•As a basic guide, the effective shooting distance between the master and remote flash units is approx. 10m (33 ft.) or less in the front position, and approx. 5 to 7m (16 to 23 ft.) at both sides. These ranges vary slightly depending on the ambient light.
•Be sure to place all remote flash units that are set in the same group close together.

vSetting up the master and remote flash units
•In most cases, position the remote flash unit(s) closer to the subject than the camera, so that light from the master flash unit can reach the light sensor of the remote flash unit(s). This is particularly necessary when holding a remote flash unit in your hand.
•Data communication cannot be performed properly if there is an obstacle between the master unit and remote flash units.
•Take care not to let light from the remote flash unit enter the camera lens directly or indirectly in TTL auto flash mode. Also, prevent light from entering the master flash unit’s light sensor in
•There is no limit to the number of remote flash units that can be used together. However, if too much light from other remote flash units enters the light sensor of the master flash unit, correct operation may be impossible. Practically, the number of remote flash units in Advanced Wireless Lighting should be limited to three for one group.
•Use the provided Speedlight Stand
•Be sure to perform test firing after setting up all flash units (p. 20).
