Laylax released a video guide on configuring the NEBULA 2 electronic trigger system in the Lancer Tactical Gen4 electric airsoft rifle. To start, users learn to enter the program mode by quickly moving the selector from Safe to Semi to Auto and back to Semi. Once in, five main settings are selectable using the trigger, with beeps indicating the chosen function: Auto shooting mode (1 beep), Semi shooting mode (2 beeps), trigger sensitivity (3 beeps), Pre-cocking (4 beeps), and Active Brake (5 beeps).

The tutorial details the options within each of the five settings, including different full-auto/burst modes, binary options, and adjustable trigger sensitivity. Saving a mode requires holding the trigger for three seconds. A key warning is given for Pre-cocking, an advanced feature that can cause gearbox stress and should be turned off for storage, while the Active Brake is noted to be on by default and usually doesn't require adjustment.
