This camera requires battery power for operation. Always use six 1.5V AA size batteries.

The ISO film speed and number of exposed frames are unchanged if the batteries are replaced.

Keep spare batteries on hand when shooting out doors or while traveling.

Use of the optional Remote Battery Pack 645 and Power Cord 645 is recommended when the camera is to be under the extremely low temperatures.

Replace all the batteries at the same time. Do not mix battery brands, types or old batteries with new.

Remove batteries when not using the camera for long periods of time as the batteries may leak after time.
