[. . . ] All information in this Quick Guide is subject to change. UPDATE FIRMWARE: Be sure to upgrade all your PocketWizard ControlTL radios to the latest firmware for proper AC3 functionality. ZoneController Release Button Mode Switches Power Dials Canon-style Hot Shoe (for connecting to a MiniTT1TM or FlexTT5TM for Canon only) Status LED READ ME FIRST: All equipment should be turned OFF when making connections or unwanted triggering or other erratic behavior may occur. The first exposure after making initial connections or powering on may not be properly exposed and flash power levels may not be set as expected. The first exposure is a calibration shot. [. . . ] Power on the transmitter, then the camera. Set up remote Speedlites on FlexTT5 radios normally. Set all Speedlites on remote FlexTT5 radios to normal E-TTL Mode. Do not use Manual or MASTER/SLAVE on your remote Speedlites. The AC3 will use E-TTL commands to control manual power levels when the AC3 zone is set to M. b. Use the FlexTT5 Zone Switch to assign Zone A, B, or C to the Speedlite. 3. On the AC3, set the Mode Switches to M or A for the zones in use. Adjust flash output power with the Power Dials: + = Black numbers on a white background increase flash output by the stops shown. ­ = White numbers on a black background decrease flash output by the stops shown. Take pictures normally. The AC3 ZoneController enhances the ControlTL capabilities of your MiniTT1 and FlexTT5 radios by allowing you to control the flash output power remotely in either Auto/E-TTL or Manual. AC3 Manual Mode: the Power Dial sets the remote Speedlite power output as shown in the table on the right. AC3 Auto Mode: the Power Dial sets the Flash Exposure Compensation (FEC) relative to the E-TTL exposure for that zone. Zones set to Manual or Auto mode can be combined with zones in other modes. Manual zones will not be calculated as part of the E-TTL exposure. / FEC NOTE: Flash Exposure Compensation (FEC) can be set in many places and all values are used together in Auto Mode. FEC can be set: · On the camera for all AC3 zones set to A · On each remote Speedlite · On the AC3 Power Dial when the zone is set to A If the combined FEC adjustments are more or less than your flash's capabilities, then the flash will operate at maximum or minimum output accordingly.
