• The flash will start charging. When the flash
is ready, the pilot lamp lights.
● Red pilot lamp
When the flash is fully charged, the pilot
lamp lights in red. For normal use, confirm
that the pilot lamp is red before taking the
picture.
● Yellow pilot lamp
When the camera is set for single shooting, a
yellow pilot lamp indicates a less-than-full
charge which enables a quick flash (see
description below). For close subjects which
do not require full-output flash, quick flash
shortens the recharging time.
To test the Speedlite, press the pilot
lamp (test firing button) to fire a test
