When continuous flash or modeling flash is repeatedly fired in short
intervals, the temperature of the MR-14EX II may increase. Repeated
firings of the flash activates the flash firing restriction automatically to
avoid degrading and damaging the flash unit due to overheating. While
flash firing is restricted, the warning is displayed to indicate the increase
in temperature, and the firing interval is automatically set to approx.
from 8 up to 15 sec.
When the internal temperature of the flash unit increases, the warning is
displayed in two levels.
The following table shows the number of continuous flashes until the
warning is displayed indicating the Level 1 warning, and the necessary
rest time until normal flash shooting can be performed.
