6. Operating Instructions

6.1 Powering On/Off

• To turn on the flash, slide the OFF/ON switch on the rear of the control unit to the ON position.
• The READY indicator light will illuminate when the flash is charged and ready to fire.
• To turn off the flash, slide the OFF/ON switch to the OFF position.

6.2 Automatic TTL Flash Control

The DAF-14 Ring Flash features fully automatic TTL (Through-The-Lens) flash control. This means the flash output is automatically adjusted by your camera to achieve optimal exposure. Simply set your camera to a compatible flash mode (e.g., Program, Aperture-priority, Shutter-priority, or Manual with flash enabled) and the flash will synchronize with the camera's metering system.

• Guide Number: 14 (at ISO 100, 105mm equivalent).
• Automatic TTL Range: The effective range for automatic TTL operation is approximately 0.9 to 7 meters (3.0 to 23.0 feet).
• Auto Exposure Confirmation: The flash system provides confirmation when correct exposure has been achieved. Refer to your camera's manual for specific indicators.

6.3 Taking Photographs

1. Ensure the flash is securely mounted and powered on, and the READY light is illuminated.
2. Set your camera to the desired shooting mode. For macro photography, Aperture-priority mode (A/Av) is often recommended to control depth of field.
3. Focus on your subject. The camera's autofocus system will typically work with the flash.
4. Press the shutter button halfway to allow the camera to meter and the flash to pre-flash (if applicable for TTL).
5. Press the shutter button fully to take the picture. The flash will fire automatically.

7. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior of the flash unit. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Do not use solvents or abrasive cleaners.
• Lens Cleaning: The front of the ring flash head can be cleaned with a lens cleaning cloth and solution, similar to a camera lens.
• Battery Care: Remove batteries if the flash will not be used for an extended period to prevent leakage. Store batteries in a cool, dry place.
• Storage: Store the flash unit in a dry, dust-free environment, away from extreme temperatures.

8. Troubleshooting

If you encounter issues with your DAF-14 Ring Flash, please refer to the following common problems and solutions:

• Flash does not fire:
  • Ensure the flash is turned ON.
  • Check if the READY light is illuminated. If not, the batteries may be low or incorrectly inserted. Replace batteries or check polarity.
  • Verify the flash is securely mounted to the camera's hot shoe and the locking wheel is tightened.
  • Check camera settings to ensure flash is enabled and in a compatible mode.
• Photos are too dark (underexposed):
  • The subject may be outside the effective TTL range (0.9 to 7 meters). Move closer to the subject.
  • Batteries may be low, affecting flash power. Replace with fresh batteries.
  • Check camera's ISO setting. A higher ISO can help in low light conditions.
  • Ensure the lens aperture is not too small (high f-number), which limits light reaching the sensor.
• Photos are too bright (overexposed):
  • The subject may be too close to the flash. Increase distance or use flash exposure compensation on your camera if available.
  • Check camera's ISO setting. A lower ISO can help reduce overall brightness.
• Inconsistent flash firing or power:
  • This can sometimes be caused by loose battery contacts. Ensure batteries are firmly seated.
  • Clean the hot shoe contacts on both the flash and the camera with a clean, dry cloth.
  • If the issue persists, batteries may be faulty or nearing end-of-life. Try a new set of high-quality batteries.

If these steps do not resolve the issue, please contact DÖRR customer support.
