TROUBLE SHOOTING 

 

Q:  

I press the button on the transmitter but my flash does not light up. Why?  

 
A:  

Please make sure that: 

 
1. 

The plastic wrapping on receiver’s battery has been removed.  

2. 

Batteries on both the transmitter and receiver are new.  

3. 

The receiver has been switched to “ON”. 

4. 

The channels of both the transmitter and receiver match each other.  

5. 

When  you  press  the  button  on  the  transmitter,  the  LED  on  the  receiver  and 
transmitter will light up.  

 
Q:  

The flash misfires even I did not press the button on the transmitter. What can 
I do?  

 
A:  

Although  this  trigger  has  advanced  anti-interference  design,  interference  from  the 
environment is still inevitable. Please move your setup to some other areas and try 
again.  If  misfiring  stops,  the  problem  may  come  from  the  interference  of  the 
environment.   

 

Interference may occur if you place flashes too close to each other. Try to move the 
flashes apart for at least 60cm / 2 feet. Misfiring problem should be resolved.  
 
If misfiring persists, switch to different channels and try again.
