Flash Firing Restriction Due To Temperature Increase - Canon 600EXII-RT Instruction Manual

f Flash Firing Restriction due to Temperature Increase
When continuous flash, stroboscopic flash, or modeling flash is
repeatedly fired in short intervals, the temperature of the flash head,
batteries, and the area near the battery compartment may increase.
When you perform firing repeatedly, the firing interval increases in
steps within the range of up to approx. 4 sec. to avoid degrading
or damaging the flash head due to overheating. When you perform
firing repeatedly even more in this state, flash firing is restricted
automatically.
Furthermore, when flash firing is restricted, a warning icon is
displayed to indicate the increase in temperature, and the firing
interval (with which the flash photography can be performed) will
be automatically set to approx. 8 sec. (level 1) or approx. 20 sec.
(level 2).
Temperature Increase Warning
As the internal temperature of the Speedlite increases, the warning is
displayed in two levels. When you perform continuous firing repeatedly
even more in the state in level 1, the state changes to level 2.
