To Set Start Phase 
 
The setting range of start phase is from 0° to 360°. The default is 0°. 
 
The start phase displayed on the screen is the default value or the phase previously 
set. When the instrument function is changed, the new function will still use this 
phase. 
 
Tap the Phase parameter input field to input the desired phase value with the 
numeric keypad, then select the unit "°". Tap "Ok". 
 
You can also use the arrow keys and the knob to set the parameter value: press 
down the knob to enter the editing mode, use the arrow keys to move the cursor to 
select the digit to be edited, and then rotate the knob to modify the value. Besides, 
you can use the knob to switch between different parameters.
