Problems and Solutions

Problem: Scanner doesn’t light up.

If the scanner does not emit a light when the trigger is pressed, make sure the scanner is switched on (see page 5), and/or that the battery is charged (see page 8).

Problem: Scanner lights up but doesn’t beep.

If the scanner emits a light, but doesn’t beep when scanning a bar code, try bar codes of different symbolo- gies. If other types of bar codes scan properly, then it might be that the scanner is not configured to scan your particular symbology.

If the scanner can scan other bar codes of the same symbology, then other parameters (such as minimum/ maximum length, etc.) may have to be adjusted.

Insure that your bar code has been created properly, with crisp edges and start/stop sentinels. For instance, Code 39 bar codes require asterisk (*) start/stop sentinels at the beginning and end of the data string (*123ABC*).

Avoid glossy surfaces or glossy inks for your bar codes. A glossy black surface may be indistinguishable from a white surface to your scanner because of the reflected light. Try photocopying your bar code and scanning the copy to determine if glossiness may be a factor.

Problem: Scanner makes four high-low beeps when at- tempting to scan.

The scanner has not been properly configured. A full reset is required by scanning the “Factory Default” bar code (see page 62), and switching the scanner off and back on again (see page 2, item 4).
