[. . . ] Thank you for purchasing a Canon product. Speedlite Transmitter ST-E2 is a wireless transmitt e r which can control up to two Speedlite 550EX groups set as slaves. The transmitting range is about 12 to 1 5 meters / 39. 4 to 49. 2 ft indoors and 8 to 10 meters / 26. 2 to 32. 8 ft outdoors. With Type A cameras (EOS-3, EOS Elan IIIIIE, EOS 50/50E, EOS 500NlRebel G, EOS IX. EOS IX7AX Lite), the ST-E2 can execute the following operations through wireless control: E-?"rL autoflash High-speed sync (FP flash) FE lock Flash exposure compensation Manual flash (Flash output set with Speedlite) Multi-flash firing (Set with the Speedlites) This Instructions booklet assume t h a t a Type A camera is used with the ST-E2.

The slave's AF-assist beam is not emitted (except when t h e flash is ready).

When t h e correct flash exposure is obtained, t h e ST-E2's flash confirmation lamp lights for about 3 sec. If i t does not light, the picture might be underexposed.
