2. In order to prevent the flash head from overheating and shorten the service life, please do not use the maximum gear (1/1) to flash more than 20 times continuously

Stroboscopic Mode

1. This function is very useful when making flash multiple exposure effects and shooting ghost images of fast-moving subjects

3. Be sure to use a new battery or battery in full electricity and allow the flash to have fully electricity back within two flash operations

S1/S2 Mode

S1: It will trigger the flash synchronously with the first flash of the main flash, and the effect is the same as using the flash trigger. Your master flash should be set to manual flash, you should not use a TTL flash system with pre-flash, and you should not use redeye reduction with multiple flashes

S2: This mode can ignore the pre-flash from other TTL flashes, so it can support the master flash that works in TTL mode. If S1 mode can’t synchronize with your built-in flash, you can try S2 mode

Over Heat Protection
