If an error is detected, the scanner will sound a long low tone (for three
seconds) and alternately flash its LEDs, indicating a failure. When this
occurs, press the Volume/Tone Push button to display the error code on
the 7-segment display (refer to Figure 4-1). If it is configured to do so, the
scanner will also sound a series of beeps corresponding to the error code.
The table below describes what these codes mean and what action should
be taken for each.
When troubleshooting, always remember to check all cable connections
first before proceeding with other problem isolation steps.
