4. Operation

4.1 Operating Modes

The TT350O supports various flash modes. Press the Mode Selection Button (2) to cycle through them.

• TTL Autoflash Mode: Light levels are measured through the lens, and the flash automatically sets the correct exposure. This mode simplifies shooting by automating flash output.


Figure 4.1: Effect of TTL Autoflash.

• Manual Flash (M) Mode: Allows manual control over flash output from 1/128 to 1/1 power, with 22 levels of fine adjustment. Use the Select Dial (14) to adjust power.
• Multi Flash Mode: Used for stroboscopic photography to capture multiple images of a moving subject in a single frame. Adjust flash frequency and number of flashes using the Select Dial (14).
• S1/S2 Optical Slave Modes: These modes allow the TT350O to be triggered by another flash unit optically. S1 mode triggers the flash upon detecting the main flash. S2 mode ignores the pre-flash of a TTL system and triggers on the second flash.
• High-Speed Sync (HSS): Enables flash synchronization at shutter speeds faster than the camera's native sync speed (up to 1/8000s). This is useful for freezing fast motion or using flash in bright ambient light.
• Front Curtain Sync / Rear Curtain Sync: Front curtain sync fires the flash at the beginning of the exposure. Rear curtain sync fires the flash at the end of the exposure, creating a motion blur effect behind the subject.

4.2 Wireless Flash Function (2.4G X System)

The TT350O can operate as both a master and a slave unit within the Godox 2.4G wireless X system.

• As a Master Unit: The TT350O can control other Godox slave flashes such as AD600Pro, AD600Pro II, AD300Pro, AD400Pro, AD200Pro, AD200Pro II, AD200, V860III-O, V850II, V850III, TT685IIO, TT600.

4.3 Flash Head Adjustment

The flash head can be rotated and tilted to bounce light off surfaces, providing softer and more natural illumination.

• Vertical Rotation: The flash head can tilt from -7° to 90°.
• Horizontal Rotation: The flash head can rotate 0° to 270°.

To adjust the bounce direction, hold the flash head and turn it to the desired angle.

4.4 LCD Display and Controls

The clear LCD panel (5) provides easy access to settings. Use the 4 function buttons and the Select Dial (14) to navigate and adjust parameters.

5. Maintenance

5.1 Cleaning

• Use the provided cleaning cloth to gently wipe the flash body and LCD screen.
• For stubborn dirt, use a soft, damp cloth. Avoid harsh chemicals or abrasive materials.
• Keep the hotshoe contacts clean and dry to ensure proper communication with the camera.

5.2 Battery Care

• Remove batteries when the flash is not in use for extended periods to prevent leakage.
• Use high-quality AA batteries for optimal performance and recycle used batteries responsibly.

5.3 Storage

• Store the flash in a cool, dry place, away from direct sunlight and extreme temperatures.
• Use the protection bag to prevent scratches and dust accumulation.

6. Troubleshooting

If you encounter issues with your GODOX TT350O flash, refer to the following common problems and solutions:

• Flash not firing or inconsistent firing:
  • Check battery levels and ensure they are correctly inserted.
  • Ensure the flash is securely mounted on the camera's hotshoe and the lock ring is tightened.
  • Verify that the flash mode (TTL, M, S1/S2) is appropriate for your shooting setup.
  • If using wireless mode, ensure the master and slave units are on the same channel and group.
• Incorrect exposure (over/underexposed images):
  • In TTL mode, check for flash exposure compensation settings on both the flash and camera.
  • In Manual mode, adjust the flash power output (1/128 to 1/1) using the Select Dial.
  • Ensure the flash head is pointed correctly (e.g., not directly at the subject if bouncing is desired).
• Zoom function stuck at 14mm:
  • Ensure the built-in wide diffuser panel (20) is fully stowed inside the flash body. It should click into place. The flash detects when this panel is deployed and overrides zoom information.
• Flash not recognized by camera:
  • Remove and re-mount the flash on the camera's hotshoe.
  • Clean the hotshoe contacts on both the flash and camera.
  • Ensure the flash firmware is up to date (check GODOX website for updates).
