20. Protection Feature
This unit is equipped with advanced overhea-
ting, over voltage, and over current warning
to prevent damage to the internal electronics.
NOTICE
Overheating protection:
After a long
shooting session at high output, the recyc-
ling time of the flash will increase automa
-
tically until the flash cools down to a safe
level and will start working normally again
.
NOTICE
Over voltage protection and over cur-
rent protection:
The flash is protected
against unstable voltages. Over current
protection is especially useful when using a
power pack.
21. Best Practices
• As with any flash units, the useful life of
the flash tube and the unit as a whole
depends on the way it is used. Avoiding
excessive heat is the key to long life.
• The fast recycling feature of the flash all
-
ows a rapid sequence of high power flas
-
hes to be obtained. However this feature
should be used sparingly since continuous
rapid flashing can cause overheating and
subsequent damage to the flash tube and
possibly the internal electronics.
• Rapid sequences of flashes should always
be followed by a reasonable cooling
period, at least 10 to 20 minutes is
advised either without flashing or at a sub
-
stantially reduced rate. This flash is fitted
with a cooling fan and will cool faster if left
switched on while modeling lamp off.
• Dimming or turning the modeling lamp off
will help prevent overheating.
