Flash Firing Restriction Due To Temperature Increase - Canon SPEEDLITE EL-1 Advanced User's Manual

Flash Firing Restriction due to Temperature Increase

Temperature Increase Warning
Number of Continuous Flashes and Rest Time
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 flash unit 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.
