address to AvMap, or an authorized AvMap representative. AvMap will not be responsible for
any losses or damage to the product incurred while the product is in transit or is being shipped
for repair. Insurance is recommended.
LIMITATION OF IMPLIED WARRANTIES - Except as set forth above, all other expressed or implied
warranties, including those of fitness for any particular purpose and merchantability, are hereby
disclaimed. Some states do not allow limitations on warranties, so the above limitation may
not apply to you.
EXCLUSIONS - This warranty does not cover the following: Installation, Finishes, Defects resulting
from installation. Any damage due to accident, resulting from inaccurate satellite transmissions.
Inaccurate transmissions can occur due to changes in the position, health, or geometry of a

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

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 naviga-tion.
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.
Cleaning Procedure for the Chartplotter Screen
Cleaning of the chartplotter screen is a very important operation and must be done carefully.
Since the surface is covered by a antireflective coating, the procedure for cleaning all the
surfaces can be performed using the following procedure: You need a tissue or lens tissue
and a cleaning spray containing Isopropanol (a normal spray cleaner sold for the PC screen,
for example PolaClear by Polaroid). Fold the tissue or lens tissue into a triangular shape,
moisten the tip and use the index finger behind a corner to move the tissue across the
surface, in overlapping side to side strokes. If the tissue is too wet, a noticeable wet film will
be left in its path and you will need to repeat the process. If too dry, the tissue won’t glide
easily, and may damage the surface.

The Moving Map operates in Auto Home, Auto Zoom, and Cursor Mode. The screen will behave
differently based on the mode of operation selected. The Auto Home mode will allow the user to
pan away from his present position to view other parts of the map, and return to present position
automatically when no buttons are pushed for a pre-determined amount of seconds. Auto Zoom
mode will keep your present position, and your destination in the screen at all times. The screen
will automatically zoom in as you get closer. To shut off this function, simply select OFF.
The Cursor Mode (OFF Selected) will allow you to move the map to any position to view data or
details. To return to your present position, just press ‘CLEAR’ while in moving map.
The control for these functions is found in the Moving Map Menu, under Auto Position Mode.

16
To deactivate, press ‘GOTO’ and select “DEACTIVATE”.
1.3.7 Database
The Database function allows the user to access information stored in the data cartridges on
Airports, VOR’s, NDB’s, Intersections and User Waypoints. Searching the Database allows the user
to activate GoTo Flight Plans and locate the item on the map. There are two methods of accessing
the Database information. The first is through the Database function within the Main Menu and the
second is directly from the Moving Map display (see Chapter 3).
1.3.8 Battery Compartment and Batteries
The EKP-IV is designed with a battery compartment for 6 rechargeable AA batteries. It is located
in the rear of the unit underneath the removable knee mount. The unit provides a ‘trickle’ charge
to the batteries when the unit is plugged into external power and powered ON. Rechargeable AA
batteries are required. Install them only after the batteries are fully charged. With fully-charged
batteries, the normal discharge time will be close to two hours, depending upon the condition of
the batteries, as well as the brightness and contrast of the screen settings. AvMap highly recommends
that NiMH AA batteries be used (available from AvMap/Navigation, or from any electronics shop).
DO NOT USE ALKALINE BATTERIES, as they may damage the unit and void the warranty.

17
2 THE BASICS
This chapter provides general information about the functions of the keys and entering data
(connecting the EKP-IV to power and using the antenna are described in Chapter 15).
2.1 THE KEYBOARD
The EKP-IV has 10 keys, which access and control features. Some keys perform different tasks
based on the operation mode. A quick key guide is displayed at the bottom of many menus for
easy reference.
Below we indicate the keys in capital letters enclosed between single inverted commas, for example
‘MENU’. When a key, for example ‘MENU’, must be pressed and held down for more than 1
second it is shown as ‘MENU’ 1 sec.
The POWER key
‘POWER’: press and hold to turn the EKP-IV On.
‘POWER’ 3 seconds: once the EKP-IV has been turned On turns the EKP-IV Off.
‘POWER’: (immediately release!) once the EKP-IV has been turned On displays the Brightness and
the Contrast Menu.
The PAGE key
Displays a list of the 20 nearest objects, including private airports which contain runways of at least
500 ft. in lenght, relative to fix position or cursor position if no fix is available. Press and hold to
access the NavData Page.
The GOTO key
Activates a Flight Plan to the cursor position (in Moving Map) or to selected object (in other
modes).
The ZOOM-OUT key
Shows less detail of a larger area by changing the chart scale and zooming out on the map display.
The CURSOR key
Moves the cursor on the Moving Map, quickly and accurately. Also scrolls to the desired options
in menu page(s).
The ZOOM-IN key
Shows more detail of a smaller area by changing the chart scale and zooming in on the map
display.
The MENU key
‘MENU’: selects the Moving Map Menu.
‘MENU’ 1 sec.: opens Main Menu (equivalent to press ‘MENU’ twice).
The ENTER key
Selects the desired option or confirms selection. Also opens the Cursor/Position Menu.
The CLEAR key
Rejects an action, closes a window or activates Home or Auto Zoom mode.
The CYCLE key
The EKP-IV is equipped with a Cycle Key that allows the user to quickly filter mapping information
on the display. There are three Cycle modes and hitting the Cycle Key one to three times activates

18
them. The Cycle Key is defaulted in the Cycle 1 position that normally activates all features to be
visible on the display. By hitting the Cycle Key once, Cycle 2 is activated and hitting it a secnd time
activates Cycle 3, one last Cycle key activation and the display is back to Cycle 1.
To set user preferences for the Cycle Key:
‘MENU’ + “SELECTIVE DISPLAY” + ‘ENTER’
The Cycles appear in the first three columns and are labeled 1, 2 and 3. In order to adjust at which
Cycle features appear, use the Cursor Control key to highlight an item and hit ‘ENTER’ to remove
the item from appearing. Hit ENTER again to check the item so that it will appear on the display
when that Cycle is activated. Continue to use this procedure to activate features in Cycles 1 - 3 as
desired.
2.2 TURNING THE EKP-IV ON/OFF
Before powering On the EKP-IV, check for the correct voltage (10-35 Volt DC).
2.2.1 Turning On
Press and hold ‘POWER’ for 1 second. The EKP-IV emits one rapid beep sound and a Title page
containing information about the Product name, Software version, library version and cartridges
installed is displayed. This data can also be viewed in the “About” page in the “Main Menu”.
Fig. 2.2.1 - Title page
