Always set the power/mode switch to [OFF] when you finish using the flash. • Be careful not to touch the flash window or sensor windows with your fingers while the flash is in use. • In outdoor settings in the daylight, the flash may not detect illumination from the camera's built-in flash and may not fire. • The flash may fire if another flash is being used in close proximity. • The flash may not fire if there are no reflective items in its metering field. • For continuous shooting, although the flash fires for the first shot, it does not fire for subsequent shots. • If the battery usage time has considerably diminished, wipe the battery terminals well with a dry cloth as the terminals may be soiled with oil from one's skin or other dirt. 170
