Attentions
Troubleshooting Triggering Issues:
- Unable to trigger flash or camera shutter: Ensure batteries are installed correctly and the power switch is ON. Verify the transmitter and receiver are on the same channel, the hot shoe/cable connection is secure, and the trigger is in the correct mode.
- Camera shoots but does not focus: Check if the camera or lens focus mode is set to MF. Change it to AF if necessary.
- Signal disturbance or shooting interference: Change the channel on the device.
- Operating distance limited or flash missing: Check if batteries are exhausted and replace them if needed.
Reasons & Solutions for Not Triggering in Godox 2.4G Wireless:
- Interference from 2.4G signals: Adjust the trigger's
CHsetting (add 10+ channels) to an unused channel or turn off other 2.4G devices. - Flash not ready or overheating: Ensure the flash has finished recycling (ready indicator is lit) and is not in overheat protection mode. Try reducing flash power output. If in TTL mode, switch to M mode (requires a preflash).
- Distance between trigger and flash: Enable "close distance wireless mode" on the trigger (for distances < 0.5m) or set
C.Fn-DISTto0-30m. - Low battery on trigger or receiver: Replace batteries. 1.5V disposable alkaline batteries are recommended for the trigger.
Caring for Flash Trigger
- Avoid sudden drops, shocks, impacts, or excessive stress, as the device may fail to work.
- Keep the product dry. It is not waterproof. Malfunction, rust, or corrosion may occur if exposed to water or high humidity.
- Avoid sudden temperature changes. Condensation can form when moving from a warm environment to a cold one. Place the device in a handbag or plastic bag beforehand.
- Keep away from strong magnetic fields, as static or magnetic fields from devices like radio transmitters can cause malfunction.
