Bushnell 3.5X 用户手册

No focusing or diopter adjustment is necessary on models with no magnification 

("1x"). The clarity and resolution will be as sharp and defined as can be seen 

with your eyes. Models with magnification ("3.5x") provide a diopter adjustment 

ring, located around the outside of the eyepiece to compensate for differences 

in individual eyesight. Looking through the scope, first turn the reticle intensity 

control up until the reticle is easily visible, but not too bright. Then rotate the 

diopter ring until the reticle appears sharp to your eye. You may find it helpful 

to have the scope pointed at a simple, uncluttered background (for example, a 

white wall) as you adjust the diopter, so the reticle can be seen more clearly.

If your scope is mounted improperly, you may never achieve the best accuracy 

from your firearm. You may choose to mount your own scope or opt to have a 

gunsmith do it for you.

Your scope should be mounted as low on the firearm as possible. This will keep 

your face or cheek close to the line of sight and will also keep the scope close to 

the center line of the bore – both factors will help you attain optimum accuracy. 

When properly mounted, the scope will be as near center as possible, allowing 

for a full range of elevation and windage adjustments.

The Bushnell Illuminated MP Scopes feature an integrated mount, ready to 

accomodate standard Weaver or Picatinny type mounting rails. 

Bore sighting is a good preliminary procedure in achieving proper alignment of 

your scope to the firearm. It is best performed with a Bushnell Bore Sighter. If 

not available, it can be done adequately in the following manner: Sight through 

the gun barrel at a 100 yard target. Then sight through your scope and bring the 

reticle to the same point on the target. The reticle is illuminated by turning on the 

on/off switch. Rotate the knob until you have achieved the desired brightness.

Major elevation adjustment should not be needed but, if necessary, it should 

be accomplished by shimming  the mount base. It is important not to use the 

elevation adjustment of the scope for major adjustments.  Your scope’s internal 

elevation adjustment should be reserved for fine tuning to achieve zero at the 

called for distance.

Final zeroing of your firearm and scope should be done with live ammunition 

and based on your expected shooting distance. If you anticipate most of your 

shooting at short range, zero-in at 50 yards. Groups of three shots will be useful 

for averaging the point of impact.
