[. . . ] To remove, turn the locking ring in the opposite direction and slide the adapter off. Connect the QTTL plug to Qflash. 3. 0 General Operation 3. 1 Ready light Flash readiness is established when the "Rdy" indicator appears in the Qflash display. If flash ready is supported by the camera, then an LED or flash symbol will appear in the viewfinder when the flash is ready. 3. 2 Shutter speed control If flash readiness is achieved, the camera's automatic system switches the shutter speed to the flash sync speed. [. . . ] 4. 2 "Auto" mode (Qflash T, T2, X, X2): Set the aperture and the film speed the same for both Qflash and the camera. The QTTL adapter will function as a sync cord. Fill" mode (Qflash T2D and X2D:) The "Auto Full" mode useful for any camera that does not support TTL ratio control. Auto Fill is also useful when you prefer the flash control the exposure instead of a camera's own TTL or digital cameras' pre-flash metering. Many photographers find that with digital cameras exposures are more consistent with the Auto Fill mode. Auto Fill is also the method of controlling exposures of remote Qflashes using FREEXWIRE for wireless exposure control. In Auto Fill mode aperture and film speed information come from the camera and cannot be changed on Qflash. Fill flash ratio may be set using the " Fill" switch on the QTTL adapter. Choose any setting from ­3 stops below the camera's aperture to +2 stops above the cameras aperture, in 1/3 stop increments. Light output is controlled by Qflash which will display an indication if the setting is out of the range of the flash. The error indications are: "ERROR ­ Decrease fill flash or F#" For example, the camera is set to F16 and QTTL fill flash is set to +2 stops. Either decrease the F# on the camera or decrease the fill flash ratio on the QTTL adapter. "ERROR ­ Increase fill flash or F#" For example, the camera is set to F4. 0 and QTTL fill flash is set to ­3 stops. Increase the F# on the camera or increase the fill flash ratio on the QTTL adapter. 4. 4 "TTL" mode (Qflash T, T2, X, and X2): Set Qflash to "TTL" mode. Fill flash amount is set by using the " Fill" switch located on the top of the adapter. You may choose a setting from ­3 stops below the cameras aperture to +2 stops above the cameras aperture in 1/3 stop increments. Light output is controlled by the sensor in the camera. Set the film speed on the camera, then refer to the table below.

COM Notes: 1) Qflash T, T2, X and X2 do not support the error messages described in Section 4. 3. 2) Some cameras may not perform TTL flash control in some operating modes. [. . . ] Connect the on-camera Qflash T2D or X2D to the QTTL Adapter with an FW31 Accessory Cord. Set the on-camera Qflash to A. Fill (Auto-Fill) mode. Connect a FREEXWIRE to the remote Qflash (T, T2, T2D, X, X2, or X2D) set to TTL mode. Due to the nature of Pre-flash metering, the camera can effectively control only the output of an on-camera flash. [. . . ]
