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.
•Master unit setting
Long press the [Mode]button to enter the
trigger mode selected interface,rotate the[
] until the LCD displays the < >to
enter wireless radio master unit state.Short
press the [MODE] button to swift the flash
mode of the master unit.
•Slave unit settings
Long press the [Mode] button to enter the
trigger mode selected interface,rotate the[ ]
until the LCD displays the< >to
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[ ] button
to enter the channel setting state,rotate the [
] to choose “AUTO” or choose the suitable
channel from 1 to 15,short press the [SET]
button for save.
ID setting:short press the function button [
]to enter ID waiting state,rotate the [
]to choose the position need to change,short
press the [SET] button to enter the
responding ID position to adjust the state,then
rotate the [ ] to choose the required number
from 0 to 9,and short press the [SET] button
to save the setting,press the function button [
]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[
]to enter the scan interface,the flash
LCD panel will display the scan results,the
higher the peak of which channel on the
chart,the stronger the radio the radio signals.
•The master flash on or forbid flash （ON/OFF）
When the YN686EX-RT as master unit to
process wireless radio transmission flash
shooting,you can choose if the master unit
participate in the flash or not. When the
master unit set to ON,the master unit will
participate the flash as Group A flash.Short
press the function button 4 to display < >,short press the
function button 1 [ ]to set the master unit to ON/OFF. <
>means the master unit flash ON， < >means the master unit
flash OFF。
•Use one to three slave units for transmission flash shooting
Short press the function button[ ] on
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:
RATIO OFF、RATIO A:B、RATIOA:B C（or
RATIO A:B:C）.Short press the function
button [ ] 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
Gr mode flashing,up to 5 groups
（A/B/C/D/E/F） of speedlite can be triggered
at the same time.Short press the [
]button,rotate the [ ]to select the flash
group which need to set the parameter,short
press the [ ]button to select the flash
mode（ETTL、M、OFF）,short press the[
]button and rotate the [ ] to adjust the
exposure compensation and flash
output.After the parameter set press the [
]button to return to the shooting ready
state.
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、YN600EX-RT
(II)、YN568EX II、Canon 600EX（II）-RT、580EX II、7D/60D/600D
cameras built-in flash,Nikon built-in flash C command and optical
transmission wireless signal.
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 subordinate unit.
The YN686EX-RT in optical transmission wireless flash shooting,up the
supports A、B、C three groups of slave unit flash control,with total four
channels（CH1/2/3/4） for option.The setting method of flash grouping
and transmission channel is the same as the wireless radio transmission
flash shooting.
•Master unit setting
Long press the [Mode]button to enter the
trigger mode selected interface,rotate the[
] until the LCD displays the < >to
enter wireless radio master unit state.Short
press the [MODE] button to swift the flash
modes between the ETTL、M、MULTI three
flash modes.
•Slave unit settings
Long press the [Mode] button to enter the
trigger mode selected interface,rotate the[
] until the LCD displays the< >to
enter wireless radio slave unit state. When
the YN686EX-RT used as slave unit,there are Sc、Sn、S1、S2 four
trigger modes for option.
Sc/Sn trigger mode can respectively receive the
YN686EX-RT,YN600EX-RT(II),YN568EX II,Canon 600EX（II）
-RT,580EX II,7D/60D/600D cameras built-in flash,Nikon built-in flash C
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.
You can custom the flash function according
to your requirement. Long press the function
button [ ] to enter the custom
function menu,rotate the[ ]to select the
custom function item(Number,such as C.Fn
01),short press the[SET]button to enter the
submenu,change the function settings
through the[ ] ,short press the
[SET]button for save settings and exit the
submenu.After the custom function setting
completed,press the[ ]button back to the shooting interface. After
entering the custom function menu,short press the function button [
]，then short press the function button[ ]will restore the
custom function to factory default.
