Nikon 4799 F6 Instruction Manual - Page 17

Basic Operation Note on storing batteries Keep the batteries out of children's reach. If swallowed, contact a doctor immediately. (For "Notes on Batteries", x 174.) Backup battery The F6 is equipped with a built-in backup battery for the camera's clock. This charges in approximately 48 hours when 3 V lithium or the optional Multi Power Battery Pack MB-40 (x 166) is supplying power to the F6. When the built-in battery is fully charged, it is able to supply the F6's built-in clock with power for approx. 4 months. When camera's built-in clock has been reset When power is not supplied for a long time or when batteries are installed for the first time and power is turned on, "CLOCK HAS BEEN RESET. Set time and date." may be displayed in the rear LCD panel (the display returns to normal when any of the F6's buttons or Command Dial are used). In this case, set the date and time (x 35). • The camera functions normally without setting the date and time but shooting data cannot be recorded (date and time) (x 112) or imprinted (day/hour/minute, date and time) (x 126) correctly and interval timer (x 140) cannot be executed correctly. • If the camera power switch is turned on after the clock data has been lost, date and time start from 2004, January 1st, 0 hour 0 minute. If date and time are left unset, the clock data will be lost every time the power switch is turned off. For number of film rolls that can be shot with fresh batteries, see page 185. Power source other than 3V lithium batteries Eight AA-type batteries or optional Rechargeable Li-ion Batteries EN-EL4 (with optional Battery Chamber Cover BL-3) can be used to power the F6 with an optional Multi Power Battery Pack MB-40 (x 166) attached. We recommend that you take spare batteries with you, especially when traveling. 17
