| Problem | Possible Cause | Solution | |---------|---------------|----------| | Transmitter and receiver won’t pair | Out of range, interference, or defective unit | Check distance (max 60m), remove potential interference sources (other 2.4GHz devices), try manual pairing using the code‑setting button. If still fails, consider returning the unit for replacement. | | Camera doesn’t trigger | Cable not properly connected, camera not in correct mode | Verify the connection cable is securely plugged into both receiver and camera. Ensure your camera is in a mode that accepts remote triggering (e.g., not in playback mode). Test with the shutter button directly on the camera. | | Intermittent signal | Signal interference or low batteries | Move closer to the receiver (within 30–40 meters). Replace AAA batteries. Check the wireless signal strength icon on the LCD—if it’s low or absent, you’re out of range. | | Shutter stays open (Bulb mode) | Basic Bulb mode (B) doesn’t use timer | If you want automatically timed long exposures, use the timer function instead of basic B mode. For basic B mode, you must press the shutter button twice (once to open, once to close). | | Unit stops mid‑sequence | Batteries depleted | The unit has no battery indicator, so carry spare batteries. | | Crossover with another user’s device | Frequency interference | In crowded environments (photo workshops, events), try re‑pairing or moving away from other 2.4GHz devices. |
