Does Your CN2 Contain an 802.11b/g Radio?
How to Determine Description In This Manual
Look at the Configuration
Number (CN) on the label inside
the battery compartment. For
help removing the battery door

which can communicate in
a wireless network.
For details about wireless
communications, see
“Configuring 802.11b/g
Radio Communications”
on page 47.
If the CN ends in 000, your CN2
does not contain a radio. For
example, CN2A11E10N2000.

which requires a modem
dock or communications
dock to communicate with
a network.
For details about batch
communications, see
“Configuring USB
Communications” on
page 46.

Chapter 1 — Using the CN2 Handheld Computer
CN2 Handheld Computer User’s Manual 5
Using the Battery
The CN2 uses a lithium-ion battery as its main power source.
You must fully charge the main battery before you can use the
CN2.
While you change the battery, the backup battery maintains the
computer’s status, memory, and real-time clock for at least 5
minutes.
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 de 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.
Warnung: Der Lithiumionen-Akku, der in diesem Gerät
verwendet wird, kann eine Brandgefahr oder chemische
Brandgefahr darstellen, falls ee missbräuchlich verwendet
wird. Nicht zerlegen, über 100°C (212°F) erwärmen oder
verbrennen.
Removing the main battery when the backup battery low or
critically low icon appears on the status bar may cause your
CN2 to cold boot and you may lose data.
Attention: Si vous enlevez la batterie principale quand
l’icône de batterie de secours dans la barre de statut indique
bas ou bas critique, cela peut causer une botte froide à votre
CN2 et vous risquez de perdre des données.
Vorsicht: Das Entfernen des Hauptakkus bei schwacher
Reservebatterie oder wenn das Symbol für „leeren Akku“ in
der Statusleiste eingeblendet ist, kann einen Kaltstart des
Modells CN2 auslösen und zu Datenverlusten führen.

Chapter 1 — Using the CN2 Handheld Computer

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.
Vorsicht: Falls der Akku nicht unverzüglich ausgetauscht
wird, können importierte Daten oder Anwendungen
verloren gehen.
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 and your usage.

4Lift the battery out of the battery compartment.
Maximizing Battery Life
There are several things that you can do to maximize the life of
your fully charged battery.
•Set the Backlight Timeout to 10 seconds.
•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.
•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 CN2
Locally With Intermec Settings” on page 36.
Checking the Battery Status
The easiest way to tell the status of your battery is to look at the
battery icon on the taskbar of your CN2. For help locating the
taskbar, see the illustration on page 15.

Understanding the Desktop
The Start screen has two distinct areas: the desktop and the
taskbar. The desktop displays shortcuts to some of the
applications installed on the CN2. The first time you turn on
the CN2, the taskbar displays the Start menu icon, the time, the
keyboard icon, and the desktop icon.
Most of the default shortcuts on the desktop are standard
Windows CE applications. However, Intermec provides
shortcuts to two additional applications:
•ScanDemo is a simple application you can use to verify that
your imager is working correctly. (This application is installed
only if your CN2 has a scanner.)
•Transcriber enables you to write on the screen with your
stylus, and then it converts your writing to text.
Using ScanDemo
ScanDemo is an application that enables the CN2 to read bar
code labels and display the information encoded on the label
along with the symbology used to encode it.
To open ScanDemo
1Double-tap the ScanDemo shortcut on the desktop. The
ScanDemo application opens.
2Scan a bar code label. For information on how to scan a bar
code label, see “Scanning Bar Codes” on page 25. The
