1.Wireless Radio Transmission
The YN686EX-RT supports wireless radio transmission flash
shooting,realize wireless TTL,manual and stroboscopic function. As the
master unit,the speedlite can trigger the YONGNUO and Canon RT
series speedlites,such as the YN600EX-RT II/YN968EX-RT/600EX
II-RT/430EX III-RT;as the slave unit, the same YN686EX-RT can
respectively receive the YONGNUO and Canon RT series speedlites
and the wireless signal of YN600EX-RT II/YN968EX-RT/600EX
II-RT/YN-E3-RT/ST-E3-RT.
The flash mode,manual flash output,exposure compensation,exposure
bracketing,exposure locking and etc settings of the master unit will be
automatically transfer to each slave unit.

enter wireless radio slave unit state. When
the YN686EX-RT used as slave unit,the flash
mode will be totally controlled by the master unit.If the master unit and
slave unit are set the exposure compensation,the exposure
compensation value from both units will be superimposed.
•
Transmission channel/Radio ID set
In public if there are other photographers in use of the wireless radio
multiple flash or other radio equipment, you can change the
transmission channel and radio ID to avoid the interference.The
YN686EX-RT is equipped with 15 physical channels,an automatic
channel and 10000 ID for option .
Channel setting: short press the

]
to return to the wireless interface.
In the wireless radio transmission flash
shooting process, make sure the transmission
channel and ID setting of the master unit and slave unit are the
same,otherwise the flash could not work normally. When the master unit
and the slave unit make connection establishment, the <LINK>indicator
will be in green light.
•
Scan the master unit transmission channel
You can scan the radio receiving state and automatically or manually set
the transmission channel of the master unit.
When the channel set to “AUTO” ,it will
automatically set the received signal
channel.When manually set the channel,you
can reset the transmission channel at the
same time in the reference scan results.
Scan setting: short press the function button

the slave unit and set the slave unit as any
group of group A,B,C.
Short press the function button on the master
unit to set the flash group,each short press[
],the setting change will change by:

RATIOA:B C
（
or
RATIO A:B:C

and rotate the [ ] to select the
flash group which need to set the flash ratio
and flash output,then short press the
[
]
button to enter the flash parameter
setting state,through rotate the [ ]to adjust the flash ratio,exposure
compensation or flash output of the group flash.
If you need larger output or hope for better
lighting,you can increase the number of speedlite
on one slave group for maximum total 15 units.
For example: if the three slave units set to group
A,they will be seen as one speedlite and
controlled by the master unit.
•
Gr:set different flash mode and flash output on each group of
speedlite to process transmission flash shooting
Short press the [mode] button on the master
unit and set tot Gr mode, then set the slave
units group with different flash mode and
flash output through the master unit. When in

2.Optical Transmission
The YN686EX-RT supports optical transmission wireless flash
shooting,realize wireless TTL,manual and stroboscopic function.As
master unit,the speedlite can trigger the YONGNUO EX series
speedlite(excluding the YN585EX) through the wireless radio
transmission;as the slave unit, the same YN600EX-RT II can
respectively receive the wireless signal of YN686EX-RT

command and optical transmission wireless signal,realize off camera
TTL and manual flash.When the YN686EX-RT in Sc/Sn trigger mode,the
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.
1.Unable to turn on the power source or unable to flash.
Please check whether the battery is installed correctly and with enough
electricity;When using an external battery box, also need to install four
AA batteries on flash;Please ensure that the flash hot shoe properly
installed on the camera hot shoe and the flash knob lock fixed.
2.Could not flash in optical transmission wireless flash
shooting.
When using outdoors, please avoid direct sunlight to the flash wireless
sensor;Ensure the master unit and the slave unit channel set to
consistent, and the slave unit is located in the effective wireless
transmission range of the master unit.
3.Could not flash in wireless radio transmission.
Please make sure that the channel and ID of the master unit and the
slave unit to consistent, and the slave units placed in the effective
wireless transmission range of the master unit.
4.Photo underexposure or overexposure.
Check if the current camera shutter, aperture, sensitivity (ISO) is too
close to the limit of the flash, or if the exposure compensation, exposure
bracketing and relevant settings on the camera and flash are correct.
5.The photos appear dark corners or subject object can
only partial light up.
Please check the current flash coverage;Please check whether the lens
focal length is beyond the range of the flash, if excess you can try to pull
out the wide panel to enlarge the coverage of the flash.
6.The flash control panel display blurred.
There is a layer of film on the screen when it out of the factory, you can
tear it to enjoy more clear visual effect.
7.Flash in error state.
Please try to turn off the flash and remove it from the camera.Then
install on the camera and restart the flash. If the problem still not be
solved,please contact to YONGNUO after-sale service center with hot
line 400-001-3888.
