Introducing the CN50 Mobile Computer
The Intermec CN50 Mobile Computer is a small, sleek, and stylish
mobile computer built on the Microsoft®Windows®Mobile 6.1
operating system. The CN50 uses dual ARM processors to provide
high throughput and is the only mobile computer with the latest
High Speed Uplink Packet Access (HSUPA). The CN50 is also the only
mobile computer that can be reprovisioned from a CDMA to a GSM/
UMTS network.
CN50 Mobile Computer
Here are more great features of the CN50:
•A digital compass to enhance GPS navigation and improve
geotagging of captured images.
•An accelerometer that can automatically rotate the display
between portrait, landscape and upside-down viewing.
•The highest quality color camera in a mobile computer.
•An area imager that supports reading bar codes, signature capture,
and Enhanced Mobile Document Imaging (eMDI).
The CN50 Mobile Computer with an IEEE 802.11b/g radio
installed is Wi-Fi®certified for interoperability with other
802.11b/g wireless LAN devices.

Use this manual to understand how to use the CN50 and other
features and options available on it. For information about Windows
Mobile 6.1 applications installed on the CN50, refer to the online
help.
Using the Battery
The CN50 uses an AB24 standard or AB25 extended battery as its
main power source. The standard battery has a 7.2 Watt hour capacity,
and the extended battery has a 14.4 Watt hour capacity. Several
factors determine the life of your battery, such as extreme
temperatures, input devices, and your usage.
You must fully charge the battery before you can use the CN50. When
you change the battery, an internal super capacitor maintains your
status, memory, and real-time clock for approximately 5 minutes.
For replacement batteries, contact your Intermec representative.
Charging the Battery
Make sure you fully charge the AB24 or AB25 battery before you use
your CN50. You can charge the battery before or after you install it in
the CN50. A fully discharged battery charges in approximately 4
(AB24) to 6 (AB25) hours.
To charge the battery
•Insert up to four batteries into the AC21 quad battery charger.
The battery 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 batteries
promptly. Keep away from children.
If you fail to replace the low battery immediately, you may lose
important data or applications.
Note: If the CN50 is not using external power and you remove the
battery pack, the CN50 goes into Suspend mode.

•Install the battery in the CN50 and insert the CN50 into the AD23
charge-only multidock or AD24 Ethernet multidock.
•Attach an AE37 AC adapter or AE36 vehicle battery adapter.
Use the next table to understand how long it takes to charge your
batteries in each of the CN50 charger or dock accessories.
Removing and Installing the Battery
To maximize the time allowed to replace the main battery pack, put
the CN50 in suspend mode before removing the battery pack.
To remove and install the battery
1Press and hold £for about 2 seconds. When you release £, the
CN50 goes into suspend mode.
2If necessary, disconnect the handstrap from the top of the CN50.
Charging Times for CN50 Batteries
CN50 Charging Accessory AB24 Charging Time AB25 Charging Time

AD23 charge-only multidock 4 hours 6 hours
AD24 Ethernet multidock 4 hours 6 hours
AE36 Vehicle battery adapter 4 hours 6 hours
AE37 AC adapter 4 hours 6 hours

3Push forward on the battery release tab until the battery releases,
and then lift it away from the CN50.
4Insert a fully charged battery into the CN50, and press down on
the battery until it clicks into place.
5If necessary, replace the handstrap.
Maximizing Battery Life
Batteries are chemical devices. If the batteries are left sitting on a shelf
for long periods of time outside the CN50, the batteries slowly
discharge, eventually to zero if left uncharged. The battery chemistry
resists normal degradation if you store the battery in a charger as
opposed to leaving the battery in a discharged state. See the following
table for tips to maximize the life of your battery.
Battery Conservation Tips
When You Want To: Do This to Save Battery Power:

Checking the Battery Status
The easiest way to check the status of your battery is to look at the
battery icon on the status bar of your CN50.
Store the CN50 for more
than a day.
If you are storing the CN50 for a few days, like
over the weekend, install the charged battery
or attach the CN50 to a power source.
If you are storing the CN50 for longer, remove
and charge the battery, then store both the
battery and the CN50 in a cool location.
If the battery in storage is not used in several
months, you should recharge the battery to
keep it at its performance peak.
Store the battery outside the
CN50.
Store the batteries in a charger.

charging status of your battery.
Using the Keypad
Use the following sections to understand how to use the keypad. For
information on remapping the keypad, you can download the Device
IDL Resource Kit from the Intermec web site at www.intermec.com/
idl.
The CN50 comes with a numeric keypad or a QWERTY keypad. The
QWERTY keypad is designed for applications that require primary
input of alphabetic data. This keypad also provides special characters,
numbers, symbols, and functions by pressing color-coded key
sequences.
The numeric keypad is for applications that require mainly numeric
data. This keypad also lets you enter special characters, including the
alphabet, by pressing color-coded key sequences.
