3.  Under ALL mode, all of units will join in firing.

   

1.  A:B can set different flash output of group A and B 

individually, except group C. The frequency and flash times 
of group A and B are the same;

2.  A:BC can set the flash output of group A, B, C. The flash 

power of the three groups can be set separately. And the 
frequency and flash times of the three groups are the same;

3.  Under ALL mode, all of units will join in firing. The frequency 

and flash times of every firing group are the same.

※ Under MULT mode of wireless flash, flash frequency can be set 

between 1-199Hz.

When an error occurs on the flash or overheating protection is 
activated, the following information will display on the screen:

Motor Error Prompt:
WARNING: MOTOR ERROR
Motor Error, Battery and Flash Head Overheating 

Prompt:
WARNING: MOTOR ERROR BAT LAMP TEMPERATURE

Motor Error, Flash Head Overheating Prompt:
WARNING: MOTOR ERROR LAMP TEMPERATURE

Flash Head Overheating Prompt:
WARNING: LAMP TEMPERATURE

Battery Overheating Prompt:
WARNING: BATTER TEMPERATURE

Unknown Error Prompt:
WARNING: ERROR 90

※ When a prompt occurs on flash motor and unknown error, you are 

advised to switch on-off the flash repeatedly to make it self-recovery. 
After recovery, the prompt info will disappear, and you can reuse it. If 
not, you are advised to contact the dealer for repair.

※ When you use the flash continually, flash head and battery overheating 

protection will be activated, then the LCD display screen will shows 
error prompt and restrict flash firing. Now please turn off the flash and 
allow a rest time for reuse. Then the prompt info will disappear, and you 
can reuse it.

X900  Speedlite  is  the  newest  one  developed  by  Pixel  which 
has  multifunction  and  fast  recycle  time.  Featured  with  fast 
recycle time, it can use Lithium battery, AA battery and can be 
used  with  Pixel  power  bank  TD-386  which  has  high  power 
capacity. When use lithium battery or power bank TD-386, the 
recycle time is less than 1.5 sec, full power output is up to over 
700 times that makes you cannot miss the amazing moment; It 
has  the  configurations  of  HSS,  high  GN,  wireless  control, 
stroboscopic and so on. The frequency of stroboscopic is up to 
500  times,  the  performance  is  more  strong  and  stable;  In  the 
area  of  controlling  Speedlite,  beside  the  optical  control,  it 
imports wireless control system FSK2.4GHz and supports the 
direct  wireless  control  between  King  PRO,  Speedlite  and 
Speedlite  making  the  match  between  speedlites  more  free. 
X900  Speedlite  ingeniously  adopts  4  watt  full  white  light  LED 
creative set light, LCD lattice screen with high definition,multi-
matrix  overheat  warning  system  and  other  thoughtful 
equipment.  It  is  a  Speedlith  with  high  performance,

X900 master mode

King pro master mode

The master mode setting of King Pro: After power-on, gently 
pressing the right first button on the king pro installed on the 
camera, entering into the setting of master mode and slave 
mode to set the mode by pressing the left first button that will be 
display a “+” on the screen and the second button that will 
display a “-” on the screen. Then, pressing   the first left button 
that will display an “OK” on the screen.
The master/slave mode setting of X900: you can enter into the 
master mod by pressing the first upper left button on flash for a 
long time (the button of “RMOT”) and choose FSK2.4GHz 
wireless mode as flash mode. [       ]

Both Wireless trigger King pro and x900 pro have FSK2.4GHz 
wireless  control  mode,  and  X900  Speedlite  has  a  built-in 
wireless receiver; When used with king pro, the x900 pro flash 
can be controlled without Receiver and all kinds of flash modes 
can  be  controlled  by  king  pro,  for  example:  TTL,  M,  focal 
length,  exposure  compensation  and  so  on；At  the  same  time, 
two flashes can be used in wireless flash mode through 2.4GHz 
communication without any trigger. (Beside FSK2.4GHz mode, 
x900  pro  has  optical  mode.  The  introduction  is  about  the 
operation mode of FSK2.4GHz)

Please make sure the communication mode, channel and group 
of  king  pro  and  x800  pro  are  correct,  otherwise  they  cannot 
communicate  and  be  used  normally.The  king  pro  and  x800  pro 
installed  on  the  end  of  camera  should  be  set  as  master  mode, 
the  off-camera  flash  should  be  set  as  slave  mode;  then,  the 
group of master mode and slave mode and the channel should 
be set as the same.

Pressing the button of “RMOT” for 
a long time, you can enter into the

Optical transmis-sion flash is achieved by optical pulse, 
not  wireless  signal  transmission,  so  the  transmission 
distance is very short. Please note the following issues 
when using:

1.   Make  sure  the  slave  unit  within  effective  control  range 

when using optical transmission flash mode;

2.  The receiving signal sensor of slave unit should face to 

master unit;

3.   You  are  required  to  use  flashes  that  are  equipped  with 

an optical transmission wireless shooting function;

4.   Please  do  not  place  any  obstacles  between  the  master 

unit  and  salve  unit  when  using  optical  transmission 
flash mode, or it may affect optical signal transmission;

5.   Under  optical  transmission  flash  mode,  use  ETTL  flash 

and  M  flash  support  high  speed  sync  (HSS)  and  1st
