Functions
Thermal cut-out
The SB-910 features a function that offers protection against damage to the fl ash
panel and body from overheating. This function does not stop the fl ash head
temperature rising. Be careful not to let the SB-910 overheat during continuous
fl ash use.
The thermal cut-out indicator appears when the temperature of the flash panel •
and body rises as a result of the flash being fired numerous times in quick
succession, and all operations except power ON/OFF and custom settings are
suspended before the heat can damage the flash panel and body.

Wait until the SB-910 cools down. •
Operation can be resumed once the warning is no longer displayed. •
On rare occasions, the thermal cut-out indicator might appear or disappear •
without the temperature changing depending on the zoom head position. This is
not a malfunction.
