Setup
Follow these steps to set up your Logitech Signature M650 mouse:
- Battery Installation: The mouse comes with a pre-installed AA battery. If you need to replace it, open the battery compartment on the bottom of the mouse (refer to Figure 4) and insert a new AA battery, ensuring correct polarity.
- Power On: Slide the power switch on the bottom of the mouse to the ON position.
- Connection Options:
- Logi Bolt USB Receiver: Remove the Logi Bolt USB receiver from its storage slot inside the battery compartment. Plug the receiver into an available USB port on your computer. The mouse should connect automatically.
- Bluetooth Low Energy: Ensure your device has Bluetooth enabled. Press and hold the connection button on the bottom of the mouse until the LED indicator starts blinking rapidly. On your device, go to Bluetooth settings and select "Logitech M650" from the list of available devices to pair.
- Install Logi Options+ Software (Optional but Recommended): Download and install the Logi Options+ software from the official Logitech website. This software allows you to customize buttons, check battery life, and optimize your mouse experience.
Operating Instructions
The Logitech Signature M650 mouse is designed for intuitive use with advanced features:
- SmartWheel Scrolling: The SmartWheel automatically switches between line-by-line precision and super-fast scrolling. Gently scroll for precise control, or flick the wheel for rapid navigation through long documents or web pages.
- Programmable Buttons: The mouse features 5 programmable buttons. By default, the side buttons may function as forward/back. Using the Logi Options+ software, you can customize these buttons to perform various actions such as copy/paste, media controls, or application-specific functions.
- SilentTouch Technology: Experience a quieter workspace with SilentTouch technology, which reduces click sounds by 90% compared to traditional mice.
- Ergonomic Design: The contoured shape, soft thumb area, and rubber side grips provide enhanced comfort for extended use.
Maintenance
To ensure your Logitech Signature M650 mouse remains in optimal condition:
- Cleaning: Use a soft, lint-free cloth to wipe the surface of the mouse. For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals or abrasive materials.
- Sensor Cleaning: Occasionally, use a cotton swab lightly dampened with isopropyl alcohol to gently clean the optical sensor on the bottom of the mouse.
- Battery Replacement: The included AA battery provides up to two years of battery life. When the battery indicator light on the mouse or in the Logi Options+ software indicates low power, replace the AA battery as described in the Setup section.
