Cradle-less, Connection (MS840B)
 
Cradle-less Mode (without SCM support) 
MS840 can connect directly to a Host with proper supported wireless technology. In 
order to establish a proper connection between your Host with wireless technology 
and the scanner, we suggest that you follow these step-by-step instructions: 
1.  Turn on your Host.   
2.  Change the default cradle-mode to the cradle-less mode by scanning the 
Cradle-less Mode barcode.

4.  Make your Host with wireless technology search for the MS840 scanner. When 
your Host locates a “HID SCANNER”, select it. 
5.  The Host should now present a pairing pin and you will be requested to input the 
pin code at the Scanner. For inputting the pin code, scan the “Link Keys” barcode 
below:

6.  At this step, referring to the barcode table below, scan the pin code one after 
another you got from your PC; for example, if you get the pin code “241657”, then 
scan the barcodes “2” – “4” – “1” – “6” – “5” – “7” listed in the table in the order.
