Recommendations

Verify that your flash units support the same radio protocol or are confirmed compatible before operation. Use stable radio channels and avoid strong radio interference for reliable triggering. When measuring from different positions, allow a brief test trigger sequence to confirm synchronization prior to final exposure readings.
