The protective cover over the "FCC ID" label on the back of my SDS100 has started to come off. As a result, the printing on the label has started to dissolve and the area around the label is quite sticky. I'm thinking that this is due in part from heat generated by the scanner as well as heat from my hand during repeated hand-programming and hand-held operations. Anyone else have this problem? Are replacement labels or back covers w/attached labels available? Thanks in advance!
