[. . . ] battery performance decreases at low temperatures. Keep batteries insulated when using the flash in cold weather. As with any flash, it is recommended you carry spare batteries when on a long trip, or when photographing outdoors in cold weather. Be sure to set the Power Switch to the off position then slide, the battery cover in the direction of the arrow to open. Insert four AA size batteries into the battery chamber. Be sure the + and ­ ends of the batteries are aligned according to the diagram in the chamber. After few seconds, the Ready Lamp will light, indicating that the flash unit can be fired. Please press the "Test Button" to be sure that the flash is working properly. To conserve battery power, the flash unit automatically turns itself off when the flash is not used within approximately 90seconds. To turn the flash on again, depress the "TEST" button or the camera shutter button, halfway. Please note that, "Auto Power Off" mechanism does not work with wireless TTL flash mode, normal slave flash, and designated slave flash modes.

After shooting please press SEL button and then the + or button. By doing this flash unit will be set to default mode, display will show both sides. To prevent overheating of the flash's circuitry, please do not use your Flash unit for at least 10minutes after using the number of flash exposures, shown in the below table have been made in quick succession. The shooting in Manual Mode requires a very advanced technique. When using Manual Flash photography, first take some test shots. [. . . ] When you photograph a moving subject with slow synchronization, usually the furrow of the subject will be exposed in front of the subject. The ordinary flash light will fire when the first shutter curtain is fully opened, thus the subject will be exposed from the time flash is fired to the time the shutter is closed (This is front curtain synchronization). When you use rear curtain synchronization, the flash will fire just before the rear curtain begins to close, and the subject will be exposed by ambient light from the time the shutter opens until the flash fires. As a result, the furrow of the subject will therefore be recorded behind the subject, creating a more natural effect. [. . . ]
