You can test the siren, LED light, and emergency alerts of your Plegium Smart Pepper Spray (and the emergency alerts of you Plegium Smart Mini Pepper Spray) without triggering the actual pepper spray (which you want to save in case you'd have to use it in an emergency situation).
To test the device, slide down the test switch on the side of the product for 10 seconds, then slide it back up. Remember to inform your emergency contacts that you are testing your product, so they don't mistake the test alerts for real emergency alerts.
