3. Operating Instructions

3.1 Power On/Off

Press and hold the power button on the main control unit to turn the flash on or off. The LCD display will illuminate upon power-on.

3.2 Flash Modes (TTL, M)

Press the MODE button to cycle through available flash modes:

• TTL Mode: (Through-The-Lens) The flash automatically determines the appropriate light output based on the camera's metering system. This is the recommended mode for most users.
• M Mode: (Manual) Allows you to manually set the flash output power. Use the control dial to adjust the power level.

3.3 Flash Ratio Adjustment (A:B)

In TTL mode, you can adjust the flash ratio between the two flash tubes (A and B) to create specific lighting effects. Press the RATIO button and use the control dial to set the desired ratio (e.g., 8:1, 4:1, 1:1, 1:4, 1:8). This allows for emphasizing one side of the subject over the other.

3.4 E-TTL Functions

The YN24EX supports various E-TTL functions accessible through your Canon camera's menu:

• FEC (Flash Exposure Compensation): Adjusts the flash output to fine-tune exposure.
• FEB (Flash Exposure Bracketing): Takes multiple shots at different flash exposure levels.
• Front/Rear-curtain Sync: Synchronizes the flash with the beginning or end of the shutter exposure.
• FE Lock (Flash Exposure Lock): Locks the flash exposure for recomposing.
• Modeling Light: Emits a continuous light to preview the lighting effect before taking the shot.

3.5 LED Focus Assist Light

The built-in LED focus assist light helps achieve precise focus in low-light conditions. Press the L·LED·R button to activate and cycle between low light and highlight modes. This feature is particularly useful for macro photography where focusing can be challenging.

3.6 Sound Prompt System

The YN24EX features a sound prompt system that provides audible feedback for various operations (e.g., recycle complete). This allows you to focus on shooting without constantly checking the display. To enable or disable the sound, refer to the specific instructions in the full user manual or the device's menu.

The unit is equipped with a standard PC synchronous interface. This allows for wired synchronization with cameras or triggers that support a PC sync port, offering an alternative to hot shoe mounting for flash triggering.

The YN24EX automatically saves your last used settings. This ensures that your preferred configurations are retained even after the unit is powered off and on, streamlining your workflow.

4. Maintenance

4.1 Cleaning

To maintain optimal performance, regularly clean the flash unit. Use a soft, dry cloth to wipe the exterior. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Avoid using strong solvents or abrasive cleaners.

4.2 Battery Care

• Remove batteries if the flash will not be used for an extended period to prevent leakage.
• Use high-quality AA alkaline or Ni-MH rechargeable batteries.
• Ensure correct battery polarity during installation.

4.3 Storage

Store the YN24EX in a cool, dry place, away from direct sunlight and extreme temperatures. Use the provided protective nylon bag to prevent dust and scratches.

5. Troubleshooting

If you encounter issues with your YN24EX, consider the following common solutions:

• Flash not firing: Check battery levels. Ensure the flash is securely mounted to the camera's hot shoe. Verify camera and flash settings are compatible (e.g., flash enabled in camera menu).
• Incorrect exposure: Adjust FEC (Flash Exposure Compensation) in your camera menu or flash settings. Ensure flash mode (TTL/M) is appropriate for your shooting conditions. Check flash ratio settings.
• Slow recycle time: Replace old batteries with fresh ones or fully charge rechargeable batteries.
• Flash heads not working: Ensure cables are securely connected to the main unit and flash heads.
