Nikon SB-102 instruction manual Test Firing, Other Warning Functions

CONTROLS IN DETAIL-continued____

Because of these three factors, the ready-light may blink to indicate that the light output was insufficient for correct exposure even if the subject was within the coupling distance range.

Other Warning Functions:

1.When the shutter speed/mode selector dial of the Nikonos -V is set to M90 (1/90sec.) or B (Bulb), or when the shooting mode selector switch of the flash unit is set to "TTL" when using the Nikonos IV-A.

2.When the sync cord is not securely connected to the Nikonos-V.

3.When the ASAIISO film speed setting dial of the Nikonos-V is set to beyond ASAIISO 400.

1.When the speedlight has recycled.

2.When the ASA/ ISO film speed dial is set to beyond ASA/ISO 400.

3.In the auto mode, the optional Sensor Unit SU-101 is required.

4.Speeds of 1/500 second, 1/250 second, and 1/125 second cannot be used because the sync shutter speed is 1/90 second or slower. c==J = Proper flash synchronization is not possible because the shutter speed/shooting mode is improperly set.

-When the camera is set at M90 or M, the camera's exposure meter will not operate even if the shutter release button is depressed.

Test Firing

To determine whether or not the flash illumination is sufficient for a correct exposure, especially when using the non-TTL automatic mode with distant subjects or when using bounce-flash photography, test-fire the flash unit. To test-fire the SB-102, turn its power switch to "TEST" after the ready-light on the flash unit lights. If the ready-light on the flash unit begins blinking after test-firing , switch to a larger aperture (a numerically smaller f-number), if possible, or move closer to the subject before shooting.

This setting also enables you to repeatedly fire the flash manually with the camera set at B (open-flash firing) to create multiple-exposure stroboscopic effects or "paint" the scene with light. When doing this, discon- nect the speedlight from the camera or the flash unit will not fire , even if its power switch is set at " TEST." (Remove the sync cord and replace the camera'sflash

socket and the flash unit 'ssync socket cover before

entering the water.)

-After test firing or open-flash firing, reset the speedlight's power switch to "ON" or "OFF."

In the TTL mode, the shutter must be released to test-fire the flash unit, but if there is no film in the camera, the ready-light will blink even if the light output was sufficient for correct exposure .

To avoid this, place a strip of cut film (provided it is not too old) or a piece of gray paper under the camera's film pressure plate, then release the shutter.

-Even if two speedlights are connected by the optional Double Sync Cord, only thespeedlight that is being test-fired will fire .
