1 Install Batteries and Check Battery Power Use two CR123A or DL123Atype 3V lithium batteries. Other power sources cannot be used. 1. Open the battery chamber lid and insert batteries with the "+" and "-" ends positioned as marked inside the battery chamber. Then close the battery chamber lid by sliding it into place while pressing it down. • Always use fresh batteries of the same brand. 2. Press the ON/OFF button to turn on the SB-50DX. Confirm that the readylight comes on. • If the ready-light does not light up within 30 sec., change batteries. Note: Storing batteries Keep the batteries out of children's reach. If swallowed, contact a doctor immediately. (For "Notes on batteries", see p. 65). Check point We recommend that you take spare batteries with you, especially when traveling. Test firing 12 You can perform test firing to ensure that the SB-50DX is working properly. Turn the SB-50DX on, confirm that the ready-light comes on, then press the FLASH button to fire the SB-50DX. For test firing, the SB-50DX fires at 1/16 output in TTL/D-TTL auto flash mode (p. 25) or at maximum output in Manual flash mode (p. 31). When performing test firing, never place your eyes near the flash head. • ON/OFF button and standby function • Pressing the ON/OFF button turns on the SB-50DX and indications appear in the LCD panel. Pressing the button again turns off the SB-50DX and indications disappear. • If the SB-50DX is left unused for approx. 40 seconds, the standby function activates and automatically turns it off. In Wireless Flash mode (p. 48), standby function activates in approx. 40 seconds as normal mode when the Speedlight is attached to camera body; however, standby duration is prolonged to approx. one hour when the Speedlight is detached from camera body (used as a slave flash unit, p. 48). • With a camera body that is compatible with TTL/D-TTL auto flash (p. 28), the SB-50DX automatically turns off when the camera's exposure meter turns off. • To reactivate the SB-50DX after it has been automatically turned off by the standby function, press ON/OFF button or FLASH button. (Pressing the FLASH button does not activate flash in this case). With a camera body that is compatible with TTL/D-TTL auto flash, the SB-50DX automatically turns on when the camera's exposure meter turns on. • Standby function cannot be deactivated. Note: Completely turning off the SB-50DX When carrying the SB-50DX in a camera bag, make sure that it is completely turned off. If the SB-50DX has been turned off by the standby function, accidental firing, operation and/or battery drain may occur while it is being carried. To completely turn off the SB-50DX, press the ON/OFF button while the LCD panel is on. Then confirm that the LCD indications are off. • Confirming recycling time and replacing batteries • After firing at its maximum output in Manual flash mode (p. 31), the SB-50DX will take approx. 3.5 sec. to be ready for the next shot (with fresh batteries). • Replace batteries with new ones if the ready-light takes more than 30 sec. to light up after firing. If the ready-light does not light up within 40 sec. after firing, the SB-50DX turns off. • Approximately 260 flashes are available with a fresh set of batteries (in Manual flash mode). 13 Basic Operation
