1.5.1
Touch Screen Calibration
To calibrate the screen, touch the center of each target in
the order that it appears on the screen, as follows:
1)
Upper left corner
2)
Lower left corner
3)
Lower right corner
4)
Upper right corner
5)
Center of screen
6)
Touch box in center of screen
If target 6 does not occur within 10 seconds of target 5’s
completion, the calibration routine will assume an error
has occurred and start over. Once all 6 targets have been
touched, the touch screen is calibrated. To verify calibra-
tion, drag the stylus across the screen from top to bottom
and then left to right. If the cursor does not track the stylus
properly, repeat the calibration process.
1.5.2
Terminal
A terminal window allows access to the operating system
and applications from the command line. To type com-
mands, touch the Virtual Keyboard task box or use an
USB keyboard which has been plugged in.
1.5.3
Virtual Keyboard
The Virtual Keyboard application is a Virtual Keyboard
that allows the user to enter characters without having an
external keyboard attached.
1.5.4
Link Status
The Link Status application displays the strength of the
radio signal from the base station and the strength of the
tablet’s batteries. Additionally, this application allows the
user to set the length of idle time desired before the
screen dims. To set the idle time, touch the box next to
“Dim Screen” so a check mark appears in it. Select a
length of time and touch the “Apply” button to execute and
save the selection.
1.5.5

1.5.6

The RealPlayer application allows the WebPAD system to
play RealAudio
®
and RealVideo
®
clips from the web.
1.5.7
The email tool allows the user to compose, send, retrieve
and store emails in a variety of folder configurations. The
icons across the top of the email tool are labeled with their
functionality. The frame along the left side of the tool
shows the various mail folders that have been configured
on the system. The upper frame on the right side lists all
of the emails contained in a particular mail folder. The
lower frame on the right displays the text of the selected
email.
Before using the email tool, it must be properly config-
ured. To enter configuration mode, touch the “Config” icon
in the upper left corner of the email tool. The “Incoming
Server” and “Outgoing Server” sections must be filled out
completely. Contact the administrator of the mail system if
configuration assistance in needed. Also, the user should
fill out the “General” and “Composition” sections as com-
pletely as they like. When all the sections have been filled
out, touch the “Save” icon at the top of the tool. The tool
should now be operational. If problems occur, contact the
administrator.
1.5.8
News
Selecting the “news” icon on the application launcher
brings up a browser window and loads www.dejan-
ews.com. Although the “news” icon is not configurable, the
default page can be altered by configuring a user-defined
button and changing the www.dejanews.com part of the
URL. Once the user-defined button has been configured,
the new page can only be accessed via that button. The
“news” icon will always launch the original URL.
1.5.9
Browser
The WebPAD system uses the QNX Voyager™ web
browser which has been customized for the WebPAD sys-
tem.
The icons along the top of the browser window provide
basic browser functionality: back, forward, reload, and
stop loading. To the right of the icons is the URL text box
that allows the user to enter a new internet address or
view previously selected sites. The icon in the upper right
corner is used to close the browser.
The icons on the left side of the browser window provide
functionality beyond basic browsing. These functions
include: bringing up a favorite web site window, adding a
web site to the list of favorites, jumping to the user’s favor-
ite search engine and cycling through the various font
types and sizes.
The icon in the upper left corner of the browser window
has multiple functions. When the icon appears as a sailing
ship, the WebPAD system is in the process of loading the
requested web site. When the icon appears as a toolbox,
the WebPAD system has finished loading the desired
page. Touching the icon puts the WebPAD system in Con-
figuration mode and stops the loading of any page cur-
rently
being
loaded
(see
Section
2.0
“System
Configuration”).
When a “mailto:” link is selected within the browser, a
“Send Mail” window will open. The user then fills out the
subject and contents of the email and touches the “Send”
button to deliver the mail to the server specified in the
“EMail Server” (see Section 2.1.4 “Browser>Network”).
Selecting the “Cancel” button in the “Send Mail” window
aborts the mail delivery operation.
1.5.10 Low Battery Warning
This application warns the user when the battery is about
to run out of power. Upon seeing this warning, the user
should power of the tablet.
