Installing new batteries

When you install new batteries, make sure they are facing the correct direction as shown:

Extending battery life

Your mouse enters standby mode to conserve power when not in use. For best battery performance:

• Use only alkaline batteries. Non-alkaline batteries (such as NiMHor 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.
• Don't mix old and new batteries.
