Nikon 58-104 manual Heat alert light blinks

Heat alert light blinks.

When the interior of the 88-104 overheats due to successive firing of the flash or other factors, the heat alert light blinks. Operation of the 88-104 stops automatically.

-The flash can be used again after it has cooled down and the lamp has stopped blinking .

Electrical alert light blinks.

If one or both flash tubes did not fire, the electrical alert light blinks to alert you .

-Bring the Speedlight to a Nikon service center to have it checked.

+Note

Each time the flash is fired, the SB-104 checks to be sure both flash tubes have fired normally. If both flash tubes fires abnormally, the Flash Abnormality lamp blinks after firing. If the lamp blinks even though the SB-104 has fired, one of the two flash tubes is defective.

If the shutter is released before the ready- light goes on , the flash will not fire and the flash abnormality lamp will blink. However, there is no abnormality in this case.
