BATTERY INSTALLATION 

 
Your Patrol-D 3x42 runs on two AAA batteries. To install, unscrew the battery compartment cover, 
insert the batteries into the battery compartment so that the positive (+) and negative (-) terminals 
of the batteries match the markings inside the compartment, replace the battery cover carefully. Do 
not overtighten. 
 

USE AND TESTING 

 
Make sure that the two AAA batteries have been installed according to instructions found in the 
battery installation section of this manual. 

 

Move into a dark area before activating the Patrol-D 3x42 unit.  

 

Remove the lens cap (1) by sliding it on the housing of the device. 

 

Remove the protective cap from the booster lens. Insert the booster lens into the objective 
lens of the device up to the stop and, preventing the objective lens from overtwist, rotate it 
clockwise so that the three protuberances at the bottom of the booster lens engage the 
grooves inside the objective lens.   

 

Activate the device by pushing the "ON" button (3). 

 

If you wish to test your night vision device in a lighted area, be sure the protective cap of the 
booster lens is in place prior to pressing the “ON” button. The lens cap has a pinhole 
opening to admit a small amount of light for testing purposes. 

 

If the subject to be viewed is in a completely dark area, including lowlight shadow areas, 
activate the infrared illuminator by pressing the “IR” Button (2) located next to "ON" 
button.
