Insert one end of the Fiber Optic Cable into UCS-Q1 Fiber Optic Cable Port and 

the other end to fiber optic port of the camera housing.

The UCS-Q1 will analyze your camera’s flash and automatically synchronize after 

the first test shot. First, power on the strobe and select any Strobe Power setting 

from 1-7 and take a single test shot. The UCS-Q1 will analyze the 1

st

 test shot and 

memorize  the  Flash  Synchronization  setting  for  your  camera.  If  you  change 

cameras or flash settings on your camera, simply power off the UCS-Q1, power on 

and  take  another  test  shot  to  synchronize  with  your  new  camera  or  camera 

settings.

If shooting in extremely bright ambient light conditions, the LED light may not be 

bright enough for targeting purposes. Press and hold the          button for 1 second 

and the strobe will emit a bright, high frequency stroboscopic pulse for about 2 

seconds. This rapid firing of the strobe will help in targeting the subject in bright 

ambient light conditions.
When  using  the  Snoot  (AOI  SNT-01,  optional  accessory  sold  separately),  the 

Modeling Flash also serves as a target light.

The  UCS-Q1  is  equipped  with  the  overheat  protection  circuit.  If  the  strobe  has 

been in continuous use, the internal electronics temperature may increase, the 

recharging  time  /  recycle  time  will  slow  down  automatically

If  the  overheat 

protection circuit is activated and the Indicators    and    will blink Blue & Purple 

alternately (see Table 1, Page 9). The strobe will be suspended temporarily. After 

cooling down, the Indicators     and     will be back to normal and all the functions 

will be resumed.

IMPORTANT: 

Wipe the strobe dry and keep seawater away prior to opening the 

battery cap. Do not allow seawater to be in contact with the interior parts of the 

battery compartment, otherwise it may cause rust, corrosion or malfunction.

If  seawater  leaks  into  the  battery  compartment,  please  turn  off  the  power  and 

remove the batteries immediately. Rinse the battery compartment with fresh water
