TTL MODE
TTL mode can provide correct exposure for subject, and will control the amount of flash.
Please refer to <<CHART A>>, which shows the combinations of camera and lens types, exposure
mode, and flash modes.
TTL function does not work, in the case of Cameras F3 series, FM10, New FM2, FE10.
1. Set the exposure mode of the camera. (However, depending on the
camera, exposure setting may vary). Please refer to Camera's
Instruction manual.
2. Slide the Flash's power switch to the ON position.
3. Select TTL/BL or TTL by pressing the MODE button.
When you use Digital SLR Camera, please do not fail to select TTL/BL.
CLS compatible models are controlled by i-TTL exposure system. CLS
incompatible models are controlled by D-TTL exposure system. In both
cases, the character " d " (digital) will be displayed on the LCD panel.
In the case of cameras; F6, F5, F4 series, F100, F90X/F90/F80
(N90S/N90/N80) series, F70D/N70, F810S/N8008S, F801/ N8008S
and Pronea 600i. TTL/BL or TTL can be selected. However, Nikon
cameras, other than those on the above list can select only TTL.
4. Focus on the subject.
5. Confirm the Ready Light and press the shutter release button.
When the camera does not receive the appropriate exposure for the subject, the TTL/BL or TTL mark on
the LCD panel will appear for 5 seconds after shooting, which shows that the flash power is not enough
for this situation. Please re-take a closer distance or use a wider aperture.
When the flash is fully charged, the ready light in the camera's viewfinder will appear. If it does not
appear, shutter of the camera may operate at a slow shutter speed without triggering the flash.
