- S2 Mode: The flash will ignore a single pre-flash from a master unit and fire in response to the main flash. This is suitable for TTL flash systems that emit a pre-flash for exposure measurement.
5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your GODOX QS600II Studio Strobe Flash Light.
