Programming cable
Insert the program-
ing cable with the
flex strip contacts
away from the bat-
tery door.
Connect the flex into
the shell by using the flex
end marked with an arrow.
To ensure good contact during programming and testing, be
sure to insert the programming strip at a 90oangle to the
programming springs. Inserting it at a slanting angle might
cause bad or intermittent contact that will cause failures
during programming. This is important both during FONIX
device calibration/test and when programming on Aventa.
