Extending battery life
Although your MK545 keyboard and mouse have a standby mode to conserve power when not in use, there are other ways you can help extend the battery duration of your devices.

• Avoid using your mouse on dark or transparent surfaces such as glass. These surfaces cause the optical sensor to use more power.
• Use only alkaline batteries. Non-alkaline batteries, such as NiMH or NiCd, operate at a lower voltage and may negatively impact your battery life.

Installing new batteries
Install the batteries for your mouse, making sure the batteries face the correct direction as shown:
