This wireless flash trigger is suitable for using Canon cameras to control Godox flashes with X system e.g. camera flash, outdoor flash, and studio flash. It can also control Canon original speedlites with the coordination of X1R-C receiver. Featuring multi-channel triggering, stable signal transmission, and sensitive reaction, it gives photographers unparalleled flexibility and control over their strobist setups. The flash trigger applies to hotshoe-mounted Canon EOS series cameras, as well as the cameras which have PC sync sockets. With XProC wireless flash trigger, high speed synchronization is available for most of camera flashes in the market which support E-TTL II. The max flash synchronization speed is up to 1/8000s *.

*: 1/8000s is achievable when the camera has a max camera shutter speed of 1/8000s.

Attentions As the products needs to do firmware upgrade, please refer to instruction manual of the newest electric version as final. 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 isnt 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.
