Camera Setup

After attaching the AS-E900 adapter, turn the flash to the ON position and set the flash mode to TTL. The flash should not be set to the stand-by mode (i.e., STBY); otherwise, it may turn off unexpectedly. If it is possible, the illumination angle should be set to 28mm or wider.

Now you have two choices. You can either allow the external flash (or both flashes) to fire. Or, you can turn off the internal flash and only use the external one. To turn off (i.e., disable) the internal flash, follow the procedure below:

• Turn the Mode Dial to M-REC.
• Press the MENU button twice to bring up the USER SETTING menu as shown in the left image below. Then, use the up and down arrow of the multi-selector to go down and highlight the flash icon. See the right image below.
• This brings us to the SPEEDLIGHT OPT. menu. Use the right arrow of the multi-selector to select SPEEDLIGHT OPT. Then, two options appear as shown in the left image below. The first option, Variable Power, has been discussed in 990's internal flash page (i.e., Using Variable Power). The second one, Speedlight Cntrl is for turning the external flash on or off. Use the down arrow of the multi-selector to highlight Speedlight Cntrl as shown in the right image below.

• Use the right arrow of the multi-selector to select Speedlight Cntrl. Two more options appear as shown in the left image below. These two options are Int & Ext Active and Int Flash Off. If the first option is selected, the internal and external flashes will both be active. In other word, the internal flash may fire in case illumination is insufficient. The second option simply turns off the internal flash. Because we want to turn off the internal flash, use the right arrow of the multi-selector to highlight the second option as shown in the right image below, followed by the right arrow to make a selection.

• Once the above steps complete, press the MENU to return to the M-REC shooting mode.

  Note that once this option is chosen, it will stay there even after turning off the camera. Therefore, you need to go through the above procedure again to reverse the setting..

To enable the internal flash, follow the above procedure to select the Int & Ext Active option.

External Flash Settings

Similar to internal flash, there are five different external flash settings available. Each flash setting is indicated by special icons shown on both the control panel and LCD monitor. The meaning of each flash setting is shown in the table below. Please note that the internal flash icon means Flash Cancel because it has been turned off. If the internal flash is not turned off, the icons shown on the control panel and LCD monitor display only the status of the internal flash.

Icon		Meaning
