
eceiver accepts and demodulates the broadcast
corrections, which are then relayed to the GPS
receiver. T he GPS receiver applies the cor rec-
tions to the navigation data it uses to compute a position solution and displays differentially
Page 58
corrected data. Care must be taken to ensure that the DGPS
receiver and the GPS receiver are
compatible for this procedure to be successful.
7.3.4 MONITORING & CONTROLLING THE GPS
The Global Positioning System is monitored and controlled by the U.S. Air Force, which is
responsible for updating and maintaining exact satellite position and signal data accuracy. It is
also responsible for performing maintenance on the satellites, which may require the satellite
being taken off-line. Since the system is subject to periodic updates and changes, the almanac
data broadcast by the satellites is current for a limited time — generally about 14 days.
7.3.5 GPS INFORMATION SOURCES
The needs of the worldwide civil GPS user community are served by the Ci vil GPS Information
Center (GPSIC) in Virginia. The GPSIC is operated and maintained by the U.S. Coast Guard for
the U.S. Depar tment of Transportation. Its primary function is to provide infor mation on the
Global P
ositioning System and satellite status and to serve as a point of contact.
The GPSIC has general GPS
literature available free upon request. The Center also
maintains up-to-date almanac
data and Operational Advisory Broadcasts containing current
constella
tion
status and planned satellite outages.
There are three ways to quickly obtain current information about the Global
Positioning System from the GPSIC:
1. Recorded phone messag e at (703) 313-5907
2. WebSite: www.navcen.uscg.mil
3. Live information at phone (703) 313-5900
There are several GPS
bulletin board services outside the United States, including:

Waypoint & Database
The EKP-III uses three types of Wa
ypoints:
Jeppesen W
aypoints are contained in the C-CARD™ and include Airport, VOR, NDB and
Inter
section Wa
ypoints. Each of these Waypoints is displayed on the Moving Map by an icon.
These W
aypoints can be searched in the Da
tabase Menu and identified on the Moving Map
with Quick Info or Full Info.
Each of these W
aypoints can be used in a Flight Plan, for the Nearest Search or GoTo
functions. When used in a F
light Plan, details regarding the Waypoint are displayed in the
Destination box during flight (when DEST is chosen for display in the Da
ta Window, see Par.3.5.2).
Our Jeppesen library is updated every 28 days. Please contact your local C-MAP office
for update orders and pricing.
User-Defined W
aypoints (also called User Waypoints) are created by the user. T he user can
create unique 8 character names and choose from 16 icons for each waypoint.
Waypoints can be created and edited both on the Mo
ving Map and in the User Waypoint
Database page. Like the Jeppesen Waypoints, they can be used in a Flight Plan, for the Nearest
Search or GoTo functions.
The EKP-III can store up to 1,000 User-Defined W
aypoints within the internal memory.
The internal waypoint memory capacity is shared with Flight Plan waypoints; i.e. if you have 10
flight plans with 10 waypoints stored in the unit memory, there is room for 900 User Waypoints.
Additional W
aypoints can be stored in the optional User C-CARD (see Par. 8.4.2).
Temporar y W
aypoints are created only on the Moving Map and are associated with a partic-
ular F
light Plan. They are named in the for mat WPT001, WPT002 etc. Temporary Waypoints
can be used at the beginning, middle or end of F
light Plans. They can be used as the destina-
tion of a Direct-To F
light Plan, but cannot be accessed in the Nearest function.

where applicable (see Appendix 4 for details).
8.4 USER C-CARD
This feature Is not a vailable in Version 1.32 softwar e and earlier
The EKP-III allows you to download (copy) information to an optional User C-CARD
; thereby allowing you to store additional data externally and reload that information at a later time.
This User C-CARD
also allows you to share data with other compatible chart plotters.
The User C-CARD
is different than the C-CARD containing map detail. Be sure the
C-CARD you are using to store data is labeled as “User”. If you do not already have a User CCARD contact your C-MAP dealer.
New User C-CARD
s must be formatted before use (see following Par. 8.4.1): this
operation initializes the User C-CARD
and prepares it for storing infor mation.
WARNING!!!
A User C-CARD containing data may be reformatted, this operation destroys any data already
on the User C-CARD
.
To perfor m the following functions, begin by inserting the User C-CARD into either
of the C-CARD slots of the EKP-III (see Par. 2.6 for correct inser tion). Then:
>‘MENU’ 1 sec + “DATABASE” + ‘ENTER’ + “USER C-CARD” + ‘ENTER’
After pressing ‘ENTER’ the User C-CARD director y page appears. Us e ‘ ZO O M
IN’/’ZOOM OUT’ to select the function desired.
8.4.1 FORMATTING A USER CARD
The for matting function must be done before using a new User C-CARD: this operation prepares the User C-CARD
to receive and store information. Before you start the formatting pro-
cedure, inser t a new User C-CARD
(see Par. 2.6):
EKP III USER MANUAL 63
Page 64
>‘MENU’ 1 sec + “DATABASE” + ‘ENTER’ + “USER C-CARD” + ‘ENTER’ + “FORMAT”
+ ‘ENTER’
A warning window is shown, select “YES” and press ‘ENTER’ to confirm the format-
ting (select “NO” otherwise).
Once finished, your User C-CARD
is formatted and ready to use. Be sure to label it.
The label will remind you that the User C-CARD
has been formatted and contains data you
may not want to erase.
A used User C-CARD
can be re-formatted. If a used User C-CARD is for matted, all
previously stored data will be lost completely.
8.4.2 SAVING DATA TO USER C -CARD
The saving function stores the desired information onto the User C-CARD:
‘MENU’ 1 sec + “DATABASE” + ‘ENTER’ + “USER C-CARD” + ‘ENTER’ + “SAVE” +
‘ENTER’
You will be prompted to name the file you want to save. Use the cursor keys to name
the f
ile and press ‘ENTER’. You can now choose the type of file you want to save (Routes,
T
r
ack, User P
oints). Choose the file type and press ‘ENTER’. Press ‘ENTER’ again to confirm.
NOTE
The data stored on the User C-CARD will include all items cur r ently stor ed in the units memory for the
category of data. All data is stored as one file with the file name given. The software does not allow for the storage
of single items within the categor y of data, i.e. all flight plans ar e saved with the one file. When naming a file, you
may have trouble finding a name that uniquely identifies the file’s contents. Dates, for example, are often used in filenames; however, they take up several characters, leaving you with little flexibility. The secret is to find a compromise,
a point where you can combine a date with a word, creating a unique filename. The maximum length of the filename
is 8 characters. The characters may be numbers (0, ..., 9), letters (A, ..., Z) and spaces (for example legal identifiers
are “ABC”, “AA”, “12121212”, “A B C”, “1 A 1”, and so on.
8.4.3 LOADING DATA FROM USER C -CARD
The loading function loads from User C-CARD the desired information. Before you start the
loading procedure, inser t the User C-CARD (see Par. 2.6):
‘MENU’ 1 sec + “DATABASE” + ‘ENTER’ + “USER C-CARD” + ‘ENTER’ + “LOAD” +
‘ENTER’
Highlight the file you want to upload into the EKP-III and press ‘ENTER’. Press
‘ENTER’ again to confirm.

8.4.4 DELETING DATA FROM USER C -CARD
Just as you may need to saving files, you may also need to remove old or unnecessary files to
clean up your User C-CARD
. The deleting function erases a f
ile from User C-CARD.
Remember though that this operation permanently erases the f
ile. Before you start the deleting
procedure, inser t the User C-CARD
(see Par. 2.6):
>‘MENU’ 1 sec + “DATABASE” + ‘ENTER’ + “USER C-CARD” + ‘ENTER’ + “DELETE”

Approach Data Procedures
WARNING:
The EKP III C is not certified for use as the only navigation device during Instrument Flight
Rules as established by the FAA. Instrument approach points displayed in the unit are for infor mation only and do
not establish authority for a pilot to fly the IFR approach pr ocedur e in actual instrument flying conditions. For IFR
flight. The final “Approach Segment & Missed Appr oach Point” the EKP is to be used strictly as a monitoring
instrument only.
An approach procedure is a series of pre-determined maneuvres for the orderly transfer of an aircraft, under instrument f light conditions, from the beginning of the initial approach to a point
from which a safe landing may be made visually. Generally, the approach pattern and procedure is
not chosen until arrival in close proximity of the destination airport, since conditions may change
on route. To activate an “Approach” it is necessary to have an active “Flight Plan” or “GOTO”.
For each air port with at least one published final approach, there exists one or more named
approach procedures. Each approach procedure can be related to a runway and to nearby
NavAids (such as ILS, VOR, NDB, GPS...).
9.1 APPROACH FROM THE MOVING MAP
NOTE
You must start with an empty flight plan..
While navigating or planning in the moving map screen, the pilot will not be able to establish
an approach on a flight plan, without changing into the Flight Plan mode, but can place the cursor over the selected airport. To display the quick data box press:
‘ENTER’ 1 sec + ‘ENTER’ (for detailed infor mation).
The detailed infor mation on the airport will be displayed, beginning with the general information and frequencies. By pressing the left ar row, the approaches for the chosen
airport will display in the box and the bearing for the viewed a
pproach will display on the
moving map. By continuing to press the left arrow the other approaches for the airport will
display, the last bearing for the last approach viewed will become white on the moving map
and the bearing for the viewed approach will be displayed in black on the moving map.
EKP III USER MANUAL 67
Page 68
(Note: The white a
ppr
oach bearings will disappear once the screen redraws itself).
9.2 APPROACH FROM FLIGHT PLAN DATABASE
Refer to Chapter 6 for Flight Planning.
Flight Plan mode allows the pilot to plan and activ ate up to ten flight plans with up to 100 individual legs each. Now the EKP III allows the pilot to pre-program an approach at the destination end of the flight plan and to change the approach as desired.
Once an airport is present as a final waypoint in the flight plan, press ‘MENU’ and
“SELECT APPROACH” + ‘ENTER’ and the available approaches for the destination airport will be displayed. Highlight the approach desired, press ‘ENTER’ and the waypoints
associated for that approach will show in the flight plan list. Press ‘ESC’ + ‘ESC’ and the flight
plan will appear on the moving map.
To change the desired approach for the airport, if one is selected
‘MENU’ + ‘MENU’ + “FLIGHT PLAN” + ‘ENTER’ + ‘MENU’ + “CHANGE APPROACH”
- select the approach + ‘ENTER’.
This will substitude the previous approach including the waypoints on the moving map for the
new approach and add the new waypoints to your flight plan and the moving map.
68 EKP III USER MANUAL
Page 69
To remove desired approach
‘MENU’ + ‘MENU’ + “FLIGHT PLAN” + ‘ENTER’ + ‘MENU’ + “REMOVE APPROACH”
+ ‘ENTER’.
9.3 SELECT APPROACH FOR GOTO
If a ‘GOTO’ to an airport is active, pressing “GOTO” from the map will display the GOTO
menu (regardless of your cursors position).
If an approach to the destination airpor t is not yet selected (the approach has to be
present in the Jeppesen® database), the “GOTO Menu” will display “Select Approach”
If an approach is already selected, the “GOTO Menu” will show the options:
“Change Approach” or “Remove Approach”
Selecting “Select Approach” or “Change Approach” will open a new window with available
approaches for the destination airport.
After selecting the desired approach, the EKP III will remove the GOTO destination
airport and re place it with the approach waypoints.
The ‘GOTO’ destination is now the first approach waypoint.
The EKP III will take you to the first point of the approach, and after passing through
this point automatically, will go to each of the other points of the approach.
EKP III USER MANUAL 69
Page 70
Selecting “Remove Approach” removes the approach waypoints from the GOTO destination
replacing them with the corresponding air por t waypoint (that was originally selected).
Activating a GOTO with an Approach from database
If you are in the airports database pag e
‘MENU’ + ‘MENU’ + “DATABASE” + “AIRPORTS”
and the screen is displaying approach infor mation, by pressing ‘GOTO’ you will activate a ‘GOTO’ to the selected air port and automatically opened the “Select Approach” window. If you don’t want to select any approaches just press ESC.

The EKP-III will compute and display Fuel Consumption for each leg of a F
light Plan,
and total fuel needed for the flight in the Flight Plan page (see Chapter 6). When selected for
display, the data fields window will provide information on the flight time remaining before the
reserve fuel has been reached.
NOTE
The Fuel Consumption re pr esents calculated fuel use based on user data. The r eser ve does not r e pr esent
actual fuel available in the aircraft.
Fuel Consumption can be modified en route by increasing or decreasing the fuel burn
rate to match actual usage. T he new fuel computation will be averag ed over the full distance
and provide a good estimate of fuel remaining.
When refueling en route, combine the amount of new fuel and the remaining fuel to
enter the new “Starting Fuel” total for true computation of To Reser ve data.
NOTE
Fuel calculations are only as accurate as the entries made. Always double-check fuel calculations.

Operating Requirements
The EKP-III must be connected to a 10–35 V DC power source and the antenna requires a
clear view of the sky in order to operate.
Fig. 15 - Power and I/O Connector
NOTE
The cable that ends with wires is available as an optional part. Please contact your local C-MAP office
for details.
EKP III USER MANUAL 95
Page 96
15.1 EXTERNAL WIRING
External Power
The EKP-III has a detachable power cable. After connecting the power cable to the EKP-III
via the 7 pin conxall connector, insert the power cable into the aircraft’s cigarette lighter or the
optional battery pack.
External Equipment
External equipment can be connected to the EKP-III through an optional data cable. The
optional data cable terminates in a DB-9 connector.
Fig. 14.1 - DB-9 Connections
15.2 ANTENNA ASSEMBLY & PLACEMENT
The antenna comes with a 5 meter cable with a SMB connector. The antenna is designed for
use inside the aircraft. It can be temporarily mounted on the aircraft’s dashboard using the
included velcro strip.
The antenna must have a clear view of the sky in order to receive satellite signals. GPS
uses “line of sight” signals to locate and track satellites. If the signals are obstr ucted by dense
objects such as aluminum, steel or even heavy ice,the EKP-III will not operate properly. Signals
may also be blocked by heated wind screens (fiberglass, plexiglass and other plastics are normally transparent to GPS
signals).
The antenna can be mounted to any convenient surface that has a clear view of the
sky. If you find that the EKP-III does not locate and track satellites quickly or consistently,
move the antenna. Moving the location of the antenna a few inches often provides a better
view of the sky.
15.3 SECURING THE EKP III
The EKP-III was designed to be mounted on your leg for operation. This will put the EKPIII close at hand and in an easily visible location without interfering with other equipment.
96 EKP III USER MANUAL
Page 97
Use the elastic strap provided to secure the EKP-III to your leg. Position the elastic
strap around your leg with the long looped strip on top. Fasten with the hook and loop closure
at each end of the strap. Hold the EKP-III over the strap on your leg and lower into place.
Press down a little to be sure the strips are secure. If you prefer there are after market mounts
available for attachment to the yoke assembly or the seat rail tracks. Please contact your dealer
for more details on these items.
NOTE
Yoke mounts may not be appropriate for your aircraft. Use care to ensure that the EKP-III does not
obscure the primar y instr uments.

15.6 TROUBLESHOOTING
The following is a brief guide to some of the problems you may experience while using the
EKP-III with common solutions.
15.6.1 POWER
No Power — The power connections are loose or not fully engaged. Make sure all Power Cable
connections are secure. Make sure the power supply is operating properly. Check the fuse located at the end of the cigarette plug. (To open unscrew the middle circle at the tip of the adaptor.)
15.6.2 GPS FIX
Position fix doesn’t change — The signal from one or more satellites has been lost; the positioning information displayed is the most recent available.
Position fixes var y a lot — GPS accuracy is affected by several variables, the most prevalent
of which are the g
eometric quality of the fix. Therefore, the specified accuracy of 15 Meters
RMS
in 2D is statistical, not absolute and assumes the absence of Selective Availability which
was discontinued in April 2000.
The EKP-III is not obtaining position fixes — If the EKP-III is using an internal GPS
Recei
ver, proceed to the GPS
status screen:
>‘MENU’ 1 sec. + “GPS PAGE” + ‘ENTER’
Review the number of satellites in use. If zero, check that the antenna has a clear view
of the sky and that the connections have been made properly. If less than four satellites are in
use, the GPS
receiver may have difficulty receiving a fix. Try repositioning the antenna. A GPS
fix requires a minimum of three satellites and a poor Signal Quality on one or more satellites
may preclude receiving a position
fix.
Verify the user setting for Fix Source is listed as Internal GPS
:
>‘MENU’ 1 sec. + “SYSTEM SETUP” + ‘ENTER’ + “FIX SETUP” + ‘ENTER’ + “FIX
SOURCE” + ‘ENTER’ + “INTERNAL GPS” + ‘ENTER’
If the EKP-III is using an External GPS receiver, proceed to Fix functions screen:
>‘MENU’ 1 sec. + “SYSTEM SETUP” + ‘ENTER’ + “FIX SETUP” + ‘ENTER’
Verify that the Fix Source is listed properly (External NMEA) as indicated in the
System Setup section of this User Manual (see Chapter 13) and that the Baud Rate is set correctly for your GPS
receiver (the EKP-III requires 9600- Baud Rate). Verify that the data cable
connections are proper.
External device is not r esponding — The data port is not turned on or is not outputting
EKP III USER MANUAL 99
Page 100
messages in the correct format. Refer to the external device’s user guide to determine the correct message format. Check the Installation Settings menu and make any necessary changes.
The EKP-III may not be properly connected to the external device. Check all connections to
be sure they are correctly made and secure.
Navigate feature does not work — Blanks are displayed in the navigation data fields until a
GPS
fix has been obtained; this usually occurs within a few Minutes. Also a Flight Plan must
be active to display values for navigation-related information (such as Cr
oss Track Error) and
you must be travelling at least 2 Knots
to display values for velocity-related infor mation (such
as GS
). Activate a Flight Plan and/or increase your speed.
Fluctuations in positioning and navigation data — Small f luctuations in positioning and
velocity-related navigation is normal.
15.6.3 WHEN NOTHING ELSE WORKS
The list above should allow you to solve most of the operating problems you are likely to
encounter. Simply disconnecting the EKP-III from power for a moment may solve your problem as well. If this does not help, try resetting the EKP-III to the factory defaults:
>‘MENU’ 1 sec. + “SYSTEM SETUP” + ‘ENTER’ + “FACTORY DEFAULTS” + ‘ENTER’
If this does not help, you can try one additional memory clear option. This is a factory default RAM Clear that should only be tried after all other attempts have been made. When
using the RAM Clear feature, you will loose all user stored information and the EKP-III will
default to factory settings. Before this step, you have the option of saving user Mar
ks, Track
history and R
outes to a User C-CARD (this is an optional purchase from your dealer). To per-
form a RAM Clear see Par. 15.7.
