The LDN-ERS36M Night Module features an Image Intensifier Tube of 
Generation-2+, which has enough light sensitivity to function outdoors 
without the help of the Infrared Illuminator.  It may however be 
beneficiary to purchase an extended range IR illuminator for long distance 
shooting or small game hunting.  Infrared Illuminator will provide an 
additional beam of light invisible to the naked eye and is especially useful 
in very dark conditions allowing you to better identify the target and also 
see what is behind the target.  Mounting the optional IR illuminator is easy 
and takes only seconds, as the scope has a special accessory mount 
already built-in the Night Module. 
 
Model LN-EIR-2 extended range LED IR illuminator can be purchased by 
contacting your dealer, or e-mailing us at: 

[email protected]

 (please 

indicate the model number of the unit (LDN-ERS36M)).  You may also see

When using the infrared illuminator it is important to remember that like a 
regular flashlight, as the distance increases, the intensity of the infrared 
light fades away. 
 

DAYLIGHT MODE:   
 

To attach the Daylight 
Module you will first 
need to remove the 
Night Vision Module 
from the Base.  To do 
that you must loosen 
the Night Module 
Mounting Key (2) by 
rotating it 
counterclockwise. 
When the key is 
completely loose (after 
1-2 full circles) grasp 
the base with one hand and the Night Vision Module with the other hand 
and twist the Night Vision Module clockwise until you see the two white 
dots (one on the Base and the other on the Night Vision Module align 
together. Now pull the Night Vision Module out of the Base. 
 
Take the Daylight Module and connect it to the base so that two white dots 
align together.  Now twist the Daylight Module counterclockwise so the red 
dot on the Module is aligned with the white dot on the Base.  Now turn the 
Daylight Module Mounting Key (10) clockwise until it’s tight.  The Daylight 
Module is now attached and the unit should look as image above.
