VIII. Possible problems during use and solutions
1. Please note when using the flash outdoors: When outdoors, please avoid direct
sunlight on to the wireless triggering sensor to ensure normal function of the S1/S2
modes of the flash light.
2. Precaution for outdoor use with lighting umbrellas/modifiers: Lighting umbrellas/
modifiers are easily blown over and if mounted with the flash light it is possible to
break the hot shoe foot. Take good precautions to avoid being blown over or knocked
over. Please fix to a suitably secure mounting system or avoid outdoor use.
3. Photos are under exposed or over exposed? Check you have not set the shutter speed,
aperture and ISO too near the flash limits of the camera, or, if you have used other
settings including exposure compensation in relation to flash photography, that they are
properly set.
4. Vignetting appears in photos or only part of the subject is illuminated? Please check
the current light coverage of the set zoom focal length and make sure that the camera
lens focal length exceeds the coverage range of the flash. The product’s zooming range
is 24~105mm in the medium format system. You can try to pull out the wide-angle
diffuser to expand the flash range.
