First select Automatic tuning mode from Select mode (refer to section 2). 
Press    to scroll through the modes, then press      or    to set the required value.  
To exit from Automatic tuning mode, hold down    and press     to return to Select mode.  
Pre-tune is a single-shot routine and is thus self-disengaging when complete. 
If 136  in Setup mode = ;-1<, Pre-tune will attempt to run at every power up*.

pressing the    key while in Operator mode, or by changing the status of the digital input if 
4050 has been configured for 401? in Configuration mode. The      indicator will flash 
while in Manual Control mode and the lower display will show 3xxx (where xxx is the current 
manual power level). Switching to/from manual mode is via Bumpless Transfer. 
Press     or     to set the required output power. Caution: Not restricted by !32' limit.
