Modus 600RT 21
Flash Output Power 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: 1/2,
1/2-0.3, or 1/2-0.7, or increase the ash output:1/2,
1/2+0.3, 1/2+0.7, 1/1.
Figures displayed when reducing ash output level→
1/1 1/2 1/4
1/1-0.3 1/2-0.3 ------1/1-0.7 1/2-0.7
1/2+0.7 1/4+0.7 ------1/2+0.3 1/4+0.3

Optical O1 Secondary Unit Setting
In M manual ash mode, press <O1/O2> button so that
this ash can function as an optical O1 secondary ash
using its optical sensor. With this function, the ash will
re synchronously when a second main ash res. This is
the same effect as usng a radio trigger to re the ash off
camera. This helps create multiple lighting effects.
Optical O2 Secondary Unit Setting
In M manual ash mode, press <O1/O2> button so that
this ash can function as an optical O2 secondary ash
using its optical sensor. With this function, the ash will
re synchronously when a second main ash res as in
O1 but it will ignore the metering pre-ash and re only in
response to the exposure ash from the main unit.
• O1 and O2 optic triggering is only available in M manual
ash mode when the Modus 600 RT is off camera
• Press function button 4 <
SYNC
> to activate the “HSS”
when in 01/02 mode
Flash Mode: MULTI (Stroboscopic
Flash)
With stroboscopic ash, a rapid series of ashes is red.
It can be used to capture multiple images of a moving
subject in a single photograph.
You can set the ring frequency (number of ashes per
sec.expressed as Hz), the number of ashes, and the
ash output power.
1. Press <MODE> button
