5. Operating Modes
The Godox TT350 offers various operating modes to suit different photographic needs.

5.2. Manual Flash Mode (M)
In Manual mode, you set the flash output power from 1/1 (full power) to 1/128 in 1/3 EV steps. This provides precise control over lighting.
5.3. Multi Flash Mode
Multi flash (Stroboscopic flash) fires a series of rapid flashes within a single exposure, useful for capturing multiple movements of a subject in one frame.
5.4. High-Speed Sync (HSS)
HSS allows the flash to synchronize with shutter speeds up to 1/8000s, enabling you to use wider apertures in bright conditions or freeze fast motion.

5.5. Wireless 2.4G X System
The integrated 2.4 GHz X radio system allows the TT350 to function as a master or slave unit. It supports 16 channels and three groups (A, B, C) with a range of up to 328 feet (100 meters). This enables versatile multi-flash setups with other Godox X system products.

5.6. Optical Slave Modes (S1/S2)
The TT350 also features optical receiver modes (S1/S2) for working with other standard flashes that do not have a built-in 2.4G system.
6. Maintenance
- Clean the flash unit regularly with a soft, dry cloth.
- Avoid using solvents or harsh chemicals.
- Remove batteries when the unit is not in use for extended periods to prevent leakage.
- Store the flash unit in a cool, dry place, away from direct sunlight and extreme temperatures.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Flash does not fire. | Low battery, incorrect mode, flash not securely mounted. | Replace batteries, check flash mode (TTL/M), ensure secure hot shoe connection. |
| Flash output is too dark/bright. | Incorrect FEC setting, manual power too low/high. | Adjust FEC in TTL mode or manual power in M mode. |
| Wireless triggering fails. | Incorrect channel/group, distance too far, interference. | Verify channel and group settings on both flash and trigger. Reduce distance or change channel. |
| Flash head does not zoom. | Manual zoom selected, zoom motor issue. | Ensure auto zoom is enabled or manually adjust zoom. Contact support if motor is faulty. |
