• After a series of flashes with full power and
short intervals, a pause of at least 3 minu-
tes must be observed after each series of
20 flashes!
• When taking a series of flash shots at full
light output and with rapid recycling times,
and with zoom positions of 35 mm and
less, the diffuser heats up, due to the high
level of thermal energy!
• This flash unit may be used in combination
with a camera-integrated flash only if the
flash can be folded out completely!
