OPERATING MANUAL 

 
Please read this manual before using your RANGER.  
RANGER is equipped with a built-in, high power IR-illuminator that has a gradual IR adjustment and 
memory controller, which provides effective viewing in most night conditions. The unit can be 
attached to a standard tripod that uses a 1/4 inch mounting thread. RANGER has a built-in video-out 
connector which can be used to pair the device with a monitor or to record video via a recording 
device (such as a video camera). For the best image quality, it is recommended to set up the unit on a 
tripod before attaching the video cables and recording devices. 
The unit is equipped with a special connector that allows RANGER to be powered by a 12 volt car 
outlet. It operates for up to 10 hours using 6 AA batteries.  The RANGER has an ergonomically-
designed, water resistant, durable plastic body that helps protect the unit and creates versatility.
