[. . . ] When upgrading your radios, be sure to upgrade all MiniTT1's and FlexTT5's to v5. 200, because your radios will only operate as expected when all units are using the latest firmware. Compatibility: - PowerST4 for Elinchrom RX and AC9 AlienBees Adapter Many improvements have been made in preparation for the launch of these ControlTL devices. Review the Quick Guides for both the PowerST4 and the AC9 AlienBees Adapter to learn more about their PowerTracking features. - Nissin Flash models Di866 and Di622 A control was added to the Misc Tab called "Top Shoe Detection Mode. " To use a Nissin Di866 or Di622 for Canon this control must be set for "Nissin Flash. " Most features of this flash are supported. www. PocketWizard. com info@pocketwizard. com 2 Improvements: - Improved high ambient temperature operation - Learn Mode has been greatly improved. Teaching from a MiniTT1 or FlexTT5 as a transmitter now results in the ControlTL channel being learned very reliably. IMPORTANT: Learn Mode is not required for normal operation of your radios. It is intended as a tool for resolving channel conflicts in the field. If you wish to operate on different channels, then the PocketWizard Utility is the recommended method for setting channels. - Radio transmission reliability of the MiniTT1 when there is a flash or accessory in the top shoe has been improved. - Improved Relay Mode operation when triggering a remote camera that is using a Rear Curtain Sync shutter speed.
