Installation and operation manual for the STI Mugger Stopper® Plus #12006 Personal Protection Alarm.
Installation and operation manual for the STI Mugger Stopper® Plus #12006 Personal Protection Alarm — a compact personal safety alarm with a 120 dB ear-piercing alarm, attention-grabbing strobe light, and built-in flashlight.
The Mugger Stopper Plus is designed for personal protection: it emits an ear-piercing 120 dB alarm combined with a strobe light to attract attention and deter an attacker, and can also be used to summon aid in the event of an injury or fall. It also includes a built-in flashlight, handy for finding keys or a keyhole in the dark.
The Mugger Stopper Plus alarm is extremely loud. Never place the unit close to your ears. To test the alarm, direct the unit away from you at arm's length and pull out the pin on top of the unit.
Three-year warranty, or a one-year limited warranty (from date of purchase) on most products — see the STI website for details. Electronic warranty registration is available at www.sti-usa.com/wc14.
