NiMH batteries may also provide acceptable low temperature performance. To improve the performance of all battery types, keep the camera and/or batteries stored in a warm inside pocket when in a cold environment.

Extending Battery Life

Here are some tips for extending battery life:

•Change the Display Brightness setting in the Setup Menu to Low, so that the Image Display consumes less power when in Live View (see Display Brightness on page 94).

•Minimize the use of flash by setting your camera to Auto Flash, instead of Flash On (see Setting the Flash on page 40).

•Use the optional HP AC power adapter or HP Photosmart M-series dock when the camera will be on for extended periods of time, such as when you transfer images to your computer or when printing.
