For details on functions interlocked with the camera, consult your nearest SUNPAK service center or SUNPAK website (http://www. sunpak. com). 9 En Welcome to the worldwide family of Sunpak owners. It is recommended to use the NiMH (Nickel Metal Hydride) batteries in order to decrease the charging time and increase the firing count. Test Firing After the READY lamp lights steadily, press the TEST/ READY button to activate test firing. This allows you to confirm that the flash fires. 11 En TTL Effective Range When the subject is within the TTL effective range, the selected EV adjustment indicator lights for about 3 seconds after firing. If the indicator does not come on, approach the subject or open up the aperture (decrease the f-number) and retry shooting. Changing the ISO speed to a higher sensitivity (higher value) can also be helpful. The effective TTL range is shorter than usual immediately after the READY lamp comes on. again. If the brightness is still insufficient, press the button again so that the "+1" EV adjustment indicator lights up and retry shooting. If the picture is too bright, press the EV ADJUST button to change the lighting EV adjustment indicator in the "-" direction until the desired brightness is obtained. The adjustment with the ED ADJUST button is invalid when no EV adjustment indicator is lit (i. e. when the TTL auto brightness adjustment is not activated). Make sure that one of the EV adjustment indicators is lit before pressing the EV ADJUST button. To exit from the EV adjustment mode, press the EV ADJUST button again. [. . . ] It is therefore recommended to open up the aperture (to decrease the f-number as much as possible). The surface used for bounce lighting should be as white as possible and its reflectivity as high as possible. Note that, in color photography, if the reflecting surface has a color, the colored reflection will stain the subject in that color.
