Lithium Batteries
•The performance of lithium batteries is severely reduced at low temperatures. Consequently, you may only be able to take a few pictures, even with a brand new 2CR5 lithium battery. To improve the performance at low temperatures, warm the battery in your pocket before using it in the camera. It is also advisable to shut off the LCD monitor and use the optical viewfinder to compose images at temperatures close to 32˚F (0˚C).
•A lithium battery that appears to have lost its charge at cold temperatures may still be usable at room temperature.
•Do not use a lithium battery that has been used in another camera. A malfunction may result.
