parameters from being changed accidentally.
3.Test Flash
When the charging indicator turns red,
pressing [
] button to test if the flash is
normal or not.
4.ETTL Mode
Short press [MODE] button to set the flash
mode as ETTL mode. In ETTL mode, the light
measuring system of the camera can detect
the flash lighting reflected from the subject,
adjust the flash output amount automatically
and makes the subject and the background
expose evenly. YN686EX-RT supports FEC, FEB, high-speed sync,
second-curtain sync, exposure lock, aperture preview, menu access of
Canon camera, etc.
In ETTL mode, the flash intensity can be compensated. The
compensation range is -3EV~+3EV; the accuracy is 1/3EV or 1/2EV.
5.M Mode
Short press [MODE] button to set the flash
mode as M mode. In M mode, the flash
intensity can be asjusted according to your
own need. By short presssing functional
button [
] , a f t e r < F l a s h O u t p u t > i s
highlighted, the flash output power can be
adjusted when you rotate [ ]. Adjustement
range of flash output in M mode is 1/128~1/1.
The output can be divided into 8 grades.
Each grade has maximum 3 grades for find
adjustment. With 1/3EV as adjustment
increment, there are totally 22 grades for fine
adjustment. In shooting, you just need to set flash output, adjust the
camera and press camera shutter, the flash fires when it receives sync
signal from the camera.
6.Multi (Stroboscopic) Mode
Short press [MODE] button to set the flash
mode as Multi (stroboscopic) mode. In Multi
mode, the speedlite fires according to the
selected flash output, flash frequency and
number of flashes. The setting method of
flash output is same as setting method in M
m o d e . T h e f l a s h o u t p u t r a n g e i s
1/128-1/64-1/32-1/16-1/8-1/4. Select number
of flashes through functional button [
]
and select flash frequency through [ ]
button. Enter into parameter setting status
and rotate [ ] to adjust number of flashes
and flash frequency. The range of number of flashes is 1~100; the range
of flash frequency is 1~100.
When using this function,the focus mode of the camera should be set to
one-shot AF
（

]
f l a s h i n g
alternatively.When the overheat protection is
triggered,the speedlite will be locked, the
parameter cannot be adjusted and the
speedlite cannot flash.In this case,please
keep the speedlite idle for over 10 minutes
until the speedlite cools down for continual
use.In order not to affect shooting,please try
to use 1/4 output or lower output level when fast shooting is needed.
13. Sound Prompt Function

flash mode and flash output of slave unit will be totally controlled by the
master unit.
Sc trigger mode:
only accept the Canon optical transmission wireless
flash signal
Sn trigger mode:
only accept the Nikon optical transmission wireless
flash signal
S1/S2 trigger mode is respectively suitable for the manual flash
environment and TTL flash environment.When the YN686EX-RTin
S1/S2 trigger mode, the flash mode will default to M mode, the setting
method of flash output is the same as set top M mode.
S1 mode:
In this mode it will work with the first flash synchronously of
the master flash, with the result consistent with the use of radio slave. To
use this mode properly, the master flash should be set to manual
flash,should not use the TTL flash system with preflight function and the
red eye reduce function with multiflash.
S2 mode:
It is also called “pre-flash cancel mode” . This mode is similar
with S1 mode, but it can neglect the pre-flash given by TTL flash.
Therefore, it can support the master flash working in TTL mode. In
particular, if S1 mode cannot flash properly and sync with your internal
flash, you can try to use S2 mode.
