Upgrading the Operating System on your Computer
You can use the SmartSystems™ Foundation application from Intermec to
perform upgrades on your CN3, versions 3.0 or later. Contact your
Intermec representative for more information about the SmartSystems
Foundation software.
When you upgrade the operating system, you erase the current
configuration and replace it with the new default configuration. You will
need to reset the network parameters on the CN3 to reestablish
communications with other devices in the network. In other words, if you
upgrade the operating system and the default registry from the operating
system has changed, the registry is rolled back to the new default.
When you upgrade your CN3, you are updating the operating system (OS)
and the SmartSystems Platform Bundle (SSPB) files.
The SSPB files are stored on the DiskOnChip, and deliver Intermec value-
added functionality such as data collection, unit configuration and
diagnostics, and Intermec’s wireless security suite. As new features are added
to these components, you can upgrade your SSPB files without needing to
upgrade the operating system image. Similarly, features added to the
operating system images do not affect the functionality of the SSPB, and
you can choose to upgrade only the operating system image.
There are two ways to upgrade the CN3:
• You can use a miniSD card to upgrade the CN3. For help, see the next
page.
• You can use the SmartSystems Console to upgrade the CN3. For help,
see “Using the SmartSystems Console to Upgrade the Computer” on
page 98.
You need to download the latest upgrade files from the Intermec web site to
your desktop or laptop computer, then determine if you want to upgrade
both the operating system and SSPB files, just the operating system files, or
just the SSPB files.
To download the latest upgrade files
1Start your web browser and go to the Intermec web site at
www.intermec.com.
2Go to Service & Support > Downloads.
3Select Computers: CN3 Mobile Computer from the drop-down list.
4Select which download you need. Make sure the download you select is
for the CN3.
5Look at the description (or the ReadMe file) to determine if this
download will upgrade both the operating system and SSPB files, just the
operating system, or just the SSPB. You will need this information later.

these problems and possible solutions.
Problems with Wireless Connectivity
Problem Solution
When you turn on the CN3 after
it was suspended for a while (10-
15 minutes or longer), it can no
longer send or receive messages
over the network.
Host may have deactivated or lost current terminal emulation session. In a
TCP/IP direct connect network, turn off the “KeepAlive” message from host to
maintain the TCP session while a CN3 is suspended.
The No Network Connection
icon appears on the toolbar. The
CN3 is not communicating with
the access point.
The CN3 is not connected to access point. Ensure access point is turned on and
operating. Move closer to access point to reestablish communications. Ensure the
CN3 is configured correctly for network. CN3 radio parameters must match all
access point values.
If you have an 802.11b/g radio and its radio initialization process failed, reset the
CN3 (see page 5).
If No Network Connection icon still appears, you may have a defective radio
card. For help, contact your local Intermec representative.
The CN3 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 is now replaced with
the No Network Connection
icon.
Move closer to an access point or to a different location to reestablish
communications until the Network Connection icon appears. Any data you
collected while out of range is transmitted over the network.
The Network Connection icon is
in the toolbar, but you cannot
establish a terminal emulation
session with the host computer.
There may be a problem with the host computer, with the connection between
the Intermec Application Server and the host computer, or with the connection
between the access point and the host computer. Check with network
administrator to make sure the host is running and allowing users to login to the
system.
The Network Connection icon is
in the toolbar, but the host
computer is not receiving any data
from the CN3.
In a UDP Plus network, there may be a problem with the connection between
the Intermec Application Server and the host computer. Check with 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 network administrator or use
your access point user’s manual.
Problems While Configuring 802.1x Security
Problem Solution
The CN3 indicates that it is
authenticated, but it does not
communicate with the host.
Make sure the CN3 IP address, host IP address, subnet mask, default router are
configured for network.
The CN3 does not appear to be
authenticating and a network
connection icon does not appear
on the toolbar.
The CN3 may not be communicating with access point. Make sure the CN3
network name matches access point network name (SSID).

the Scan button and aim the
scanner at a bar code label.
You may be too far away from the bar code label. Try moving closer to the bar
code label and scan it again.
You may be scanning the bar code label “straight on.” Change the scanning angle
and try again.
Move within 2 feet of a wall to test the effective scan of the scanner. For help
scanning bar codes, see page 15.
When you release the Scan button
or handle trigger, the Good Read
light does not turn off.
The Good Read light will remain on if you configure the CN3 to use
continuous/edge triggering. If you configure the CN3 for level triggering and the

Cleaning the Scanner and Camera Windows and Screen
To keep the CN3 in good working order, you may need to clean the EA11
scanner and color camera windows and the screen.
Clean the scanner and camera windows and screen as often as needed for
the environment in which you are using the CN3. To clean the CN3, use a
solution of ammonia and water.
The input device attached to the
CN3 does not work well or read
bar code labels very quickly.
Set the Scanner Model command to the specific attached input device. Check
enabled bar code symbologies and enable only the symbologies being used.
The scanner will not read the bar
code label.
Aim the scanner beam to cross entire bar code label in one pass. Vary the
scanning angle.
Check the quality of the bar code label, Scan 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.
Ensure the bar code symbology is enabled. Use Intermec Settings to check the
symbologies. Expand Data Collection > Symbologies beneath devices listed
(scanner, virtual wedge) to check and enable symbologies, then scan the bar code
label again.
Ensure the CN3 application is expecting input from a bar code. You may need to
type this information instead.
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.
The CN3 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.
There are no user-serviceable parts in the CN3. Opening the CN3 will
void the warranty and may cause damage to the internal components.
