CK31 Handheld Computer User’s Manual 3
Chapter 1 — Using the CK31 Handheld Computer
Using the Battery
The CK31 uses an AB1G lithium-ion battery as its main power
source. You must fully charge the main battery before you can
use the CK31. When you change the battery, a backup battery
maintains your status, memory, and real-time clock for at least
10 minutes.
If the battery light blinks or turns on solid, you cannot restore
factory defaults or perform a warm or cold boot on your CK31
by using the I key. You must replace the battery with a fully
charged battery before you can restore factory defaults or boot
your CK31.
The lithium-ion battery pack that is used in this device may
present a fire or chemical burn hazard if it is mistreated. Do
not disassemble it, heat it above 100°C (212°F) or incinerate
it.
Avertissement: Le paquet de piles d’ions de lithium qui est
utilisé dans cet appareil peut presenter un risque feu ou un
risque chimique de brûlure s’il est maltraité. Il ne faut pas le
désassembler, le réchauffer à une température plus élevée que
100°C (212°F) ou l’incinérer.
Removing the main battery when the backup battery low or
critically low icon displays on the taskbar may cause your
CK31 to cold boot and you may lose data.
Attention: L'enlèvement de la batterie principale quand le
bas de secours de batterie ou les affichages en critique bas
d'icône sur le taskbar peut causer votre CK31 à la botte
froide et de vous peut perdre des données.
If you fail to replace the battery immediately, you may lose
important data or applications.
Attention: Si la batterie n’est pas remplacée immédiatement,
des données ou applications importantes risquent d’être
perdues.
4 CK31 Handheld Computer User’s Manual
Dispose of used battery packs promptly. Keep away from
children. Contact your local Intermec sales representative for
replacement batteries.
Several factors determine the life of your battery such as extreme
temperatures, input devices, and your usage. For example, if you
use a tethered scanner every day, you will need to replace your
battery more often than someone who uses an internal scanner.
Charging and Installing the Battery
Make sure you fully charge the AB1G battery before you use
your CK31. You can charge the battery before or after you
install it into the CK31.
To charge the battery
• Either insert the battery into the AC1 4-slot battery charger
or place the CK31 with battery installed in the AC2 4-Bay
Charging Dock, AC3 8-Bay Charging Dock, AD1 1-Bay
Communications Dock, or AD2 4-Bay Communications
Dock. For more information on these accessories, see page
98.
Chapter 1 — Using the CK31 Handheld Computer
Use the next table to understand how long it will take to charge
your batteries in each of the CK31 charging or communications
dock accessories.
Charging Times for CK31 Batteries
CK31 Accessory Battery Charging Time
AC1 4-Slot Battery Charger 5 hours
AC2 4-Bay Charging Dock 5 hours
AC3 8-Slot Charging Dock 5 hours
AD1 1-Bay Communications Dock 3 hours
AD2 4-Bay Communications Dock 5 hours
To install the battery
• Insert the tabs on the bottom of the charged battery into the
CK31 and snap the battery into place.
CK31 Handheld Computer User’s Manual 5
Chapter 1 — Using the CK31 Handheld Computer
Inserting the AB1G Battery
Maximizing Battery Life
There are several things that you can do to extend the life of
your fully charged battery.
AB1G
battery
• Verify that Radio Power Management is enabled (Fast PSP).
Enabling radio power management allows your radio to
switch between awake and sleep modes based on network
traffic. If you use the default setting of disabled (CAM), you
will have the best network performance (data throughput) but
it will draw the most power from your battery.
• Verify that the backlight timeout is set to 15 seconds.
• Verify that each setting under Power Management has a value
of 1 minute for a combined automatic shutoff time of 3
minutes.
You can use Intermec Settings to easily make all of these
configuration changes. For help, see “Configuring the CK31
Locally With Intermec Settings” on page 28.
6 CK31 Handheld Computer User’s Manual
Checking the Battery Status
The easiest way to tell the status of your battery is to look at the
battery icon in the status bar of your CK31. If you do not see a
battery icon, your battery has a good charge.
Battery Icon Status
Icon Status
You can also check the battery status by looking at the Battery
light on the front of the CK31 or by using the battery
diagnostics screen. For help using the Battery light, see
“Understanding the Status Lights” on page 17. For help using
the Battery Information diagnostic screen, see “Battery
Information” on page 74.
Chapter 1 — Using the CK31 Handheld Computer
Battery has a medium charge. You should be able to work for
several more hours before changing batteries.
Battery is low. You need to replace the battery soon.
Battery is critically low. You need to replace the battery now.
Using the Keypad
Your CK31 has a 52-key full alphanumeric keypad. The 52-key
full alphanumeric keypad is designed for applications that enter
mainly numeric data (0-9) and that may need to enter the entire
alphabet. The keypad also provides function keys (F1-F24) and
special characters, symbols, and functions by pressing colorcoded key sequences.
You can order the CK31 keypad with an international overlay.
The international overlay supports English and many Western
European languages, such as French, German, Italian,
Portuguese, and Spanish. You enter all of the characters and
functions printed above the keys just like you would on a
standard keypad.
The CK31 supports TE 2000 VT100/220/320/340 and ANSI,
TE 2000 5250, and TE 2000 3270. When you order the CK31
with a TE 2000 application, you must order the corresponding
keypad overlay.
CK31 Handheld Computer User’s Manual 7
Chapter 1 — Using the CK31 Handheld Computer
Use the TE 2000 keypad overlays to enter the same keys that
you can enter on a VT/ANSI keyboard, and IBM 5250
keyboard, or an IBM 3270 keyboard.
Like the standard CK31 overlay, the TE 2000 keypad overlays
let you enter all the characters printed on or above the keys. The
terminal emulation keypads also come with the same colorcoded keys that are on the standard overlay.
For more help using TE 2000 terminal emulation, see the TE
2000 programmer’s guide.

Scanning Bar Codes
Do not look directly into the window area or at a reflection
of the laser beam while the laser is scanning. Long-term
exposure to the laser beam can damage your vision.
Avertissement: Ne regardez pas directement la réflexion d’un
rayon laser ou dans la fenêtre du laser lorsque celui-ci est en
opération. Si vous regardez trop longtemps un rayon laser,
cela peut endommager votre vue.
Use the scanner to scan and enter bar code data. The type of
scanner you are suing and the type of bar code you are decoding
determines the way you scan the bar code. The CK31 supports
the scanning of 1D linear bar codes and 2D images depending
on the scanner model in your CK31.
When you unpack the CK31, these bar code symbologies are
enabled:
• Code 39
• Code 128
• PDF417
• UPC/EAN
• DataMatrix
If you are using bar code labels that are encoded in a different
symbology, you need to enable the symbology on the CK31. Use
Intermec Settings to enable and disable symbologies for your
scanner. For help understanding how to use Intermec Settings,
see “Configuring the CK31 Locally With Intermec Settings” on

Synchronizing the CK31 System Time With a Time Server
It is important that the time on all of your CK31s be
synchronized with a network time server to ensure real-time
communications and updates. Network time servers acquire
Coordinated Universal Time (UTC) from an outside source
such as the U.S. Naval Observatory (USNO). The CK31 uses
Simple Network Time Protocol (SNTP) to synchronize with a
network time server.
The default reference time server is the USNO
(tock.usno.navy.mil). To synchronize the time on your CK31
with this time server, you must have a valid connection to the
Internet. You can also synchronize the CK31 system time with a
corporate network server within your firewall that is SNTP
capable. To use an internal corporate network server, you need
to set the domain name in the registry.

Configuring Security
The CK31 provides three types of security for your wireless
network:
• Wi-Fi Protected Access (WPA)
• 802.1x
• WEP
This section explains how to configure security on your wireless
CK31. If you choose not to use security, see “Disabling
Security” on page 53. Intermec always recommends that you
implement security.
You must use either Microsoft or Funk security to implement
your security solution. For details, see the next section,
“Choosing Between Microsoft and Funk Security.”
CK31 Handheld Computer User’s Manual 37
Chapter 2 — Configuring the CK31
Note: If you are using 802.1x security, this section also assumes
that your authentication server and authenticators are properly
configured. For more information on the different types of
security, see the MobileLAN™ secure 802.1x Security Solution
Installation Guide (P/N 073134) available at
www.intermec.com.
Choosing Between Microsoft and Funk Security
Before you can implement a security solution on the CK31, you
need to choose between Microsoft and Funk security:
• Microsoft security is the default setting. If you want to use
Microsoft security, you can start configuring your WPA,
802.1x, or WEP security now.
• Funk security provides everything you get with Microsoft
security plus the addition of CCX v1.0 compliance. Funk
security enables you to use LEAP and TTLS authentication
on your CK31.
If you choose to use Funk security, you need to:
• select Funk security as your security choice.
• select a profile.
Note: Your security choice does not depend on your
authentication server. For example, you can choose Funk
security if you use Microsoft Active Directory® to issue
certificates.
Selecting Funk as Your Security Choice
The default security setting is Microsoft. If you want to use
Funk security, you need to select it as your security choice.
To select Funk security as your security choice
1 Tap the Start icon or press C and then B. The Start menu
appears.
2 Select Intermec Settings. The Intermec Settings application
appears.

settings.
7 Configure your security settings.
Using WPA Security
Wi-Fi Protected Access (WPA) is a strongly enhanced,
interoperable Wi-Fi security that addresses many of the
vulnerabilities of Wired Equivalent Privacy (WEP). Instead of
WEP, WPA uses Temporal Key Integrity Protocol (TKIP) for
its data encryption method.
Currently, WPA satisfies some of the requirements in the IEEE
802.11i draft standard. When the standard is finalized, WPA
will maintain forward compatibility.
WPA runs in Enterprise (802.1x) mode or PSK (Pre-Shared
Key) mode:
• In Enterprise mode, WPA provides user authentication using
802.1x and the Extensible Authentication Protocol (EAP).
That is, an authentication server (such as a RADIUS server)
must authenticate each device before the device can
communicate with the wireless network.
• In PSK mode, WPA provides user authentication using a
shared key between the authenticator and the CK31. WPAPSK is a good solution for small offices or home offices that
do not want to use an authentication server.
To use WPA security, you need:
• an authentication server (Enterprise mode only).
Note: You can also use a MobileLAN access point with
software release 1.80 or later as an authentication server. For
help, see the MobileLAN access WA2XG System Manual (P/N
074921).
• an access point with an 802.11b/g radio that supports WPA.
• a CK31 with the 802.11b/g radio and the 802.1x/WPA
security option.

Using LEAP Security
Lightweight Extensible Authentication Protocol (LEAP), also
known as Cisco-Wireless EAP, provides username/passwordbased authentication between a wireless client and a RADIUS
server. In the 802.1x framework, traffic cannot pass through an
Ethernet hub or wireless network access point until it
successfully authenticates itself.
The station must identify itself and prove that it is an authorized
user before it is actually allowed to use the LAN. LEAP also
delivers a session key to the authenticated station, so that future
frames can be encrypted with a key that is different than keys
used by other sessions.
CK31 Handheld Computer User’s Manual 47

Developing Applications for the CK31
The CK31 Handheld Computers run applications programmed
in Microsoft Embedded Visual C++. The CK31 can also run
applications developed for the .NET Compact framework using
Microsoft C# and Visual Basic.
Use this section to understand the hardware and software you
need to:
• develop a new application for the CK31.
• develop a web-based application for the CK31.
• convert a Trakker Antares application to a CK31 application.
Developing a New Application
Use the Intermec SDK to develop new applications to run on
the CK31. The Intermec SDK is a library of C++ language
functions you can use to create applications for the CK31.
See the SDK online user’s manual for help developing your
application. The Intermec CK31 SDK User’s Manual contains
hardware and software requirements, all of the functions that are
supported by the CK31, and how to use these functions. The
SDK is part of the Intermec Developer’s Library (IDL), which is
available on CD (P/N 235-114-001) or as a download from the
Intermec web site at www.intermec.com.
You need these hardware and software components to use the
Intermec SDK:
• Pentium PC, 400 MHz or higher
• Windows 2000 (Service Pack 2 or later) or Windows XP
(Home, Professional, or Server)
• For native C++ development, Microsoft eMbedded Visual
C++ version 4.0 with eVC++ Service Pack 2
• For .NET Development and Compact Framework (C# and
VB.NET), Microsoft Visual Studio .NET 2003
• 128MB RAM (196MB recommended)
56 CK31 Handheld Computer User’s Manual
Chapter 3 — Developing and Installing Applications
• 360MB hard drive space for minimum installation (720MB
for complete)
• CD-ROM drive compatible with multimedia PC
specification
• VGA or higher-resolution monitor (Super VGA
recommended)
• Microsoft Mouse or compatible pointing device
Developing a Web-Based Application
You can develop web-based data collection applications for use
on the CK31. For help, see any HTML source book. The CK31
contains Internet Explorer (IE) 6.0 for Windows CE or iBrowse
for you to use. The Microsoft standard IE 6.0 is available from
the desktop and provides all of the common elements you expect
to find. iBrowse is also available from the desktop and provides a
locked-down browser with IE 6.0 compatibility.
To open Microsoft Internet Explorer or iBrowse
• Double-tap Internet Explorer or iBrowse from the desktop.
The Internet Explorer or iBrowse default window appears.
Converting a Trakker Antares Application to a CK31 Application
If you have an existing Trakker Antares application that you
would like to run on the CK31, you can use the PSK to convert
it. The Intermec PSK is a set of libraries and tools that you use
to convert your existing Trakker Antares C applications into
C++ applications for use on the CK31.
The CK31 does not support all Trakker Antares PSK functions.
You may need to rewrite parts of your application when
converting it for use on the CK31. See the online Intermec PSK
User’s Manual for a list of functions that are not supported.
You need these hardware and software components to use the
PSK:
• PC with at least 1 MB of free disk space running Microsoft
Windows 2000/XP
CK31 Handheld Computer User’s Manual 57
Chapter 3 — Developing and Installing Applications
• Microsoft embedded Visual C++ version 4.0 with Service
Pack 2
• Intermec SDK and development tools
• Intermec PSK, which contains these files and utilities:
• PSK functions library
• Header files
• Example files
The PSK is part of the Intermec Developer’s Library (IDL),
which is available on CD (P/N 235-114-001) or as a download
from the Intermec web site at www.intermec.com.
Installing Applications on the CK31
There are several ways you can install applications on the CK31:
• You can package your application as a cabinet (.cab) file.
• If you have a simple application, you may only need to deliver
the .exe file.
• You can copy a directory structure that contains the
application, supporting files, DLLs, images, and data files.
Intermec recommends using CAB files to install your
applications. The CK31 uses standard Windows CE CAB files
and will install third-party CAB files. Before the CK31 executes
a CAB file, it marks the file as read-only so that it will not be
deleted after installation. After the CAB file is extracted, the
CK31 automatically saves any changes you have made to the
registry or file system so that they will persist through a cold
boot. This process means that you will not have to reinstall your
applications when your battery goes dead or you perform a cold
boot.
Intermec recommends that you store your applications in the
CK_FFS folder where they can persist through a cold boot. The
CK_FFS folder is an area of storage that is part of the CK31
flash memory. This storage area is not deleted during a cold
boot.
58 CK31 Handheld Computer User’s Manual
Chapter 3 — Developing and Installing Applications

62 CK31 Handheld Computer User’s Manual
Chapter 3 — Developing and Installing Applications
Installing Applications Using Your SD Card
If you have an SD card for your CK31, this is the best place for
you to install applications.
To install applications using the SD card
1 If you are using an SD card reader, remove the SD card from
the CK31 and place it in the reader. For help, see “Using the
SD Card” on page 23.
2 Copy your application file to the SD card.
If you are using ActiveSync, an FTP server, or Wavelink
Avalanche to copy the files to the SD card, place the
application in the SDMMC Disk folder located in My
Computer.
3 If you are using an SD card reader, insert the SD card back
into the CK31.
4 Navigate to the SDMMC Disk folder and run your
application.
Installing Applications Using the FTP Server
The CK31 has a built-in FTP server that connects to a network
through the 802.11b/g radio. You can use the server to transfer
your application file to the CK31. Another benefit of using the
FTP server is that you can create FTP scripts to automate the
process of copying your files to the CK31. This option is useful
when you need to send files to a large number of CK31s.
If you want to disable the FTP server, use a CAB file or another
method to modify the registry key
HKEY_LOCAL_MACHINE\COMM\FTPD. You need to set
the value IsEnabled (a REG_DWORD) to zero (0). If you set
the value to zero, the Web server will not accept connections
from the network, even from the local host.
CK31 Handheld Computer User’s Manual 63
Chapter 3 — Developing and Installing Applications
Installing Applications Using Wavelink Avalanche
You can use the Wavelink Avalanche device management system
to install applications on all of your wireless CK31s. The CK31
ships with the Avalanche Enabler already loaded on it.
Each time the Avalanche Enabler is activated (typically on a
warm boot), the CK31 attempts to connect to the Avalanche
Agent. When the CK31 connects to the agent, the Agent
determines whether an update is available and immediately starts
the software upgrade, file transfer, or configuration update.
To use Avalanche to remotely manage the CK31
1 Install software packages and updates for the CK31 using the
Avalanche Administrative Console.
2 Schedule the CK31 updates or manually initiate an update
using the Avalanche Administrative Console.
For more information on using Wavelink Avalanche, contact
your local Intermec representative or visit the Wavelink web site
at www.wavelink.com.
Launching Your Application Automatically
To launch your application automatically on the CK31 every
time you perform a warm or cold boot, make sure your CAB file
places a shortcut to your application in the \Windows\StartUp
folder.
Setting or Changing the CK31 Password
When you initially start the CK31, there is no password to
protect access to the CK31. Anyone can turn on the CK31 and
access all of the information and tools loaded on it. When you

Backing Up Your Files
The CK31 makes it easy for you to make a backup copy of all
files you have installed or modified on the computer that are not
already located in the SDMMC Disk or CK_FFS folders. When
you make a backup copy of the file system, the CK31 saves the
file system to a folder called Persistent Copy. This folder and all
of the files and subfolders it contains, are automatically restored
when the CK31 cold boots.
You should back up your files any time you want to make
permanent changes to the files in the Persistent Copy folder.
You also need to back up the files when you want to
permanently delete a file. When you install a CAB file, the
CK31 automatically performs this backup process.
To back up your files
1 Tap the Start icon or press C and then B. The Start menu
appears.
2 Select Intermec Settings.
3 From Intermec Settings, select Device Settings > File
Backup.
