Symbol LS4278 handheld barcode scanners losing settings



New Member
We have four of these barcode scanners. Two work fine but those two are used at stations where the user is active all day, every day. The other two stations are used more as backup. These two stations lose the settings/programming for the barcode scanner nightly. Meaning...I can reprogram the barcode scanner, user logs on, it works fine. Next day...all settings are lost. I've searched the net for help but can't find anything. By chance I thought maybe someone here may have experienced something similar or can give me hints on things to check with the pcs themselves.

Win7 pcs, users do not have admin rights but I do.

Thanks in advance.
