5. Operation
5.1 Display Overview
The E4 features a clear display showing critical information such as group settings, energy levels, modeling light status, battery level, mode, sync settings, and channel. Familiarize yourself with the display layout for efficient operation.
5.2 Button Functions
The E4 trigger has several buttons for controlling various functions:
- Power Button: Turns the E4 on or off.
- Test Button: Triggers a test flash.
- Group Buttons (A, B, C): Selects and controls individual flash groups.
- Energy Adjustment Buttons (+/-): Adjusts the flash energy output.
- Mode Button: Toggles between TTL and Manual (M) modes.
- Sync Button: Cycles through sync modes (1st curtain, 2nd curtain, HSS).
- Channel/Beeper Button: Short press to switch channels (1-8). Long press to turn the beeper on/off.
- Head Button: Turns the flash head on/off.
- Model Button: Turns the modeling light on/off.
5.3 Modes (TTL, Manual, HSS)
- TTL (Through-The-Lens) Mode: Provides automatic flash exposure by measuring the light through the camera's lens. Ideal for fast-paced shooting where lighting conditions change frequently.
- Manual (M) Mode: Allows precise control over flash power output. Adjust the energy using the +/- buttons for consistent lighting in controlled environments.
- HSS (High-Speed Sync): Enables the use of flash at shutter speeds faster than the camera's native flash sync speed (up to 1/8000s). This is crucial for overpowering ambient light in bright conditions or using wide apertures outdoors.
5.4 Channels and Groups
The E4 supports 8 frequency channels and 3 groups (A, B, C), allowing you to control multiple Profoto flashes independently without interference. This is particularly useful in multi-flash setups or when working in environments with other wireless systems.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the trigger. Avoid using liquid cleaners or solvents.
- Storage: Store the E4 in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if the unit will not be used for an extended period to prevent leakage.
- Hot Shoe Contacts: Keep the hot shoe contacts clean and free from dust or debris to ensure reliable connection with your camera.
7. Troubleshooting
- Trigger Not Firing:
- Check battery level and replace if necessary.
- Ensure the E4 is securely mounted on the camera's hot shoe.
- Verify that the flash units are powered on and set to the correct channel and group as the E4.
- Check camera settings to ensure external flash is enabled.
- Inconsistent Flash Exposure:
- In TTL mode, ensure there are no obstructions between the E4 and the flash units.
- In Manual mode, double-check the power settings on the E4 and the flash units.
- Ensure the camera's ISO, aperture, and shutter speed settings are appropriate for the lighting conditions.
- Limited Range:
- Ensure there are no significant physical obstructions (walls, large objects) between the E4 and the flash units.
- Check for potential sources of 2.4GHz interference in the environment.
- Verify battery levels on both the E4 and flash units.
