Frequently Asked Questions - SL220 Unitech
How do I connect the Unitech SL220 scanner to my computer?
Simply plug the USB cable into an available USB port. The scanner will be recognized as a HID keyboard device. No additional drivers are required for basic barcode input.
What should I do if the scanner is not reading barcodes?
First, ensure the barcode is clean and undamaged. Check the scanner's connection and try scanning a test barcode from the manual. If it still fails, reset the scanner by unplugging it for 10 seconds.
How do I clean my Unitech SL220?
Use a soft, lint-free cloth slightly dampened with water or a mild cleaning solution. Avoid abrasive materials or spraying liquid directly onto the scanner. Dry thoroughly before use.

How do I adjust the beep volume?
Scan the configuration barcodes provided in the manual. There are barcodes to increase, decrease, or mute the beeper volume completely.
