5.3 Flash Modes and Settings

The trigger supports multiple flash modes for versatile shooting:

• TTL Automatic Flash: Provides automatic flash exposure by measuring the light through the lens.
• Manual Flash (M): Allows precise control over flash output, adjustable from 1/128 to 1/1.
• TCM Conversion (TTL to Manual): This unique feature allows you to convert TTL shooting values directly into Manual output values, combining the efficiency of TTL with the precision of manual control.
• Stroboscopic Flash: Used for capturing multiple exposures of a moving subject in a single frame.
• S1/S2 Optical Slave Mode: Available only in Manual Mode, this allows the trigger to fire other flashes wirelessly when it detects a flash from another unit.

Note: Ensure to disable the single contact mode when operating in TTL and Strobe modes.

5.4 Exposure Compensation (FEC)

Adjust the flash exposure compensation by ±3 EV in 1/3 EV increments to fine-tune your flash output.

5.5 ZOOM Setting

The flash trigger allows you to adjust the flash zoom from 20mm to 200mm. This can be set manually or automatically to match the focal length of your camera lens, ensuring optimal light coverage.

5.6 Wireless Q System Control

The NEEWER QZ-S features a built-in 2.4G wireless Q system for reliable remote control of compatible NEEWER Q system flashes. This includes models such as Z2PRO-S, Z2II-S, Z2-S, Z1-S, Z880-S, NW760-S, S101-400W Pro, S102-400W Pro, Q4, Q6, Q300, and Q200 (off-camera triggering only).

• Channel Scanning: Utilize the channel scanning function to detect available idle channels, which helps minimize signal interference in busy environments.
• Group Control: The system supports control over 5 groups across 32 channels with Wireless ID Groups (OFF, 01-99).
• Transmission Range: The effective transmission range is up to 0-100m (328 feet).

The single point triggering mechanism ensures accurate and responsive flash firing with minimal lag.

6. Maintenance and Care

• Cleaning: Use a soft, dry, lint-free cloth to clean the exterior of the flash trigger and the touchscreen. Avoid using harsh chemicals, solvents, or abrasive materials, as these can damage the finish or screen.
• Storage: When not in use, store the flash trigger in its provided storage case. Keep it in a cool, dry place, away from direct sunlight, high humidity, and extreme temperatures.
• Battery Care: To prolong the lifespan of the built-in lithium battery, avoid fully discharging it frequently. It is recommended to charge the battery regularly, even if the device is not in active use, to maintain its health.
• Firmware Updates: Regularly check for and install available firmware updates from the official NEEWER website. These updates can improve performance, add new features, and enhance compatibility.
• Avoid Impact: Protect the device from drops, impacts, and strong vibrations, which can damage internal components or the screen.

7. Troubleshooting

If you encounter issues with your NEEWER QZ-S Flash Trigger, please refer to the following common problems and solutions:

7.1 Trigger Not Firing or Inconsistent Firing

• Battery Level: Ensure both the flash trigger and the connected flash unit have sufficient battery power. Recharge if necessary.
• Secure Connection: Verify that the flash trigger is securely mounted on your camera's hot shoe.
• Channel and Group Settings: Confirm that the flash trigger and all remote flash units are set to the same channel and group.
• Mode Compatibility: If using TTL or Strobe modes, ensure that the single contact mode is disabled on the trigger.
• Camera Settings: Check your camera's external flash settings to ensure it's configured correctly to work with an external trigger.

7.2 Inconsistent Flash Exposure

• Exposure Compensation (FEC): Review your FEC settings on the trigger and adjust as needed.
• Flash Mode: Ensure the selected flash mode (TTL or Manual) is appropriate for your shooting environment and desired outcome.
• ZOOM Setting: Verify that the flash's ZOOM setting matches your lens's focal length for optimal light coverage.

7.3 Wireless Interference

• Change Channel/ID: Use the channel scanning function on the trigger to find an idle channel with less interference. Adjust the Wireless ID Groups if necessary.
• Range: Ensure the trigger and flash units are within the effective 0-100m transmission range. Obstacles can reduce this range.

7.4 Compatibility Issues

• Camera Compatibility: This trigger is designed for Sony, Canon, Nikon, and Fujifilm cameras. Verify your specific camera model is supported.
• Flash Compatibility: For non-NEEWER Q system flashes (e.g., Yangnuo YN560), ensure they are compatible with the NEEWER Q system or can be triggered via optical slave mode (S1/S2). A NEEWER QR receiver and 2.5mm sync cord (sold separately) may be required for broader compatibility.

8. User Tips

• Verify Camera Compatibility: Always double-check that the flash trigger is compatible with your specific camera model (Sony, Canon, Nikon, Fujifilm) before use to ensure full functionality.
• Monitor Battery Status: Keep a close watch on the 3-bar battery icon displayed on the OLED screen. This helps you anticipate when a recharge is needed and avoid interruptions during critical shooting moments.
• Leverage TCM Mode: The TCM (TTL to Manual) conversion feature is a powerful tool. It allows for a quick transition from the convenience of automatic TTL exposure to the precise, repeatable control of manual settings, which can be invaluable in fast-paced or studio environments.
