Getting Started and Basic Operations

Caution

• Precautions on continuous flash firing

• To avoid wearing out or damaging flash heads from overheating, do not fire the flash continuously at full output more than approx. 40 times. After firing continuously at full output this many times, stop using the Speedlite for at least 40 min.
• After continuous firing at full output this many times, further continuous firing at short intervals may activate a safety function that restricts firing. At a firing restriction level of 1, the firing interval is automatically set to approx. 8 sec. In this case, stop using the Speedlite for at least 40 min.
• For details, see Flash Firing Restriction Due to Temperature Increase.
