Thanks for your reply
The problem is small really but it bugs me not being able to to do anything about it
The thing is one of the faults that comes up is that the rear near side is out of range(up or down) I cannot remember the exact words but it all means the same
As you say I believe the Hawkeye will not let you calibrate but it does give the impression that it will
I have gone on to do the calibration but it comes up as are you qualified to do this , with that I back down as I am afraid of doing something I cannot correct, bit of a coward as it were
Thanks if someone knows if it is possible to use the hawkeye
