CN3 Mobile Computer User’s Manual 994Maintaining the ComputerUse this chapter to solve problems you may encounter and perform routine maintenance on your CN3 Mobile Computer.
Chapter 4 — Maintaining the Computer100 CN3 Mobile Computer User’s ManualUpgrading the Operating System on your ComputerYou 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 files1Start 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.

Chapter 4 — Maintaining the Computer106 CN3 Mobile Computer User’s ManualCleaning the Scanner and Camera Windows and ScreenTo 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.Problems While Scanning Bar Codes (continued)Problem Solution
