Vortex Optics CROSSFIRE 1.5-4X32 - V-PLEX - Manual (Page 2)

To change the power, turn the magnification ring to the desired level. Use lower powers (which offer a wider field of view) when you may need to
make a quick shot at closer distances.
3. Variable Magnification Adjustments
A fi xed-power rifl escope has no magnifi cation adjustment.
Adjustable Objective
Parallax is a phenomenon that results when the target image does not quite fall on the same optical plane as the reticle within the riflescope.
When the shooter’s eye is not precisely centered in the eyepiece, there can be an apparent movement of the target in relation to the reticle which
can cause a small shift in the point of aim.
4. Parallax Adjustments
Adjustable Objective (AO) Lens
Setting the adjustable objective lens on the AO models is very easy.
1. Be sure that the reticle is properly focused (see page 6).
2. Match the range number on the objective lens barrel(distance you are
shooting) as closely as possible to the indicator arrow on the riflescope body.
For the best accuracy, use a laser rangefinder to measure distances.
3. Check the setting by moving your head up/down and left right while
looking through the scope. The setting is correct if there is no apparent
movement between the reticle and target. If there is movement, continue
adjusting the lens slightly until the movement is eliminated.
Illuminated
Reticle
Knob
Select riflescopes in the Crossfire series
use a variable intensity reticle illumination
knob. Rotate the knob in a clockwise
rotation to increase the illumination
intensity; adjust the dial on the knob to
turn the illumination off and on.
5. Illuminated Reticle Adjustment
Use a coin to remove the outer cover and
replace the battery. The battery operates
on one CR 2032 Lithium battery; typical
life is up to 1,000 hours (Level 1), 70 hours
(Level 6), 25 hours (Level 11).
Battery Operation
Riflescope Installation
To get the best results from your Crossfire riflescope, proper mounting is essential. Although not extremely difficult, the correct steps must be
followed. If you are unsure of your abilities, it would be best to use the services of a qualified gunsmith.
Your Crossfire riflescope is pre-set at the factory with the
reticle centered in both adjustment ranges; this is the ideal
position to begin sight-in. If you have changed the settings and
wish to re-center the reticle, follow this procedure:
1. Centering the Reticle
A. Turn either dial (windage or elevation) as far as you can in
one direction until it stops.
B. Turn the dial in the other direction until it stops, carefully
counting the rotations as you turn the dial.
C. Turn the dial back again to half the number of rotations counted
in Step B—the reticle will be centered for that adjustment only.
D. Repeat for the other adjustment so that the reticle is centered
in both the windage and elevation settings.
Base
Rings
Using high quality, appropriately-sized (1-inch
or 30mm, depending on riflescope model) rings
and bases matched to your rifle, mount the
scope as low as possible on the rifle. Be sure to
follow manufacturer instructions supplied with
the rings and mounting base. Whether you use
high, medium, or low rings will depend on the riflescope model and your
particular firearm. A lower mounting will help assure proper cheek weld,
and aid in a solid shooting position and fast target acquisition.
We recommend using the lowest rings that will give complete clearance of
the riflescope and rifle. Avoid any contact with the barrel, receiver, bolt
handle, or any other part of the rifle. Work the riflescope’s zoom ring and
rifle’s action to assure no contact.
2. Mount As Low as Possible
Parallax causes the greatest problem on small targets at
high magnification as with varmint and target shooting.
Selected models come with
an adjustable objective (AO).
Most other models are set at
the factory to be parallax-free
at 100 yards; Rimfire models
are parallax-free at 50 yards.
