Multi-function Knob 
 
 
This knob can be used to select parameter item, adjust the 
value of the parameter and etc. 
  In menu operation, this knob can be used to open the 
submenu or select the desired parameter item. For 
menu item that include multiple parameter items, you 
can press the corresponding menu softkey and then 
turn the knob to select the specified parameter item 
(sometimes, you need to press down the knob to select 
the parameter item). This knob can also be used to 
modify the parameter, input fielname and etc. 
  In non-menu operation (the menu is hidden), turning 
the knob can adjust the waveform brightness. The 
adjustable range is from 0% to 100%. Turn the knob 
clockwise to increase the waveform brightness and 
counterclockwise to decrease the waveform brightness. 
Pressing down the knob can quickly reset the waveform 
brightness to 50%. You can also press Display  
WaveIntensity and then turn the knob to adjust the 
waveform brightness. 
 
 
Navigation Knob 
 
 
This knob provides quick adjust/locate function for 
numerical parameters with relatively larger settable ranges. 
Turn the knob clockwise to increase the value and 
counterclockwise to decrease the value. The inner knob is 
used for fine adjustment and the outer knob for coarse 
adjustment (the larger the rotation amplitude of the outer 
knob is, the faster the change speed of the value will be).  
 
For example, this knob can be used to quickly locate the 
waveform frame (Current Frame) to be played back in 
waveform playback. Similar parameters include trigger 
holdoff, pulse width setting, slope time and etc.
