(See "Base Charge Mode" on page 1-5)• The battery is not bad or deeply discharged. In some cases, the scanner’sbattery may trickle charge to bring it into an acceptable level and thentransition to a normal charge cycle.Troubleshooting ScannerNote: Make sure that your scanner’s battery is charged.Note: Please visit the Services and Support section of our website(www.handheld.com) to check for the latest software for both the scannerand the base.Is the scanner having trouble reading your symbols?If the scanner isn’t reading symbols well, check that the symbols:• Aren’t smeared, rough, scratched, or exhibiting voids.• Aren’t coated with frost or water droplets on the surface.• Are enabled in the base to which the scanner connects.Is the bar code displayed but not entered into the application?The bar code is displayed on the host device correctly, but you still have to pressa key to enter it (the Enter/Return key or the Tab key, for example).You need to program a suffix. Programming a suffix enables the scanner tooutput the bar code data plus the key you need (such as “CR”) to enter the datainto your application. Refer to Prefix/Suffix Overview on page 4-1 for furtherinformation.Does the scanner read the bar code incorrectly?If the scanner reads a bar code, but the data is not displayed correctly on the hostscreen:• The base may not be programmed for the appropriate terminal interface.For example, you scan “12345” and the host displays “@es%.”Reprogram the base with the correct Plug and Play or Terminal selection barcode. See Chapter 1 and Chapter 2.• The base may not be programmed to output your bar code data properly.For example, you scan “12345” and the host displays “A12345B.”Reprogram the base with the proper symbology selections. See Chapter 6.The scanner won’t read your bar code at all.2020/3820 User’s Guide 12 - 3
