Thread: Nissin Di622 flash has cyclic humming noise?

    Default Nissin Di622 flash has cyclic humming noise?

    Just bought a Nissin Di622 flash for Nikon.
    Didn't notice the humming sound at the shop as I guess it was too noisy there.

    After powering it up, it has this high pitch humming sound which happens every 3 seconds continually. I tried changing batteries with fresh ones but its still the same. The manual never mentioned a thing about the sound.

    Its a bit like the flash charging sound after a full blast. However, its continuous happening every 3 seconds or so.

    Anyone else know this phenomenon?
