Frequently asked questions

Can the HD6600 work without being paired to a device?

Yes. Thanks to its built-in memory, the HD6600 can store up to 5000 scanned codes offline and transfer them to a computer later, which makes it ideal for mobile inventory and fieldwork.

What is the difference between 2.4 GHz and Bluetooth mode?

The 2.4 GHz mode uses the included USB receiver and works as a plug-and-play wireless keyboard with computers. Bluetooth mode allows pairing directly with smartphones, tablets and laptops without any receiver.

Which code symbologies does the HD6600 read?

The HD6600 reads all leading 1D barcodes (including Code 128, Code 39, EAN/UPC, ITF, GS1 DataBar) and 2D codes such as QR Code, Micro QR, Data Matrix, PDF417 and Maxicode.

How do I configure the HD6600?

All settings are changed by scanning the QR configuration codes on this page — e.g. keyboard layout, terminator, prefixes/suffixes or per-symbology switches. If anything goes wrong, scan the Restore factory defaults code.

Can I add a function key (e.g. F1) as a prefix or suffix?

Yes. Scan the Set multiple prefixes or suffixes code, then four numeric codes with the key's scan value from the character equivalents table (e.g. F1 = 1022), and finish with the Complete setup code.
