To avoid overheating and degrading the flash head,
do not fire more than 20 flashes continuously. After
20 continuous flashes, allow a rest time of at least
10 min.
If you fire more than 20 continuous flashes and
then fire more flashes in short intervals, the inner
overheating prevention function may be activated
and make the recycling time about 8 to 20 sec. If
this occurs, allow a rest time of about 15 min. and
the flash will then return to normal.
Cautions for firing continuous flashes

1Open the cover.
Slide the battery compartment cover
as shown by the arrow and open it.
2Install the batteries.
Make sure the + and – battery
contacts are correctly oriented as
shown in the battery compartment.
3Close the cover.
Close the battery compartment cover
and slide it as shown by the arrow.
Based on new AA/LR6 alkaline batteries and Canon’s testing standards.
Installing the Batteries
Recycling Time and Flash Count
Recycling Time (Approx.) Flash Count (Approx.)
0.1 - 2.3 sec. 180 - 1000
Using AA/LR6 batteries other than the alkaline type may cause improper
battery contact due to the irregular shape of the battery contacts.
If you change the batteries after firing many flashes continuously, be
aware that the batteries might be hot.
Use a new set of four batteries of the same brand. When replacing the
batteries, replace all four at one time.
AA/LR6 rechargeable Ni-MH or lithium batteries can also be used.
