Operating Instructions
1. Powering On/Off
Press and hold the power button (usually marked with a circle and a line) to turn the flash on or off. A green indicator light will illuminate when the flash is ready.
2. Adjusting Power Output
The iM30 supports 7-step manual dimming, from 1/64 to 1/1 power. Rotate the power adjustment dial to select the desired output level.

3. Optical Control Modes (S1/S2)
The iM30 features two optical slave modes, S1 and S2, indicated by dedicated lights. These modes allow the flash to be triggered by another flash unit.
- S1 Mode: This is a simple optical slave mode. The iM30 will fire when it detects a flash from a master flash unit. It ignores pre-flashes.
- S2 Mode: This is an intelligent optical slave mode. The iM30 will ignore the first pre-flash from a master flash (often used for TTL metering) and fire on the second, main flash.
To switch between S1 and S2 modes, press the S1/S2 button. The corresponding indicator light will illuminate.
4. Flash Performance
The iM30 provides a guide number of 15 (ISO 100, meters), offering brighter and more natural fill light compared to most built-in camera flashes. It can deliver approximately 230 full-power flashes on a single set of batteries.

Maintenance
- Keep the flash unit clean and dry. Use a soft, dry cloth to wipe the exterior.
- Avoid exposing the flash to extreme temperatures, humidity, or direct sunlight for prolonged periods.
- Remove batteries if the flash will not be used for an extended period to prevent leakage.
- Do not attempt to disassemble or repair the flash unit yourself. Refer to qualified service personnel.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Flash does not power on. | Batteries are dead or incorrectly inserted. | Replace batteries with fresh ones, ensuring correct polarity. |
| Flash does not fire. | Flash not securely mounted; camera not turned on; flash not charged. | Ensure flash is securely mounted and locked. Turn on camera. Wait for flash ready indicator. |
| Flash fires inconsistently in S1/S2 mode. | Interference from other light sources; incorrect mode selected. | Ensure clear line of sight to master flash. Verify S1/S2 mode is appropriate for master flash (e.g., S2 for TTL master). |
| Flash output is too weak/strong. | Incorrect power level selected. | Adjust the power output dial to a higher or lower setting as needed. |
