Attentions

1. Unable to trigger flash or camera shutter. Make sure batteries are installed correctly and 

Power Switch is turned on. Check if the transmitter and the receiver are set to the same 
channel, if the hotshoe mount or connection cable is well connected, or if the flash 
triggers are set to the correct mode. 

2. Camera shoots but does not focus. Check if the focus mode of the camera or lens is set 

to MF. If so, set it to AF.

3. Signal disturbance or shooting interference. Change a different channel on the device.
4. Operating distance limited or flash missing. Check if batteries are exhausted. If so, 

change them.

Caring for Flash Trigger

Avoid sudden drops.

 The device may fail to work after strong shocks, impacts, or 

excess stress. 

Keep dry.

 The product isn

'

t water-proof. Malfunction, rust, and corrosion may occur and 

go beyond repair if soaked in water or exposed to high humidity. 

Avoid sudden temperature changes.

 Condensation happens if sudden temperature 

changes such as the circumstance when taking the transceiver out of a building with 
higher temperature to outside in winter. Please put the transceiver in a handbag or 
plastic bag beforehand.

Keep away from strong magnetic field.

 The strong static or magnetic field produced 

by devices such as radio transmitters leads to malfunction.
