Figure 33. Quick mode - phase shift modification
Phase shift can be modified like the duty cycle and frequency. Use the Up/Down keys to
increase/decrease the digit and Left/Right to navigate to other digits within the parameter. You
can press OK to confirm the entered phase shift, so the device will return to the main screen or
press BACK to go to duty cycle modification mode.

You can enable/disable the LEDs from any menu / screen just by pressing the LED ON/OFF key.
When the device is in the main screen, the colour of the frequency reading will change from white
(LEDs off) to orange (LEDs on) when the LED ON/OFF key is pressed.
