Flash Firing Restriction Due To Temperature Increase - Canon Speedlite EL-5 Advanced User's Manual

Flash Firing Restriction Due to Temperature Increase

Temperature Increase Warning
Continuous Flash Count and Rest Time
Repeated use of continuous, stroboscopic, or modeling flash at short intervals may increase
the temperature of the flash head, battery, and areas near the battery compartment.
Repeated flash firing gradually increases the firing interval, up to approx. 4 sec., to
avoid wearing out or damaging the flash head from overheating. Continuing to fire in
this state will automatically restrict flash firing.
Note that when flash firing is restricted, a high-temperature warning icon is displayed,
and the flash photography firing interval is automatically set to approx. 8 or 20 sec.
(levels 1 and 2, respectively).
Temperature Increase Warning
At each of the two levels, a different warning icon is displayed as the internal temperature
rises. Continuing to fire after level 1 is reached changes the state to level 2.
