Maintenance

Battery Management

Both the keyboard and mouse are equipped with rechargeable batteries. A single charge can provide power for up to 10 days, depending on usage. When the battery level is low, an indicator light will notify you. Recharge the devices using the supplied Micro-USB cable.

• To charge the keyboard: Connect the Micro-USB cable to the charging port on the keyboard and a USB power source.
• To charge the mouse: Connect the Micro-USB cable to the charging port on the mouse and a USB power source.

Cleaning

To clean your devices, use a soft, lint-free cloth. For stubborn dirt, slightly dampen the cloth with water. Avoid using harsh chemicals or abrasive materials.

Troubleshooting

Connectivity Issues

• No Connection: Ensure both the keyboard and mouse are turned on and fully charged. Verify the Logitech Unifying receiver is securely plugged into a USB port. For Bluetooth, ensure your computer's Bluetooth is enabled and the mouse is in pairing mode on an available Easy-Switch channel.
• Interference: If experiencing intermittent connection, try moving the devices closer to the Unifying receiver or computer. Avoid placing the receiver near other wireless devices or large metal objects that may cause interference.
• Logitech Options: If issues persist, open the Logitech Options software. It can often diagnose and suggest solutions for connectivity problems. You can also re-pair devices through the software.

Keyboard Backlighting

• If backlighting is not working, ensure the keyboard is charged. Check the illumination settings in Logitech Options to confirm auto-illumination is enabled.

Mouse Tracking

• If the mouse is not tracking smoothly, ensure the Darkfield Laser sensor on the bottom is clean and free of debris. While it tracks on most surfaces, extreme textures or highly reflective surfaces might affect performance.
