What If...
Nothing happens when you follow the operating
instructions?
You Should
•
Check that the power supply is attached to the base station.
•
Check for loose cable connections at the base station and host device.
•
Check the scanner’s battery pack.
•
Make sure the device is programmed to read the type of bar code you
want to scan.
•
Check the symbol to make sure it is not defaced.
•
Try scanning similar symbols of the same code type.
•
Check that the “gas tank” is not exhausted.* Wait a few seconds, then try
scanning. If the scanner works, allow sufficient time for the gas tank to fill
before returning to normal usage.
•
Make sure the scanner and base station have been successfully paired.
•
Be sure you’re within the proper scanning and transmission range.
* The gas tank limits the amount of time the laser remains on within a given period
to conform to the requirements of IEC 825 Class 1.
The base emits transmit errors (error beeps after decode).
You Should
•
Check that the base station is powered up and that its cable connections
are secure.
•
Be sure the cable connection to the host is secure.
•
Check that the appropriate host type is selected.
