I got the DTT
- The left most button sets the display and also function mode eg. set it to a fixed time, auto timer, boost gauge display etc etc
- When u set the mode to auto timer, u can press one of the 2 buttons on the right to set the mode of the auto timer:
either Boost - Low, Med, Hi
OR Time - Low, Med, Hi
Also, when u press the other of the 2 buttons it should set the minimum amount of time for the auto timer (i set it at 50 sec)
Hope it helps. I just have the jap manual, but I was fiddling for a while and worked it out. I think you need to fix your sensor if you are getting half the speed display on the FATT. Good luck
