Troubleshooting

Flash is not firing on camera

Ensure the flash is fully seated in the hot shoe and the locking mechanism is engaged. Check that the camera's shutter speed does not exceed its sync speed if HSS is not enabled.

Wireless connection failing

Verify that both the master and slave units are set to the same channel and group ID. Ensure the wireless transmission mode is active.

Recycle times are too slow

Replace the AA batteries with fresh, high-capacity rechargeable batteries. If using a power pack, check the connection cable.

Setup, Compatibility & Care

To begin using the TT685II-F, slide the unit onto your Fujifilm camera's hot shoe and lock the mounting mechanism. Ensure your camera is set to the correct flash mode in the menu. For firmware updates, utilize the USB Type-C port on the side of the unit; always check the Godox website for the latest version. For maintenance, keep the flash head clean and dry. Since the unit uses 4 AA batteries, it is recommended to use high-quality rechargeable NiMH batteries to maintain the 2.6-second recycling time. If you shoot at high power for extended periods, connect an external power pack to the dedicated port to avoid thermal shutdown and slow recycling.
