Installing New Battery

When you install the battery for your mouse, make sure it faces the correct direction, as shown in the following image:

Extending battery life

Your mouse enters standby mode to conserve power when it's not in use. Here are some other ways you can help extend the battery life:

• Use only alkaline batteries. Non-alkaline batteries (such as NiMH or NiCd) operate at a lower voltage and may affect the battery life.
• Avoid using your mouse on dark or transparent surfaces, such as glass. These surfaces cause the optical sensor to use more power.
• Make sure replacement batteries are new and within the manufacturer's expiration date.
