•As a basic guide, the effective distance between the master and remote flash units is up to approximately 10 m (32 ft) in the forward-facing position, and approximately 7 m (22 ft) at both sides. These ranges vary slightly depending on ambient light.

•There is no limit to the number of remote flash units that can be used together. However, when using many remote flash units, light may be unintentionally picked up by the light sensor of the master flash unit and interfere with correct functioning. Therefore, the number of remote flash units used for wireless multiple flash-unit photography should be limited to around 3 for 1 group.

•Place all remote flash units in the same group close together and facing the same direction.
