5. Operating Instructions
The Fujitsu KB521 is a standard QWERTY keyboard with a combined Russian/US layout, offering familiar functionality for typing and system control.
- Standard Typing: Use the alphanumeric keys for text input.

- Numeric Keypad: The dedicated numeric keypad on the right provides quick entry for numbers and mathematical operations. Ensure Num Lock is active.
- Navigation Keys: Use the arrow keys, Home, End, Page Up, and Page Down keys for navigating documents and web pages.

6. Maintenance and Care
- Cleaning: Disconnect the keyboard from your computer before cleaning. Use a soft, lint-free cloth, slightly dampened with water or a mild cleaning solution, to wipe the surface. Do not spray cleaners directly onto the keyboard.
- Dust Removal: Use compressed air to remove dust and debris from between the keys.
- Storage: When not in use for extended periods, store the keyboard in a clean, dry place, away from direct sunlight and extreme temperatures.
