Before You Begin

Who Should Read This Document?

The CK31 Handheld Computer User’s Manual provides you with information about the features of the CK31 and how to install, operate, maintain, and troubleshoot the CK31. Before you install and configure the CK31, you should be familiar with your network and general networking terms, such as IP address.

The Intermec Computer Command Reference Manual (P/N

073529) is available on the CD attached to the inside front cover of this user’s manual and as a download from the Intermec web site. Please refer to this manual for help configuring your CK31. The reference manual contains information about all of the CK31 commands and provides bar codes that you can print and scan when configuring supported commands.

Introducing the CK31 Handheld Computer

The Intermec CK31 is an ergonomically designed handheld computer built on the Microsoft

Windows® CE .NET operating system. It is a lightweight, easy-to-use, reliable computer that both runs client/server applications and browserbased applications.

CK31 Handheld Computer User’s Manual 3

Chapter 1 — Using the CK31 Handheld Computer

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 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.

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.

4 CK31 Handheld Computer User’s Manual

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.

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.

CK31 Handheld Computer User’s Manual 5

Chapter 1 — Using the CK31 Handheld Computer

To install the battery

• Insert the tabs on the bottom of the charged battery into the

CK31 and snap the battery into place.

Inserting the AB1G Battery

Maximizing Battery Life

Battery latch

AB1G battery

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.

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

Using the Keypad

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.

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 7

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 Terminal Emulation Programmer’s Guide (P/N 977-055-xxx).

Note: The 50-key keypad does not have a scan key, because it was designed to work with the required handle with the built-in scanner trigger.

Using the Color-Coded Keys

The keypad of the CK31 provides color-coded keys to let you access additional characters, symbols, and functions printed on the keypad overlay. Once you understand how to use the color-coded keys and key sequences, you can access all of the additional features printed on the keypad overlay. There are two color-coded modifier keys on the CK31: the orange B key and the green C key.

Chapter 1 — Using the CK31 Handheld Computer

To disable Caps Lock

• Press the orange B key and then press either Shift or A

(depending on your keypad). The Caps Lock icon disappears from the status bar.

Using the Power (I) Key

When you press the I key to turn off the CK31, you actually put the computer in Suspend mode. In Suspend mode, the CK31 continues to supply power to all memory, but turns off power to most hardware. This power-saving feature is designed to prolong battery life.

When you press the I key to turn the CK31 back on, your computer resumes at the screen that was displayed when you turned it off. If you are using WPA or 802.1x security, the computer may need to reauthenticate before it resumes your application.

If the Battery light flashes and your CK31 does not resume after pressing I, your battery may be too low to supply power. Replace the battery. If replacing the battery does not solve the problem, see “Booting the CK31” on page 125.

Disabling or Modifying Keypad Functions

If you want to restrict the ability to perform adjustments made from the keypad, such as changing the beeper volume, you can disable the functionality of several keys on the keypad.
