Operating Instructions
The AODELAN E4 offers comprehensive control over your Profoto flash system. Here's how to operate its key functions:
1. Mode Selection (TTL / Manual)
Press the MODE button to switch between TTL (Through-The-Lens) and Manual flash modes. TTL mode automatically adjusts flash output for correct exposure, while Manual mode allows precise control over flash power.

2. Sync Mode Selection
Press the SYNC button to cycle through available sync modes:
- First-Curtain Sync: Flash fires at the beginning of the exposure.
- Second-Curtain Sync: Flash fires at the end of the exposure, useful for creating motion blur effects with a sharp trailing image.
- High-Speed Sync (HSS): Allows flash synchronization at shutter speeds faster than the camera's native sync speed, up to 1/8000s. This is ideal for shooting with wide apertures in bright conditions.

3. Group and Channel Control
The E4 supports 3 groups (A, B, C) and 8 channels, allowing precise control over multiple flash units.
- Selecting Groups: Press the A, B, or C buttons to select the desired flash group.
- Adjusting Energy: Use the + and - buttons to adjust the flash power for the selected group. Power ratios can be adjusted from ±3 EV.
- Changing Channels: Press the CHANNEL/♪ button to change the communication channel. Ensure the trigger and flash units are on the same channel.

Troubleshooting
If you encounter issues with your AODELAN E4 Flash Trigger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Trigger does not power on. | Low or dead batteries; incorrect battery installation. | Replace batteries with fresh ones. Ensure batteries are inserted with correct polarity. |
| Flashes do not fire. | Incorrect channel setting; flash units not powered on or in range; trigger not securely mounted; camera settings. | Verify trigger and flash units are on the same channel. Ensure flashes are powered on and within range. Re-mount the trigger securely. Check camera flash settings. |
| TTL mode not working correctly. | Flash units not in TTL mode; environmental factors affecting exposure. | Ensure Profoto flashes are set to AirTTL mode. Adjust flash exposure compensation if needed. |
| HSS not activating. | Camera shutter speed too slow; HSS not selected on trigger. | Ensure camera shutter speed is above its native sync speed. Press the SYNC button on the E4 until HSS is displayed. |
| Limited range or intermittent connection. | Obstructions; interference; low battery. | Reduce distance between trigger and flashes. Minimize obstructions. Check for sources of radio interference. Replace batteries. |
