Getting Started and
Basic Operations
This chapter describes the preparations before starting
flash photography and the basic shooting operations.
Cautions for firing continuous flash
To avoid degrading and damaging the flash head due to
overheating, do not fire more than 20 continuous flashes.
After 20 continuous flashes, allow a rest time of at least 10
min.
If you fire 20 continuous flashes, and then fire the flash
again repeatedly with short intervals, the safety function
may activate and restrict flash firing. While flash firing is
restricted, the firing interval is automatically set to approx. 8
to 25 sec. If this happens, allow a rest time of at least 20 to
30 min.
For details, see “Flash Firing Restriction due to Temperature
Increase” on page 92.
