If you feel a Speedlight gate is in a mode where it is not responding as expected, it can be reset by
- Hold the 'ON' button down until you hear a beep. This has forced the gate to reboot.
- Below the Digital I/O connectors there is a tiny, unmarked hole approximately 1mm across. Poking a paperclip through this hole will force a hardware reset. NOTE: Never poke any object into the LASER ALIGNMENT hole as electronic damage may occur.
