Operating Instructions
Flash Modes
The NEEWER Q4 supports three primary flash modes:
- TTL (Through-The-Lens): Automatic flash mode compatible with Canon E-TTL II, Nikon i-TTL, and Sony TTL systems. This mode provides accurate exposure automatically and supports Flash Exposure Compensation.
- Manual (M): Allows manual control over flash power output, modeling light, and first/second curtain sync.
- Multi (Stroboscopic): Controls the stroboscopic rate, allowing up to 100 flashes at 199 Hz for capturing multiple exposures in a single frame.

High Speed Sync (HSS)
The Q4 supports 1/8000s High Speed Sync, allowing you to synchronize the flash with fast shutter speeds. This is particularly useful for overpowering ambient light in bright outdoor environments.

Wireless Control with NEEWER 2.4G Q System
The Q4 features a built-in NEEWER 2.4G Q System, allowing it to receive signals from a master trigger (e.g., QPRO-C/N/S Wireless Flash Trigger, not included) for effortless wireless multiple flash shooting. It supports 5 groups (A, B, C, D, E) and 32 channels (1-32), with IDs from 01-99.

Custom Settings (C.Fn) and Firmware Upgrades
The Q4 supports C.Fn custom settings for personalized operation. It also supports USB Type-C firmware upgrades to ensure your unit is always up-to-date with the latest features and improvements.
Important: Disable Single Contact Mode for TTL and High Speed Sync functionality. Single Contact Mode only emits a flash signal and does not support other functions. It is primarily for M/Multi mode continuous shooting.

Modeling Lamp

Flash Duration and Recycling Time
The flash offers a duration of 1/209-1/10989s, allowing for freezing fast-moving subjects. The recycling time is between 0.01-1.2 seconds, enabling rapid continuous shooting.

Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the flash unit and softbox. Avoid using abrasive cleaners or solvents.

- Battery Care: Do not overcharge or completely discharge the lithium battery. If storing for extended periods, charge the battery every 3-6 months to maintain its health.
- Flash Tube: Handle the flash tube with care. Ensure it is properly plugged in before operating the flash to prevent damage.
