Thermal cut-out
The SB-5000 features a function that offers protection against damage
to the flash panel and body from overheating. This function does not
stop the flash head temperature rising. Be careful not to let the SB-5000
overheat during continuous flash use.
• The thermal cut-out indicator appears when the temperature of the
flash head rises as a result of the flash being fired numerous times in
quick succession. All operations except power ON/OFF and menu
settings are suspended to prevent heat damage to the flash panel and
body.

• Wait until the SB-5000 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.
