4. Operating Instructions

The MANHATTAN 176354 Numeric Keypad features a standard 19-key layout, providing all essential numeric functions.

• Num Lock Key: The Num Lock key activates or deactivates the numeric function of the keypad. When Num Lock is active, the indicator light (usually green) on the keypad will be illuminated, and the keys will input numbers. When Num Lock is inactive, some keys may function as navigation keys (e.g., Home, End, PgUp, PgDn, arrow keys).
• Standard Numeric Input: Use the number keys (0-9) for numerical input.
• Arithmetic Operators: The keypad includes keys for addition (+), subtraction (-), multiplication (*), and division (/).
• Decimal Point: The Del key functions as a decimal point when Num Lock is active.
• Enter Key: The Enter key functions identically to the main keyboard's Enter key.
• Backspace (BS) Key: The BS key functions as a backspace, deleting the character to the left of the cursor.
• Triple Zero (000) Key: Provides quick input for three zeros.

Note: The functionality of navigation keys (Home, End, PgUp, PgDn, arrow keys) when Num Lock is off may vary slightly depending on the application and operating system.

5. Maintenance

Proper care and maintenance will help extend the life of your numeric keypad.

• Cleaning: Disconnect the keypad from your computer before cleaning. Use a soft, slightly damp, lint-free cloth to wipe the surface. Avoid using harsh chemicals, abrasive cleaners, or solvents. For cleaning between keys, a can of compressed air can be used to remove dust and debris.
• Storage: When not in use, store the keypad in a clean, dry environment away from extreme temperatures and direct sunlight.
• Avoid Spills: Keep liquids away from the keypad to prevent damage to internal components.
