• UT-109 and UT-110 scrambler units require some PC
board modifications. (See below and next.)
• IC-F30/F31GT/GS, IC-F40/F41GT/GS series require
a #02: High AF level type scrambler unit. Do not in-
stall the wrong version, as they are not compatible.
• The UT-110 may function as the UT-109 through
cloning software.
• Compatible cloning software: CS-F30G.
