Cautions for firing continuous flash
To avoid degrading and damaging the flash unit due to overheating, limit
the continuous firing at full output to 20 times or less. After continuously
firing the flash 20 times, allow a rest time of at least 10 min.
If you fire the flash continuously 48 times and then fire the flash again
repeatedly at short intervals, the safety function may activate and
restrict flash firing. With flash firing restriction, the firing interval is
automatically set to approx. 8-20 sec. If this happens, allow a rest
time of at least 25 min.
For details, see "Flash Firing Restrictions due to Temperature
Increase" on page 28.
