Troubleshooting

Problem

Solution

The flash isn’t being triggered in
slave mode, or the flash is not
noticeable in the picture.

• Ensure the master flash is within transmission range (approximately

33’/10 m) and that the wireless sensor has a clear line of sight with
the master flash.

• The ambient light may be too high.
• Make sure that the flash is set to the appropriate slave mode.

The bottom of the image looks
dark.

• To fully illuminate your subject when shooting close-up photography,

tilt the flash down to the -15° position. (Page 24)

There’s a whining sound coming
from the flash.

• This is normal and does not indicate a malfunction. When the flash

heats up from continuous use, vibrations inside the unit may cause
this sound. It will dissipate as the unit cools.
