How do I properly maintain and clean the Airam 7126612?

The alarm must be kept clean and maintained once a month. Use a vacuum cleaner to remove visible dust, then wipe the surface with a slightly damp soft cloth — do not let the cloth drip. Check for battery leakage and replace batteries if leakage is found, and never clean the alarm with chemicals such as alcohol, gasoline, or cleaning agents as these can cause damage. After cleaning, always test the alarm with the TEST button before reinstalling.
