Caution
Do not open or close the battery compartment cover while flash firing is restricted.
This will cancel the flash firing restriction, which is potentially very dangerous.
The firing interval becomes longer as the flash head becomes hotter, even if no
level 1 warning is displayed.
After a level 1 warning appears, stop using the Speedlite for at least 40 min.
Even if you stop firing after a level 1 warning appears, a level 2 warning may still be
displayed.
