Precautions
On Using the Battery Pack
❑ Do not leave battery packs in temperatures above 140°F (60°C), such as in a car parked in the sun or under direct
sunlight.
❑ Battery life is shorter in a cold environment. This is due to decreased battery efficiency at low temperatures.
❑ Charge battery packs at temperatures between 50°F to 86°F (10°C to 30°C). Lower temperatures require longer charging
time.
❑ Do not charge the battery pack in any way other than as described in this user guide or as designated by Sony in writing.
❑ For your safety, Sony recommends using the genuine Sony battery pack and AC adapter that are provided with this
product. If either of these items need to be replaced during the life of the product, be sure to use a compatible genuine
Sony battery pack or AC adapter. Information about compatible models can be found at the following URLs:
