Be sure to use a new set of two batteries of the same brand. When replacing the batteries, replace both batteries at once.

Do not fire more than 20 continuous flashes in a short time.

If you fire more than 20 continuous flashes in a short time, the 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 functioning of the flash will then return to normal.

If you change the batteries after firing flashes continuously, be aware that the batteries might be hot.

Using size-AA/LR6 batteries other than the alkaline type may cause improper battery contact due to the irregular shape of the battery contacts.

Size-AA/LR6 Ni-MH or lithium batteries can also be used.
