Operating Instructions

This keyboard functions as a standard laptop keyboard with additional features specific to the Swiss (SW) layout and integrated backlighting.

Key Functions:

• Standard Alphanumeric Keys: Used for typing letters, numbers, and symbols.
• Function Keys (F1-F12): These keys often have secondary functions (e.g., volume control, screen brightness, Wi-Fi toggle) when pressed in combination with the Fn key. Refer to your laptop's specific documentation for exact Fn key combinations.
• Backlight Control: The keyboard features integrated backlighting. Typically, the backlight can be toggled on/off or adjusted in brightness using a specific Fn key combination (e.g., Fn + Fx, where Fx is a function key with a backlight icon). Locate the key with a backlight symbol (often resembling a sun or light bulb) to control this feature.
• Swiss (SW) Layout Specifics: This keyboard includes characters and symbols specific to the Swiss layout, such as '§', '€', 'é', 'à', 'ö', 'ä', 'ü', and '£'. Familiarize yourself with the placement of these characters.
• Navigation Keys: Includes Home, End, PgUp (Page Up), PgDn (Page Down), and arrow keys for document navigation.

Maintenance

Proper maintenance can extend the lifespan of your keyboard and ensure optimal performance.

• Cleaning: Regularly clean the keyboard surface with a soft, lint-free cloth slightly dampened with water or a mild, non-abrasive cleaning solution. Avoid spraying liquids directly onto the keyboard.
• Dust Removal: Use compressed air to remove dust and debris from between the keys. Hold the can upright and spray in short bursts.
• Avoid Spills: Protect the keyboard from liquid spills, which can cause permanent damage.
• Gentle Use: Avoid excessive force when typing to prevent premature wear on the keys.

Troubleshooting

If you encounter issues with your keyboard, consider the following common troubleshooting steps:

• Keyboard Not Responding:
  • Ensure the keyboard ribbon cable is securely connected to the motherboard.
  • Restart your laptop.
  • Check device drivers in your operating system. Reinstall or update if necessary.
• Certain Keys Not Working:
  • Check for physical obstructions or debris under the non-functional keys.
  • If multiple keys in a specific area are not working, it might indicate a cable connection issue or a defect in the keyboard itself.
• Backlight Not Working:
  • Ensure the backlight function is enabled via the appropriate Fn key combination.
  • Check your laptop's BIOS/UEFI settings for keyboard backlight options.
• Incorrect Characters Typed:
  • Verify that the correct keyboard layout (Swiss SW) is selected in your operating system settings.

If issues persist after attempting these steps, professional diagnosis and repair may be required.
