M: Manual Flash
The ash output is adjustable from 1/1 full power to 1/128th pow-
er in 1/3rd stop increments. To obtain a correct ash exposure,
use a hand-held ash meter to determine the required ash out-
put.
1
Press < MODE > button so
that < M > is displayed.
2
Turn the Select Dial to
choose a desired ash out-
put amount. In high-
speed sync mode, the ad-
justable ash range is
1/16~1/1.
Flash Output Range
The following table makes it easier to see how the stop changes
in terms of f/stop when you increase or decrease the ash output.
For example, when you decrease the ash output to 1/2, 1/2-0.3,
or 1/2- 0.7, and then increase the ash output to more than 1/2,
1/2+0.3, 1/2+0.7, and 1/1 will be displayed.

In the M mode,
high-speed sync and second curtain sync
functions can be achieved.
Optical S1 Secondary Unit Setting
In M manual ash mode, press the < SLAVE > button so that this
ash can function as an optic S1 secondary ash with optic sen-
sor. With this function, the ash will re synchronously when the
main ash res, the same effect as that by the use of radio trig-
gers. This helps create multiple lighting effects.
Optical S2 Secondary Unit Setting
Press the < SLAVE > button so that this ash can also function as
an optic S2 secondary ash with optic sensor in M manual ash
mode. This is useful when cameras have pre-ash function. With
this function, the ash will ignore a single “preash” from the
main ash and will only re in response to the second, actual ash
from the main unit.
• S1 and S2 optic triggering and off camera high-speed
mode are only available in M manual ash mode.
