DESS KEY PROGRAMMING
The Vehicle Communication Kit (VCK) (P/N 529
035 981) is the primary tool to program a DESS
key.
The software B.U.D.S., included in the VCK, is de-
signed to allow, among other things, the program-
ming of safety lanyard(s) and entering customer
information.
For more information pertaining to the use of the
software B.U.D.S., use its help which contains de-
tailed information on its functions.
WARNING
If the computer you are using is connected
to the 110 Vac power outlet, there is a poten-
tial risk of electrocution when working in con-
tact with water. Be careful not to touch water
while working with the VCK.
