4 Troubleshooting and Maintaining the CN2G Use this chapter to solve problems you may encounter while using the CN2G. You will also find information on booting the computer and routine maintenance.
Chapter 4 — Troubleshooting and Maintaining the CN2G Problems and Solutions If you send the CN2G in for service, it is your responsibility to save the computer data and configuration. Intermec is responsible only for ensuring that the keypad and other hardware features match the original configuration when repairing or replacing your computer. Problems While Operating the CN2G Problem Solution You press the Power key to turn on the CN2G and nothing happens.
Chapter 4 — Troubleshooting and Maintaining the CN2G Problems While Operating the CN2G (continued) Problem Solution You place the CN2G in the communications dock, and the Battery light turns on and is orange. • The temperature may not be within the charging The CN2G appears to be locked up and you cannot enter data. Try these possible solutions in order: range. Make sure that the temperature is from 0°C to 45°C (32°F to 113°F). • The battery may be damaged. Replace the battery.
Chapter 4 — Troubleshooting and Maintaining the CN2G Problems While Configuring Security (continued) Problem Solution The CN2G does not appear to be authenticating and a network connection icon does not appear on the status bar. To see a list of network connections icons, see “Understanding the Screen Icons” on page 13. The CN2G may not be communicating with your access point.
Chapter 4 — Troubleshooting and Maintaining the CN2G Problems While Configuring Security (continued) Problem Solution You receive a message saying, “The server certificate has expired or your system date is incorrect” after you cold boot the CN2G. The date and time on the CN2G are not saved through a cold boot. You need to re-enter the date and time and then save your changes. You are setting up multiple access points in a network, with different SSIDs, and the connection fails.
Chapter 4 — Troubleshooting and Maintaining the CN2G Problems With Wireless Connectivity (continued) Problem Solution The no network connection icon ( ) appears on the status bar. The no network icon appears in three situations: • The CN2G may not have an IP address. You must configure an IP address for the CN2G or make sure that DHCP assigned an address. Use Intermec Settings and select the radio tab to make sure an IP address has been assigned.
Chapter 4 — Troubleshooting and Maintaining the CN2G Problems While Scanning Bar Codes Problem Solution You cannot see a red beam of light from the scanner when you press the Scan button or one of the Side Scan buttons and aim the scanner at a bar code label. There are three possible problems: • 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.
Chapter 4 — Troubleshooting and Maintaining the CN2G Problems While Scanning Bar Codes (continued) Problem Solution The scanner will not read the bar code label (continued). Make sure the bar code symbology you are scanning is enabled. Use Intermec Settings to check the symbologies. If your bar code symbology is disabled, enable it and then try scanning the bar code label again. Make sure that the application you are running on the computer is expecting input from a bar code.
Chapter 4 — Troubleshooting and Maintaining the CN2G Booting the CN2G You seldom need to warm or cold boot the CN2G. The CN2G uses the configuration currently saved in flash memory during the boot process. You need to boot the CN2G when an application is locked up and will not respond, when you upgrade the firmware, or when you reflash the computer. The next instructions explain how you warm and cold boot the CN2G.
Chapter 4 — Troubleshooting and Maintaining the CN2G To warm boot the CN2G using the Power key 1 Press and hold the Power key for approximately 10 seconds. Note: After about 5 seconds, the backlight toggles. Keep holding the Power key for another 5 seconds until the backlight flashes. 2 Release the Power key.
