Just received my new BCD436HP scanner the other day and made a mistake with Sentinel software, I use one instance of Sentinel for both the SDS100 and The 436HP I wanted to send information to my SDS100 scanner and and did not have the target set to the SDS100 the target was set to the 4436hp, anyway as you know there is no button to lock you keypad for the sds100 scanner and I sent the profile for the 436hp to the sds100 and it locked the keypad on the sds100. In the top right hand corner of the screen there was a key showing the keyboard was locked could not do a thing with the sds100, but thankfully I did not brick it and just reset the scanner and deleted everything and sent the right info to the sds100. and it works perfect.
