'I had to replace the battery on my Mk 2 Jazz and consequently re-enter the security code but I am unable to enter the code.
The code is shown as a sequence of 6 numbers and below a sequence of 3 letters followed by 8 numbers . the station
numbers 4, 5 and 6 have letters below them. However when I try to enter the code the display simply says enter the security code. I am at a loss as to where to proceed from here.
Any help will be much appreciated.
