• The wireless sensors are located on the front of the VS-570OP. Make sure that sensor is facing the master
ash and that there is no obstruction between the two units.
• When photographing outdoors or in bright ambient light, the sensors can be overwhelmed by ambient light,
which will lower their sensitivity.
• To avoid creating interference between ash units, using more than three in a single group is
not recommended.
