About Slave Group Control
Do not fire the modeling flash more than 10 consecutive times. If you fire the 
modeling flash 10 consecutive times, allow the Speedlite to rest for at least 
10 min. to avoid overheating and deteriorating the flash head.
The modeling flash cannot be fired with the EOS 300/REBEL 2000 and 
Type-B cameras (p.2).
