27. BASIC INSPECTION 

It is recommended to carry out a technical inspection before each 

use. Please check the following: 

•  The rifle scope appearance: there should be no cracks in the 

body, or visible damage.

•  The condition of the objective lens and eyepiece: there should 

be no cracks, greasy spots, dirt or other deposits on the lens.

•  The internal rechargeable battery pack should be fully charged.
•  The control buttons and turret should be in working order.
•  The mount should be tight and correctly installed on the rail.

28. BASIC MAINTENANCE

Always replace the objective lens cap 

(15)

 after use to avoid 

damaging or scratching the lens. Never touch the lens directly; oil 

from your skin can damage the lens coating and surface.

Basic maintenance should be carried out at least twice a year and 

includes the following steps:

•  Wipe the surface of external metal and plastic components 

with a clean, dry cotton cloth. Do not use chemical, corrosive, 

or abrasive cleaners. Canned air may also be used to clean the 

external components.

•  Clean the electric contacts and battery slots on the rifle scope 

using a non-greasy organic solvent.

•  Check the lens and eyepiece. If necessary, remove any dirt 

and sand from the optics; a non-contact cleaning method is 

preferred. 

•  Cleaning the exterior of the lens should only be done with the 

included microfiber lens cloth or similar product. Only clean the 

lens when it is visibly soiled. Frequent wiping or cleaning can 

degrade the anti-reflective lens coating. 

29. WARRANTY

At iRayUSA we’re first and foremost hunters and users of our 

products and we understand that failure isn’t an option. We also 

understand that having to wait extended periods for repair isn’t 

something that a customer should have to put up with when 

something does go wrong. During your published warranty period, 

iRayUSA will repair or replace, at its discretion, any optic that 

becomes defective during normal use. Additionally, if we cannot fix 

your optic in less than one week, we will offer to replace it with a 

replacement product in like or better condition. If you would rather 

wait for your specific optic to be repaired, we can handle that too.

We know you’ve never seen this from a thermal manufacturer, neither 

have we, and that’s why we started iRayUSA.

Our warranty follows the product, and is not tied to the original 

owner. The warranty period is tied to the date of sale to the dealer.

or a condition caused by use other than intended. Any product that is 

modified, opened, or tampered with will void any warranty coverage. 

Any serial number damage or alteration on the product will be
