LifeFitness 9000 treadmill - how to change max running time ?



Hello !

I have one question, maybe you could help me. I bought a used
LifeFitness 9000 Treadmill and I'm very happy with it.
I can only run 30 minutes because it is so programmed and
I don't know what keys I have to press/hold to enter the maintanence
setup to change the maximum running time because I have no manual.
Maybe you could tell me just what keys to hold to enter the menue. I
would be very very happy and thankful if you maybe could help me with
my
problem...

In anyway, Best Wishes,
Tim Schmidt
