Chapter 3: Getting To Know Your 7530 G2
Scan LED Indicators
50 Psion Teklogix 7530 G2 Hand-Held Computer User Manual
3.6.2 Scan LED Indicators
The scanner LED (the lower-left LED) indicates whether or not your scan is
successful. The LED behaves as follows:
• Scan In Progress: scan LED displays solid red colour.
• Successful Scan: scan LED displays solid green colour and turns off when
the scan is ended.
• Unsuccessful scan: scan LED flashes red.
A bar code icon appears on the screen during a scan. While the scanner beam
is active, the onscreen message states – SCANNING. If the scan is successful,
the bar code data is displayed on the screen until the scan button (or pistol trigger)
is released.
3.6.3 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 scan-
ning 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.
3.6.4 Operating One Dimensional (1D) Internal Laser Scanners
• Turn the hand-held on. Wait until the unit has booted up completely.
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 146 for details.
