• When using in bright conditions (early morning or late evening), do not leave the device on with the objective lens cap open for more than 30 minutes. Continuous observation of bright stationary objects can cause the electronic-optical converter to fade, leading to the appearance of dark spots in the field of vision.
• Do not forget to turn off the scope after each use!
• Store with the lens cap on, in the accompanying carrying case.
• The scope has been reinforced with an IPX6 rating against water intrusion and can be used in inclement weather; however, it is not intended for full submersion.
• Attempting to disassemble or repair the scope will void the warranty!
• Clean the scope's optical surfaces only if necessary, and use caution. First, remove (by blowing or carefully wiping off) any dust or sand particles. Then proceed to clean by using a soft cotton tissue and alcohol or a cleaning solution approved for use with multicoated lenses. Do not pour the solution directly onto the lens!
• The scope can be used in operating temperatures, ranging from -30°C to +40°C. However, if it has been brought indoors from cold temperatures, do not turn it on for 3 to 4 hours.
• If the riflescope is unable to mount onto the rifle securely, or if there are doubts about the mounting system, see a qualified gunsmith. Using the weapon with a poorly mounted scope can lead to inaccurate target shooting!
• To ensure reliable performance, it is recommended to carry out regular technical inspections of the unit.

BATTERY INSTALLATION

• Unscrew the cap (1) of the battery compartment counter-clockwise
• Install one AA (1.5V) or CR 123 (3V) battery, so that the (+) and (-) match the markings on the body of the unit
• Tighten the cap (1)

OPERATING THE PHANTOM

• Install the batteries according to the directions in the section entitled “BATTERY INSTALLATION”
• Enter a dark environment
• Remove the objective lens cap by sliding it up on top of the objective lens (2)
• Turn on the unit by turning the selector switch (3) to the “ON” position; you will see the screen of the electronic-optical converter light up green
• The scope can also be checked in an illuminated area, but this is meant solely for testing the device; the lens cap (2) must tightly cover the objective lens
• To adjust the brightness of the red reticle, turn knob (4)
• To select one of the five (three - if EPM66G tube employed) types of red reticles, press button (5)
• Choose a removed stationary object to observe, at a distance of about 100 m
• Turn the focusing knob (6) to “100”, it will settle into a notch
• Observe the object through the scope and turn the diopter focus knob (7) until the image appears crisp
• ·        If necessary, turn on the IR illuminator by turning the selector switch (3) to “IR” position 

• Turn the knob of the IR illuminator (8) until you get a focused IR spot
• After making these adjustments, no further tuning of the diopter is required, regardless of distance or other factors; perfect the image quality using only the knob for the objective lens (6) and that for the IR illuminator (8)
• When finished, turn off the riflescope by turning the selector switch (3) to the “OFF” position and replace the objective lens cap (2) 
• It is possible to mount the scope onto the firearm using a special bracket (9); after the initial mounting is performed, it is important to follow further mounting instructions in the section entitled “SIGHTING IN THE PHANTOM”
• The riflescope can be turned on instantaneously with either the remote control housed in its bracket (10) or by button (11)

SIGHTING IN THE PHANTOM

Sighting in of the scope should be done at operating temperatures, by following the order of these steps:

• Mount the rifle with the scope installed on a scoped machine
• Make sure that no sources of light are visible through the scope's field of vision
• Set a target at a distance of about 100m; the light levels around the target should not exceed 1 lux
• Remove the objective lens cap (2), by sliding it up on top of the objective lens
• Turn on the scope by turning the selector switch (3) to the “ON” position
• Aim the firearm at the target using the mechanical sight
• Adjust the scope according to the steps in the section entitled “OPERATING THE PHANTOM”
• Turn the objective lens focusing knob (6) until you get a crisp image of the target
• Set the desired reticle brightness level by turning knob (4)
• If the center of the reticle crosshairs and the target center do not line up, remove the covers protecting the windage/elevation adjustment knobs
• Using live ammunition, take 3 or 4 control shots, continually aiming at the same hit point on the target (you may also use a laser bore sighter and align the laser point to the center of the cross hairs)
• Examine the target and determine if the aiming point coincides with point of impact, if you determine it's necessary to make corrections, you will need to adjust your aiming point. To move it downwards and to the left, turn the knob (13) counterclockwise, in the directions Down and Left respectively, the aiming point moves upwards and to the right; keep in mind that one click of the knob corresponds to a 20mm shift of the hit point at a distance of 100m
• Check the accuracy of your adjustments by firing another 3 or 4 control shots
• The scope should now be zeroed-in for the specified distance

TECHNICAL INSPECTION

It is recommended to inspect the riflescope before every use. Make sure to check for the following:

• Visually inspect the unit is free from any physical damage; cracks, dents or signs of corrosion disqualify it from proper use
• Check the sturdiness and proper fit of the mounting system
• Ensure the condition of the objective lens, eyepiece and the IR illuminator are free of cracks, grease spots, dirt, water stains and other residue before use
• Visually inspect the condition of the battery and the battery compartment; the battery should be free of electrolyte and oxidation residue, especially where the battery makes contact with metal
• Verify the proper function of the following; selector switch (3), reticle brightness knob (4), reticle selector button and the instant power-on button (11)
• Verify the smoothness of the objective lens focusing mechanism (6), diopter focusing knob (7) and the IR illuminator knob (8)

TECHNICAL MAINTENANCE

Technical maintenance should be done no less than twice a year, and is comprised in the following steps:

• Clean the outside metallic and plastic surfaces from dust, dirt and moisture; wipe the scope with a soft cotton tissue, lightly coating it with gun oil or petroleum jelly
• Clean the battery compartment's electric contact points using an oil-free solvent
• Inspect the eyepiece lens, the objective lens and the IR illuminator and gently blow off any dust and sand, and clean using lens cleaner and a soft cloth; see section entitled “GUIDELINES FOR OPERATION” 

USING THE NVRS 2.5X50 ATTACHMENT

The NVRS 2.5x50 attachment (#29091) increases the magnification power of the 50mm PHANTOM 1.7 times. The attachment screws into the internal groove of the riflescope's objective lens; refer to the instruction manual for the NVRS 2.5x50 when installing. A possible shift of the aiming point may occur and, in that case, it is important to sight in the scope as previously described.

USING THE ADDITIONAL WEAVER RAIL

The scope has a built-in additional weaver rail mount (14) housed on the left portion of the body. This will allow the mount of additional devices, such as:

• The Yukon IR illuminator, with mount (#29072)
• The Yukon NVRS directional microphone with adapter (#27022)
• The Yukon laser sighting device (#27012)

STORAGE

Always store the unit in its carrying case in a dry, well-ventilated space. Store at temperatures above +10°С and at humidity levels no higher than 70%. For prolonged storage, remove the batteries.
