3.8.3 Troubleshooting
If the scanner is not working, investigate the following:
•
Is the 8515 on?
• Check that the scanner settings are correctly configured (see “Scanner Settings” on page
109 ).
• 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 vehicle-mount display the warning without scanning? This suggests a hard-
ware problem in the 8515.
• Is the laser beam scanning across the bar code?
• Once the scan beam has stopped, check the scanner window for dirt or fogging.
3.8.4 Operating One Dimensional (1D) Laser Scanners
• Turn the 8515 on. Wait until the unit has booted up completely.
• Aim at the bar code and press the trigger. A scan beam and a warning indicator appear
until a successful decode is achieved or six seconds have elapsed.
3.8.5 Operating PDF Laser Scanners
This scanner decodes PDF417 two-dimensional bar codes.
•
Turn the vehicle-mount on. Wait until the unit has booted up completely.
• Aim at the bar code and press the trigger. The beam expands into a rectangle covering
the bar code to properly scan it. The scan beam and a warning indicator are visible until
a successful decode is achieved or three seconds have elapsed.
3.9 Monitoring The Network Connection
If your vehicle-mount is equipped with a wireless LAN radio, it will typically associate with
the nearest access point. The radio signal quality meter in the taskbar indicates the relative
strength of the communication link. To access the radio signal icon from the keyboard:
•
Tap on the radio icon in the taskbar to display the Wireless Statistics dialog box.
Note: Moving in and out of the radio coverage area can have varying effects on a
network session. At times, you may need to renew your connection by logging
in again.
