User manual SIGMA EM-140 DG BROCHURE

[. . . ] Do not use a thinner, Benzene or other cleaning agents to remove dirt or finger prints from the component. For extended storage, choose a cool dry place, preferably with good ventilation. It is recommended that the flash be charged and fired several times a month, to maintain proper capacitor functioning. ) it is also possible to use it with other lens types, however please pay attention to the following points. [. . . ] If you use NiCad batteries, please confirm that the battery contacts touch the battery compartment properly. To prevent battery explosion, leakage or overheating, use four new AA batteries of the same type and brand. Do not disassemble or short-circuit batteries, or expose them fire or water; they may explode. Also, do not recharge the batteries other than Ni-Cd rechargeable batteries. When the flash will not be used for an extended period of time, remove the batteries from the flash, to avoid the possibility of damage from leakage. 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. 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. Fill-Flash TTL BL Center Weighted / Spot Metering cannot use with Spot Fill-Flash F-601M Center Weighted / Spot Fill-Flash If exposure mode is "M", it will be Center TTL BL Weighted/Spot Fill-Flash Center Weighted / Spot Fill-Flash TTL Programmed TTL TTL TTL Programmed TTL TTL TTL It is possible to give the three dimensional effect to your pictures by firing only one side of the flash. 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. it will be beneficial to use a flash meter device for determining the exposure. If the flash output level values of both tubes are the same, the flash output level will be displayed. When the different flash intensity is set, the flash output level will not be displayed on the LCD. You can calculate the correct exposure by using the following formula: Guide Number "GN" / Flash to Subject Distance = F-stop "FV" lock mode allows you to choose exposure for the part of the viewfinder, and lock it in, before taking the picture. intentional exposure compensation of the EM-140 DG NA-iTTL flash's power level Dedicated exclusively to Digital SLR Cameras , F6 , F5 , F4 series , F100 , F90/N90 , F90X/N90S , F80/F80 series , F70D , U/F65/N65 , F801S/N800S , F801/N8008 , F601M , F601/N6006 and Pronea 600i only. Cameras with EV compensation capability allow you to make exposure compensation on either the EM-140 DG NA-iTTL or the camera (or both). If you use both controls, exposure is modified by the sum total of both exposure compensation values, and will affect the background exposure. if your camera is an F601 / N6006 series camera , set the exposure compensation by operating the camera's synchronization mode. [. . . ] By doing so a series of images of the subject will be exposed in one frame. A dark background with a bright subject shows more effectively in this mode. The maximum number of flashes varies, depending on the flash guide number and firing frequency settings. Press the SEL button until the flash firing frequency starts to blink. [. . . ]
