For a complete list of accessories, see “Accessories for the CK31”
on page 139.

What’s New?
The CK31 is now available with a near-far range area imager.

Using the Battery
The CK31 uses a model AB1G (P/N 318-020-xxx) lithium-ion
battery as its main power source. You must fully charge the main

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.
To ensure maximum battery life and product performance,
periodically replace the rechargeable lithium-ion battery.
Contact your local Intermec sales representative for replacement
batteries.
Note: The AB1G battery is designed to provide more than
a full shift of daily use. However, battery life depends on
individual usage patterns. Conditions such as wireless
coverage, power settings, roaming frequency, applications in
use, number of radios in use, ambient temperature, lithiumion battery maintenance, and individual use cases have an
effect on overall battery performance.
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. Dispose of used battery packs promptly. Keep away from
children.
Removing the main battery when the backup battery low or
critically low icon appears on the taskbar may cause your
CK31 to cold boot and you may lose data.

CK31 Handheld Computer User’s Manual

Chapter 1 — Using the CK31 Handheld Computer

If you fail to replace the battery immediately, you may lose
important data or applications.

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
139.

Maximizing Battery Life
There are several things that you can do to extend the life of
your fully charged 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 (User Idle,
System Idle, and Suspend) 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
With Intermec Settings” on page 40.

CK31 Handheld Computer User’s Manual

Chapter 1 — Using the CK31 Handheld Computer

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

diagnostic screen, see “Battery Information” on page 98.

Using the Keypad
Your CK31 has one of the following keypad overlay options:
• 42-key large numeric and function
• 50-key full alphanumeric
• 52-key full alphanumeric
You can order all versions of 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.
Note: You must use the color-coded keys to access several
hidden characters (such as { and }) on the CK31 keypad. For
more information on the hidden characters, refer to “Typing
Characters Not Printed on the Keypad” on page 142.

CK31 Handheld Computer User’s Manual

Chapter 1 — Using the CK31 Handheld Computer

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. 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 color-coded keys that are on
the standard overlay.
For help using TE 2000 terminal emulation, see the TE 2000

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.
Use the scanner to scan and enter bar code data. The type of
scanner you are using 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. Plus, the way you scan bar
codes is different if you are using an integrated handle or a
scanner attached to the serial port.
When you unpack the CK31, these bar code symbologies are
enabled:
• Code 39
• Code 128
• PDF417 (if supported)
• UPC/EAN
• DataMatrix (area imagers only)
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, see “Configuring the CK31 With
Intermec Settings” on page 40.

Scanning With the Standard or Near-Far Range Area Imager
Your CK31 may come with one of two types of area imagers:
• A standard area imager
• A near-far range area imager
Both area imagers allow you to scan 2D bar code symbologies
and supports omni-directional (360°) scanning. Omnidirectional scanning means that you can position the CK31 in
any orientation to scan a bar code label.

Scanning with the Standard Area Imager
The standard area imager comes equipped with an aiming beam
to help you scan bar codes. Use the following procedure to scan
a bar code label with the standard area imager.
To scan a bar code label with the area imager
1 Press I to turn on the CK31.
2 Point the scanner window at the bar code label and hold the
CK31 steady a few inches from the label.
3 Press the Scan button on the keypad or pull the trigger on a

available from the Help menu in the console.

Synchronizing the CK31 System Time With a Time Server
To ensure real-time communications and updates, the time on
all of your CK31s needs to be synchronized with a network time
server. 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.

Chapter 2 — Configuring the CK31

The Wireless Printing applet is available in the Control Panel
and separates the task of wireless printing setup from other
Bluetooth management tasks.
The Wireless Printing applet uses the concept of a “current
wireless printer.” The CK31 connects to the current wireless
printer when your application opens the wireless printing COM
port on the CK31. If there is no current wireless printer selected
on your CK31, there is no wireless printing COM port
registered on your CK31. You must select a current wireless
printer on your CK31, as described in the next section,
“Selecting the Current Wireless Printer on the CK31.”
The Wireless Printing applet performs these tasks on the CK31:
• Helping you select the current wireless printer
• Storing the current wireless printer in the registry
• Registering/deregistering the wireless printing COM port
• Storing the wireless printing COM port in the registry as the
WPort
Specifically, the current wireless printer is registered and
deregistered on Bluetooth stack load/unload. If you select a
different current wireless printer, the existing wireless printing
COM port is deregistered and the new one is registered instead.
The Wireless Printing applet uses the Bluetooth COM Port
Control to handle COM port registration/deregistration.

Selecting the Current Wireless Printer on the CK31
By default, there is no current wireless printer selected on the
CK31.

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 802.1x (Enterprise) 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.

CK31 Handheld Computer User’s Manual

Chapter 2 — Configuring the CK31

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 system manual for your access point.
• 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.
The CK31 also supports Wi-Fi Protected Access 2 (WPA2) if
you are using Funk security. WPA2 is a product certification
available through the Wi-Fi Alliance that certifies wireless
equipment is compatible with the 802.11i standard. WPA2 uses
the Advanced Encryption Standard (AES) for data encryption.
WPA2 runs in 802.1x (Enterprise) mode or PSK (Pre-Shared
Key) mode:
• For WPA2-802.1x mode, WPA2 requires authentication in
two phases; the first is an open system authentication and the
second uses 802.1x and an Extensible Authentication
Protocol (EAP) authentication method.
• In PSK mode, WPA2 provides user authentication using a
shared key between the authenticator and the CK31. WPA2PSK is a good solution for small offices or home offices that
do not want to use an authentication server.

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.

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 resource kits to develop new applications to
run on the CK31. The Intermec resource kits are a library of
C++ and .NET components grouped by functionality that you
can use to create applications for the CK31. The resource kits
are part of the Intermec Developer Library (IDL), which is
available as a download from the Intermec web site at
www.intermec.com/idl.
You need these hardware and software components to use the
Intermec resource kits:

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 Antares
Migration Resource Kit to convert it. The Antares Migration
Resource Kit 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 functions. You
may need to rewrite parts of your application when converting it
for use on the CK31. See the resource kit for a list of functions
that are not supported.
You need these hardware and software components to use the
resource kit:
• PC with at least 1 MB of free disk space running Microsoft
Windows 2000/XP
• Microsoft embedded Visual C++ version 4.0 with Service
Pack 2
• Antares Migration Resource Kit

CK31 Handheld Computer User’s Manual

Chapter 3 — Developing and Installing Applications

The resource kit is part of the Intermec Developer’s Library
(IDL), which is available from the Intermec web site at
www.intermec.com/idl.

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.
You can have your CAB files place your application in any of
these memory locations on the CK31:
• The RAM based file store (anywhere in the root \ directory)
• The Flash File System (the CK_FFS folder)
• On the SD card (SDMMC folder)
Intermec recommends that your CAB files place applications in
the Flash File System or on the SD card. Files in these nonvolatile storage locations are preserved through a cold boot.
You can also place applications in RAM, and they will
automatically be backed up to the Flash File System
(\CK_FFS\Persistent Copy folder). These files will be preserved
through a cold boot, or a complete battery drain and
accompanying cold boot.

CK31 Handheld Computer User’s Manual

Chapter 3 — Developing and Installing Applications

If you have an SD card inserted in your CK31, it appears as the
SDMMC Disk folder. This folder is the recommended location
for placing your application installation files.

the CK31:
• ActiveSync
• SD Card
• FTP Server
• Wavelink Avalanche
• SmartSystems Console
The following sections explain how to use each one of these
processes to install your application on the CK31.

Installing Applications Using ActiveSync
You can use ActiveSync to establish a connection between your
PC and the CK31. ActiveSync allows you to transfer files,

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 “Installing
the SD Card” on page 34.
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

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.
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.

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.

Problems With Wireless Connectivity
Problem

Solution

When you turn on the CK31
after it was suspended for 10-15
minutes or longer, it can no
longer send or receive messages
over the network.

The host may have deactivated or lost your current
terminal emulation session. In a TCP/IP direct connect
network, you need to turn off the “Keep Alive” message
(if possible) from the host so that the TCP session is
maintained while a CK31 is suspended.

The network connection icon is
in the status bar, but the host
computer is not receiving any
data from the CK31.

In a UDP Plus network, there may be a problem with
the connection between the Intermec Application
Server and the host computer. Check with your
network administrator or see the user’s manual for the
Intermec Application Server.
In a TCP/IP network, there may be a problem with the
connection between the access point and the host
computer. Check with your network administrator or
use your access point user’s manual.

The no network connection
icon (
) appears on the status
bar. The CK31 is not
communicating with the access
point.

• The CK31 is not connected to the access point.

Make sure the access point is turned on and
operating. You may also be using the CK31 out of
range of an access point. Try moving closer to an
access point to re-establish communications.
• Make sure the CK31 is configured correctly for your

network. The radio parameters on the CK31 must
match the values set for all access points the CK31
may communicate with. For help, see “Configuring
802.11b/g Radio Communications” on page 45.
• If you have an 802.11b radio, the radio initialization

process may have failed. Try resetting the CK31. See
“Booting the CK31” on page 125.
• If you have tried these possible solutions and the no

network connection icon still appears, you may have
a defective radio card. For help, contact your local
Intermec service representative.
The CK31 is connected to the
Intermec Application Server or
host computer and you move to
a new site to collect data. The
network connection icon was
visible but now the no network
connection icon ( ) is visible.

You may have gone out of range of an access point. Try
moving closer to an access point or to a different
location to re-establish communications. Once you are
in range again, the network connection icon appears
again. Any data you collected while out of range is
transmitted over the network.

Problems With Wireless Connectivity (continued)
Problem

Solution

While configuring or using
wireless printing, you see the
message, “The Bluetooth COM
port does not exist [55]. This is
probably because the computer
was just resumed. Please wait a
few seconds and try again.”

If you recently resumed the CK31, wait a few seconds
and try again.

While configuring or using
wireless printing, you see the
message, “Bluetooth is off.
Would you like to turn it on
and continue?”

Tap Yes to dismiss the message. Follow the instructions
in “Turning On Bluetooth Power” on page 51 to turn
on the power to the Bluetooth radio.

Otherwise, you need to make sure that the device you
selected as the current wireless printer is a printer, is
turned on, and is discoverable.
To learn about the current wireless printer and the
Bluetooth COM port, see “Creating an Application
That Lets You Print Wirelessly” on page 51.

Problems Transmitting Data Through the Serial Port
If you are having problems sending or receiving data through the
integrated serial port on the CK31, check these possible
problems:
• Make sure the CK31 is connected to the PC, host computer,
or RS-232 serial device using the appropriate cable adapter
and null modem cable.
• If the CK31 is in a communications dock, make sure that the
communications dock is connected to the serial device using
the appropriate cable.
• Make sure that ActiveSync is not connecting to the CK31
through the serial port.
• You cannot use the decoded serial adapter or AA2 to connect
to any device other than a decoded scanner. The CK31 autodetects the serial adapter or AA2, and the scanner software
makes the COM port unavailable. Instead, use the AA3 to
connect a device like a printer to the CK31. The AA3
requires an external power source.
For more information on using the serial port, see “Configuring
Serial Communications” on page 58.

Problems While Scanning Bar Codes
Problem

Solution

You cannot see a red beam of light
from the scanner when you press the
Scan button and aim the scanner at
a bar code label.

Make sure you are using a supported scanner, as
listed in “Attaching a Scanner to the Serial Port”
on page 30. If you are using a supported scanner,
try these solutions in order:
• You may be too far from the bar code label.
Move closer to the bar code label and try again.
• You may be scanning the bar code label
“straight on.” Change the scanning angle and
try again.
• You can test the effective range of the scanner.
Move within 61 cm (2 feet) of a wall and try
again. You must be within the scanning range
to scan bar code labels. For help, see “Scanning
Bar Codes” on page 22.

When you release the Scan button
or handle trigger, the red beam of
light from the scanner does not turn
off.

If your CK31 contains an imager:
• If the CK31 is configured for continuous/edge

triggering, the red beam should remain on. This
is not a troubleshooting issue.
• If the CK31 is configured for level triggering

(default), the red beam should turn off. If the
red beam remains on, there may be a problem
with the scanner. Press the Scan button or pull
the trigger again without scanning a bar code
label. If the red beam is still on, contact your
local Intermec service representative.
If your CK31 contains a laser scanner:
• If you set the Aim then Scan parameter to

Enable and the Turn off after good read
parameter to Disable/Auto-Trigger, the red
beam should remain on. This is not a
troubleshooting issue.
• If those parameters are not configured, the red

beam should turn off. If the red beam remains
on, there may be a problem with the scanner.
Press the Scan button or pull the trigger again
without scanning a bar code label. If the red
beam is still on, contact your local Intermec
service representative.

CK31 Handheld Computer User’s Manual

121

Chapter 5 — Troubleshooting and Maintaining the CK31

Problems While Scanning Bar Codes (continued)
Problem

Solution

The scanner does not read the bar
code labels quickly, or the scanning
beam seems to be faint or obscured.

The scanner window may be dirty. Clean the
window with a solution of ammonia and water.
Wipe dry. Do not allow abrasive material to touch
the window.

You scan a valid bar code label to
enter data for your application. The
data decoded by the scan module
does not match the data encoded in
the bar code label.

Try these possible solutions in order:
• The computer may have decoded the bar code

label in a symbology other than the label’s
actual symbology. Try scanning the bar code
label again. Make sure you scan the entire label.
• To operate the computer quickly and

efficiently, you should enable only the bar code
symbologies that you are going to scan.
You receive an error when changing
the scanner model with a serial
adapter attached.

Try these steps in order:
1 Check to make sure the serial adapter is
attached to the CK31.
2 Disconnect and then reconnect the serial
adapter to the CK31. The green Good Read
light flashes to indicate that the software is
auto-detecting the adapter and loading the
software.
3 Warm boot the CK31.

You receive a message reading
“Scanner Communication Failure”
when trying to connect a 1551E or
1553 decoded scanner.

Try these possible solutions in order:
• Make sure that you are using the correct cable

(P/N 3-606034-xx).
• Try enabling the scanner port. Go to Data

Collection > Dock Tethered Scanner >
Enable scanner port.
• Try upgrading the scanner firmware.
• Select ASCII as the scanner model.

122

CK31 Handheld Computer User’s Manual

Chapter 5 — Troubleshooting and Maintaining the CK31

Problems While Scanning Bar Codes (continued)
Problem

Solution

Your 1551E or 1553 scanner
stopped working after you activated
energy saver mode or connected a
cable.

You can enable energy saver mode only if the
scanner is connected to the CK31 by the energy
saver cable P/N 3-606032-03. Follow these steps:
1 Disconnect the scanner from the CK31.
2 Find the Reset Factory Defaults bar code in the
scanner documentation.
3 While pulling the trigger, hold the scanner over
the Reset Factory Defaults bar code, and apply
external power to the scanner. The scanner is
reset to factory defaults.
4 Use Intermec Settings to disable energy saver
mode on the CK31.
5 Use Intermec Settings to disable the port.
6 Attach the scanner to the CK31.
7 Use Intermec Settings to enable the port.
8 Use the scanner to scan a bar code. The scanner
should work now, but energy saver mode is
disabled. Continue with Steps 9 through 11
only if you want to use energy saver mode.
9 Install the P/N 3-606032-03 energy saver cable.
10 Use Intermec Settings to enable energy saver
mode on the CK31.
11 Use the scanner to scan a bar code. Energy saver
mode is enabled.

CK31 Handheld Computer User’s Manual

123

Chapter 5 — Troubleshooting and Maintaining the CK31

Problems While Scanning Bar Codes (continued)
Problem
The scanner will not read the bar
code label.

Solution
• Make sure you aim the scanner beam so it
crosses the entire bar code label in one pass.
• The angle you are scanning the bar code label

may not be working well, or you may be
scanning the label “straight on.” Try scanning
the bar code label again, but vary the scanning
angle.
• The bar code label print quality may be poor or

unreadable. To check the quality of the bar
code label, try scanning a bar code label that
you know will scan. Compare the two bar code
labels to see if the bar code quality is too low.
You may need to replace the label that you
cannot scan.
• Make sure the bar code symbology you are

scanning is enabled. Use Intermec Settings to
check the symbologies. If your bar code
symbology is disabled, enable it and then try
scanning the bar code label again.
• Make sure that the application you are running

on the computer is expecting input from a bar
code. You may need to type this information
instead of scanning it.
• If you are using the 2D imager, set Lighting

Mode to Illum LED priority and set Lighting
Goal to 100 (or greater). Use Intermec Settings
to change the Lighting Mode setting.
• If the bar code is rotated, make sure that you

have 1D Omni-directional scanning enabled.
Use Intermec Settings to enable 1D Omnidirectional scanning.

Finding the Registry Entries for Keypad Changes
The CK31 provides registry files for each keypad change you
make. These files are located at:
\CK_FFS\KeypadMods\KeypadModxxxx.reg
Each modification has its own entry. To combine entries, copy
all the keys into a single registry file and combine identical keys
to contain the data from both files.
For example if one .reg file contains:
[HKEY_LOCAL_MACINE\HARDWARE\DEVICEMAP\KEYBD]
"ScancodeFilterArray"=hex:\
0a,00,00,00,04,00,00,00,00,00

And the other .reg contains:
[HKEY_LOCAL_MACINE\HARDWARE\DEVICEMAP\KEYBD]
"ScancodeFilterArray"=hex:\
11,00,01,00,03,00,00,00,00,00
"KeyFilterProcess0x111"="\Windows\cmd.exe"
"KeyFilterCmd0x111"="test"

Your combined reg file should look like this:
[HKEY_LOCAL_MACINE\HARDWARE\DEVICEMAP\KEYBD]
"ScancodeFilterArray"=hex:\
11,00,01,00,03,00,00,00,00,00,
0a,00,00,00,04,00,00,00,00,00

Creating Keypad Macros
A keypad macro is a sequence of keys mapped to a single key or
key combination. Keep the following considerations in mind
when programming with macros:
• You can only use one macro at a time.
• Do not use scan triggers in macros because they are timing
dependent.
• Avoid using key sequences that launch applications because of
timing issues.
• The best use of macros is as a tool for repetitive data entry.

Finding the Registry Entries for Keypad Macros
Registry files for each keypad macro are provided for you. These
files are located at:
\CK_FFS\KeypadMods\KeypadModxxxx.reg
Each macro has its own entry. To combine entries, copy all the
keys into a single registry file and combine identical keys to
contain the data from both files.
For example if one .reg file contains:
[HKEY_LOCAL_MACINE\HARDWARE\DEVICEMAP\KEYBD]
"ScancodeFilterArray"=hex:\
08,00,0d,00,06,00,06,00,00,00
"KeyMacro0xd08"=hex:\
08,00,00,00,00,00,00,00,\
08,f0,00,00,7a,00,00,00,\
10,00,00,00,19,00,00,00,\
10,f0,00,00,01,00,00,00,\
18,00,00,00,19,00,00,00,\
18,f0,00,00,6e,00,00,00

And the other .reg contains:
[HKEY_LOCAL_MACINE\HARDWARE\DEVICEMAP\KEYBD]
"ScancodeFilterArray"=hex:\
0d,00,05,00,06,00,06,00,00,00
"KeyMacro0x50d"=hex:\
0a,00,00,00,00,00,00,00,\
0a,f0,00,00,a0,00,00,00,\
11,00,00,00,19,00,00,00,\
11,f0,00,00,6c,00,00,00,\
19,00,00,00,19,00,00,00,\
19,f0,00,00,6b,00,00,00

Your combined reg file should look like this:
"ScancodeFilterArray"=hex:\
08,00,0d,00,06,00,06,00,00,00,
0d,00,05,00,06,00,06,00,00,00
"KeyMacro0xd08"=hex:\
08,00,00,00,00,00,00,00,\
08,f0,00,00,7a,00,00,00,\
10,00,00,00,19,00,00,00,\
10,f0,00,00,01,00,00,00,\
