Introduction
The YONGNUO YN685 Speedlite is a high-performance wireless TTL flash designed for Canon DSLR cameras. It integrates seamlessly with YONGNUO's 622c and 603 wireless systems, offering advanced lighting control and flexibility. This manual provides detailed instructions for setup, operation, maintenance, and troubleshooting to ensure optimal use of your YN685 Speedlite.
Setup
1. Battery Installation
The YN685 Speedlite requires four (4) AA-size batteries (alkaline or Ni-MH recommended). Ensure correct polarity when inserting the batteries into the battery compartment located on the side of the flash unit.
2. Mounting on Camera
- Slide the flash unit onto your Canon DSLR camera's hot shoe mount.
- Tighten the locking knob securely to prevent accidental detachment.
3. Wireless System Setup
The YN685 is compatible with YONGNUO 622c and 603 wireless systems. To use the flash wirelessly, ensure your camera is equipped with a compatible YONGNUO wireless transmitter (e.g., YN622C-TX, YN560-TX, RF605, RF603II, RF603). Refer to your transmitter's manual for specific pairing instructions. The YN685 can receive signals from these transmitters to control flash mode, power, and focal length.
Operating Instructions
1. Power On/Off
Press and hold the power button to turn the flash unit on or off. The LCD display will illuminate upon power-on.
2. Mode Selection
Press the MODE button to cycle through available flash modes:
- TTL (Through-The-Lens): Automatic flash exposure based on camera metering.
- M (Manual): Manually set flash power output.
- Multi (Stroboscopic): Fires a series of rapid flashes during a single exposure.
3. Zoom Adjustment
The flash head supports auto and manual zoom, covering a focal length range of 20-200mm. Use the zoom buttons or dial to adjust the flash coverage to match your lens's focal length. In auto mode, the flash will automatically adjust its zoom based on the camera's lens.
4. High-Speed Sync (HSS)
The YN685 supports high-speed sync up to 1/8000s. This feature allows you to use flash at shutter speeds faster than your camera's native sync speed, useful for freezing motion or overpowering ambient light in bright conditions. Activate HSS through your camera's flash settings or the flash unit's menu, if available.
5. Wireless Control
When used with a compatible YONGNUO wireless transmitter, you can remotely adjust flash parameters such as mode, power, and zoom for individual flash groups. This is particularly useful in multi-flash setups.
6. Voice Prompt
The YN685 features a voice prompt function to provide audible feedback on flash status and settings. This feature can be enabled or disabled in the flash's custom function settings.
Maintenance
1. Cleaning
To clean the flash unit, use a soft, dry cloth. For stubborn dirt, a slightly damp cloth can be used, followed by immediate drying. Avoid using solvents or abrasive cleaners, as these can damage the flash's surface or internal components.
2. Storage
When not in use for extended periods, remove the batteries to prevent leakage. Store the flash in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided protective case for added protection.
Troubleshooting
- Flash not firing: Check battery levels. Ensure the flash is securely mounted on the camera's hot shoe or properly connected wirelessly. Verify camera and flash settings are compatible.
- Incorrect exposure: Adjust flash power settings (in Manual mode) or check camera's exposure compensation (in TTL mode). Ensure flash zoom matches lens focal length.
- Slow recycle time: Replace batteries with fresh ones or use an external power pack (if supported). Ni-MH batteries generally offer faster recycle times than alkaline.
- Wireless communication issues: Ensure both flash and transmitter are set to the same channel and group. Check for obstructions between the units. Verify battery levels in both devices.
