Thermal cut-out
The SB-910 features a function that offers protection against damage to the  ash
panel and body from overheating. This function does not stop the  ash head
temperature rising. Be careful not to let the SB-910 overheat during continuous
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.

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.
