Warrington Hand-Held Computer User Manual 201
• Hold the scanner closer for bar codes with bars that are close together.
A bar code icon appears on the screen during a scan. While the scanner beam is active, the
onscreen message states: SCANNING. If you want to turn off the onscreen message, disable
Scan Indication in the Options tab of the Scanner Settings menu in the Control Panel.
When the scan is successful, the bar code data is displayed on the screen until the scan
button (or pistol trigger) is released, but only if Scan Result is turned on in the Options tab
of the Scanner Settings menu in the Control Panel.
7.10.2 Troubleshooting
If the scanner is not working, investigate the following:
• Is the unit on?
• Check that the bar code symbology being scanned is enabled for the hand-held you are
using. Check any other parameters that affect the scanning procedure or the bar code.
• Check the bar code to make sure it is not damaged. Try scanning a different bar code to
verify that the problem is not with the bar code.
• Check that the bar code is within the proper range.
• Does the hand-held display the warning without scanning? This suggests a hardware
problem in the hand-held.
• Is the laser beam scanning across the bar code?
• Once the scan beam has stopped, check the scanner window for dirt or fogging.
7.10.3 Operating One Dimensional (1D) Laser Scanners
• Turn the hand-held on. Wait until the unit has booted up completely.
• Aim at the bar code and press the scan key or the trigger. A scan beam and a warning
indicator appear until a successful decode is achieved or six seconds have elapsed.
Important: If an aiming dot is available on the installed scanner, the dot will be enabled
for a configurable time period (including off), after which normal scanning
begins. Refer to “Dot Time (msec)” on page 137 for details.
Double-clicking the trigger will override the aiming delay and initiate an
immediate scan. Note that the aiming dot is standard on long-range and
high visibility internal scanners.
