of the RF60X Master in S1 (the
mode in which the flash is

RF60X Master with its optical
sensor facing the flash head of
the TTL flash.
5. Take a test shot by pressing the
camera’s shutter release button.
6. If the frame is not evenly
illuminated from top to bottom,
set the delay timer (see Section
11.4) of the RF60X Master to 10 ms
and then 15 ms, 20 ms, etc., until
the flash fully f
ills up the
frame.
The optimum delay time
that works with a high shutter
speed should be within the range
of 10 ms to 100 ms.

flash is set to M (Manual) mode,
the delay time should be within
the range of 0-10 ms. If the TTL
flash is set to TTL mode, you would
have to set a delay time at
55-100 ms, depending on the camera
brand and shooting aperture
(F-number).
