Owner`s manual
NOTE: 
We recently released the latest ofcial ControlTL
®
 rmware, version 5.10. Based on continued internal 
testing and feedback from users, it appears that a couple of the exposure and timing data tables became 
corrupted somewhere in the process. We’ve had reports of improper exposures with several camera models 
as well as clipping with the 1Ds Mark III and 1D Mark IV. We have corrected the tables and reloaded the 
rmware as version 5.150, which can be downloaded via the PocketWizard Utility. 
We recommend upgrading to 5.150 as soon as you can for proper functionality of your MiniTT1 and 
FlexTT5 for Canon.
5.150 Overview 
ControlTL Firmware Version 5.150, the current rmware upgrade for the MiniTT1 Transmitter and FlexTT5 
Transceiver for Canon, now offers compatibility with the AC3 ZoneController. The AC3 ZoneController for 
Canon gives the photographer control over three independent zones of light, whether working in E-TTL or 
Manual mode, directly from the camera’s position. 
This new rmware also adds compatibility with the Canon Rebel T2i and compatibility with the Canon 7D 
and 1D Mark IV has been expanded. 
IMPORTANT:
Always perform a factory reset after updating your rmware. And be sure to write down any custom settings 
for Conguration 1 or Conguration 2 before you reset your radios so you can re-apply them after the 
upgrade. See RESET B on page 28 in the original Owner’s Manual or simply hold TEST as you power on for 
10 seconds until you see 4 blinks (green).
When upgrading your radios, be sure to upgrade all MiniTT1’s and FlexTT5’s to v5.150, because your radios 
will only operate as expected when all units are using the latest rmware.
