Owner`s manual

Bug Fixes:
• 430EX issues: The original 430EX (I, not II) would sometimes cause over-exposures or “blowouts” when used as a remote
flash on a FlexTT5. Operation appeared erratic. This has been corrected. NOTE: The 430EX is still a very RF noisy flash and
every effort should be made to optimize reception. Please use the mounting suggestions on Page 30 of the Owner’s Manual,
and especially consider using a Canon OC-E3 cable and a ferrite choke.
• 580EX (I and II) Custom Functions: Fixed issue where certain Custom Functions or C.Fn combos caused a remote flash to
not trigger.
• Shutter speed raising then lowering: Previously if you started at a shutter speed faster than 1/500, then went back down
below 1/250 in one step, remote flashes could get out of sync (shutter speeds between 1/250 and 1/500 were not affected).
If the camera went to sleep and woke back up, this usually cleared the problem. On fast sleeping cameras like the 40D, 50D,
Rebel, etc., this issue hardly ever manifested. On cameras that took longer to sleep, like the 1D Mark III, the impact could be
larger. This has been corrected.
• Relay Mode: Fixed issues around Auto-Relay Mode in the FlexTT5 where it would not perform properly when triggered from
a Standard Channel Transmitter. Also corrected situation where a flash in the top shoe of the FlexTT5 might not trigger in relay
mode. Corrected a “lock-up” situation.
• FlexTT5 P2 trigger as transmitter: Previously the FlexTT5 was not triggering P2 when it was being used as a Transmitter.
This would have made a local manual flash connected to that port not usable at the camera position. This has been corrected.
• FlexTT5 TEST response time: When TEST was pressed on a FlexTT5, it could take up to a full second before the connected
or remote radios were triggered. This has been corrected.
• 1Ds Mark III wakeup: In some instances the 1Ds Mark III (and possibly other cameras) when coming out of sleep mode,
would cause odd behavior with the ControlTL radios. This has been corrected.
• Shutter speed limiting: On the 1D Mark III and 5D Mark II, and possibly some other cameras, sometimes shutter speed
would bounce down to X-sync. This has been corrected.
