General Description

This new generation barking dog alarm features realistic sounds and voice operating
status. Ferocious barking dogs, greetings or alarms are available. Rex Plus® II is
versatile and provides an excellent way to deter burglars, without the annoying
problems of owning a real dog. With his electronic radar eyes, Rex Plus® II can
“see” through thick doors, walls and glass. Once the cord is plugged into any
standard 120VAC outlet (for indoor use only), he’ll stay
on duty around the clock. Portable operation is available
by installing the optional batteries. For outdoor use,
battery operation only. Note: Rex Plus® II uses a 2.4GHz
microwave radar detection system. It shares operation in
a band of frequencies along with other electronic devices
such as microwave ovens, Wi-Fi, wireless keyboards and
other wireless controls. These can also cause undesirable

false detections. Reducing the sensitivity and repositioning the unit to aim away from
these sources can be helpful.
