If the camera's precise f-number cannot be set on
the mecablitz, then select the one that comes clos-

preflash suppression
The mecalux slave mode with measuring preflash
suppression is intended specifically for digital
cameras featuring a measuring preflash function.
Various digital cameras fire a measuring preflash
fractions of a second prior to flash exposure. To
prevent the mecablitz from being triggered by this
measuring preflash, the operating mode selector
must be set at position to ensure that the
mecablitz is triggered by the time the main flash is
fired. Light output control of the slave unit is in
accordance with the selected operating mode
(automatic flash mode A or manual flash mode M).
