How to use

Connect the numeric keypad to an available USB port on your computer or terminal. The device should be recognized automatically by most operating systems; if required, select the keypad as the active input device in your application. Use the touch-sensitive keys for numeric entry as you would with a built-in numeric keypad. To maintain the waterproof and dustproof properties, avoid disassembling the housing and ensure the connector remains dry and free of debris.

Usage recommendations

For routine cleaning, power down the host device if possible and wipe the keypad surface with a soft cloth slightly dampened with a mild detergent solution. Avoid aggressive solvents or abrasive materials. When installing in industrial or retail settings, place the keypad in a position that minimizes exposure to continuous direct spray while preserving user ergonomics.
