Note: For best results, a handheld light meter is recommended when using the manual ash mode.
Important! To avoid overheating and damaging your ash unit, please wait for at least 10 minutes after 20

Controlling Flash Coverage (Zoom)
The VS-570OP’s angle of coverage can be adjusted (“zoomed”) to match the focal length of your lens, so that
your image is evenly illuminated from edge to edge.
When the ash zoom setting is adjusted, the position of the reectors inside the ash head shift in order to
make the angle of coverage wider or narrower.
The available zoom positions are 24mm, 28mm, 35mm, 50mm, 70mm, 85mm, and 105mm.
