Maintenance
To ensure optimal performance and longevity of your Logitech Wireless Mouse M190:
- Battery Replacement: The mouse uses one AA battery. When performance degrades or the mouse stops responding, replace the battery. The typical battery life is up to 18 months, depending on usage.
- Cleaning: Use a soft, dry, or slightly damp cloth to clean the exterior of the mouse. Avoid using harsh chemicals or abrasive cleaners. For the optical sensor, use a cotton swab to gently remove any dust or debris.
- Storage: When not in use for extended periods, you may remove the battery to prevent potential leakage, although the mouse's power-saving features are designed to minimize power consumption.
Troubleshooting
If you encounter issues with your Logitech Wireless Mouse M190, try the following solutions:
- Mouse Not Responding:
- Check the battery: Ensure the AA battery is correctly inserted and has sufficient charge. Replace the battery if it is weak or depleted.
- Check the USB receiver: Ensure the USB receiver is securely plugged into a working USB port on your computer. Try plugging it into a different USB port.
- Restart your computer: Sometimes a simple restart can resolve connectivity issues.
- Lag or Intermittent Connection:
- Reduce distance: Ensure the mouse is within the 10-meter operating range of the USB receiver.
- Remove obstructions: Large metal objects or other electronic devices can interfere with the wireless signal. Try moving the mouse closer to the receiver or clearing obstructions.
- Avoid interference: Other wireless devices operating on the 2.4 GHz frequency (like Wi-Fi routers or cordless phones) can cause interference. Try to minimize their proximity.
- Cursor Movement is Erratic:
- Clean the optical sensor: Dust or debris on the optical sensor can affect tracking. Gently clean the sensor on the underside of the mouse with a cotton swab.
- Change surface: The mouse may not track well on highly reflective, transparent, or uneven surfaces. Try using a mouse pad or a different surface.
