1. MOUNTING YOUR ATHLON PRISM SCOPE

CAUTION: BEFORE MOUNTING A SIGHTING DEVICE BE SURE

THAT THE FIREARM IS NOT LOADED, HAS ACTION OPEN AND

THE MUZZLE POINTING IN A SAFE DIRECTION. SAFE FIREARM

HANDLING PROCEDURES NEED TO BE PRACTICED AT ALL TIMES.

To achieve the best performance from your rie and

your Athlon TSP1 Prism Scope, your scope must be

mounted properly. If you are unfamiliar with proper

procedures to mount a scope, we highly recommend to

have the scope mounted by a qualied gunsmith

Your Athlon Prism Scope comes with a mount that

works with most of standard picatinny rails. Please

note that the center height of the Prism Scope is 1.39

inches from the center of the scope to the surface of

the rail.

A) FOCUSING THE SCOPE

The purpose of the Fast Focus eyepiece is to focus

the reticle in the scope to your eyes. For a fast focus

eyepiece, just simply rotate the fast focus ring at the

end of the eyepiece in either direction to get a perfect

clear reticle while looking through the scope pointing

at a at plane surface. This is important to do prior to

mounting.

B) ADJUST FOR MAXIMUM EYE RELIEF

i. You need to adjust the scope for maximum eye re-

lief before tightening of the scope mount to avoid

injury from recoil.

ii. With the rie in normal shooting position, look

through the scope and slowly move the scope and

mount back towards you. When you nally see the

full eld of view with sharp and clear edges, stop.

iii. Tighten the mount on the base or rail on top of

your rie.

C) BORE SIGHTING

Bore sighting is a preliminary procedure to achieve

proper alignment of the scope with the rie’s bore.

iv. The initial bore sighting of the scope can be at

short range of 50 yards. This is easier than trying

to bore sight at 100 yards and will get you on the

paper at that distance, so to save time and mon-

ey at the shooting range. We highly recommend

using a bore sighter, but make sure to follow the

manufacturer’s instructions.

v. This can also be done by removing the bolt and

sighting through the barrel on a bolt action rie.

Make sure the rie is placed solidly on a bench

and the bolt is removed. You can then sight

through the bore and center the target inside the

barrel. With target centered in the bore, make

windage and elevation adjustments until the ret-

icle crosshair is also centered over the bulls eye.

D) ZEROING THE SCOPE

IF A LASER BORE SIGHTING OR ANY OTHER SIMILAR DEVICE INSIDE

THE BORE WAS USED, IT MUST BE REMOVED BEFORE FIRING. AN

OBSTRUCTED BORE CAN CAUSE SERIOUS DAMAGE TO THE GUN AND

POSSIBLE INJURY TO THE SHOOTER.

i. Ideally set the rie on a two or three holding

point gun rest, and then re three rounds at a

target 100 yards away. Observe the bullet holes

on the target and calculate how far those bullet

holes are off the center of the target, and then

adjust windage and elevation knobs to move the

center of reticle up, down, left or right. Fire an-

other three rounds, then observe and adjust. Re-

peat this step as necessary until the three round

bullet holes are perfectly aligned with the center

of the target.

ii. Setting Windage and Elevation

Athlon Prism Scopes have capped windage and

elevation turrets. Simply remove the cap and use

the knob on the top of the cap as a screwdriver

to adjust the windage and elevation. Put the cap

back on once your rie is sighted in. By zero-

ing the rie at 100 yards, the shooter can calcu-

late how many clicks of adjustment are needed

for different distances or wind conditions. After

shooting, the shooter can quickly reset the prism

scope back to 100 yards by turning the knobs

back to zero.

Athlon TSP1 Prism Scope has 1 MOA for click values

of elevation and windage adjustment. MOA, a unit of

angular measurement, is dened as a minute of angle,

a minute is 1/60th of one degree and 1/21600th of a

circle. One MOA equals 1.047-inch (rounded down to

one inch) at 100 yards, two inches at 200 yards and

to ten inches at 1000 yards. 1 MOA per click takes one

click to move point of impact one inch at 100 yards.

A) ILLUMINATION SETTINGS

The illumination switch is set on the left side of the

scope chassis. Athlon offers variable 1-10 brightness

settings and two colors settings (red and green) for

the reticle. Press UP button to turn the unit ON. Press

and hold the UP button for 3 seconds to turn it OFF.

Use the UP button to make the reticle brighter and

the DOWN button to make it dimmer. The unit auto-

matically turns OFF if no adjustments are made in 6

hours. Press UP and DOWN button at the same time to

switch between reticle colors. The unit automatically

sets the illumination at the last setting after a new

battery is installed.

Battery Chamber Cap

The illumination is powered by a AAA battery. Re-

move the battery chamber cap by turning it count-

er-clockwise and then set the battery with the posi-

tive (+) side facing in. Reinstall the cap by turning it

clockwise, DO NOT OVER TIGHTEN.

3. MAINTAINING YOUR PRISM SCOPE

Disassembling or cleaning the scope internal-

ly will void the warranty. If the scope requires

repairs, please refer to the warranty section for

complete instructions.

The external optical surfaces should occasionally

be wiped clean. Use the lens cloth provided or an

optical quality lens paper to wipe out dust or dirt

on the external lens surface. If large sand parti-

cles or heavy dirt contamination is observed, re-

move using soft brush or by blowing them away.

Apply lens cleaning liquid before wiping off. Al-

ways keep the protective lens covers in place

when the scope is not in use to avoid dust collect-

ing on the surface of the lenses. Store the unit in

a low-humidity environment.

4. TROUBLESHOOTING TIPS - Inaccuracy Issues

Check scope mounting and make sure there is

no movement when pulling the scope by hands.

Tighten the mounts if there is any movement ob-

served.

Use a bench rest or sandbag to support the barrel

and stock when making windage and elevation

adjustments. This will help eliminate movement.

It is recommended using the same type of ammu-

nition with same weight.

Check your rie stock, as a loose stock changes

the point of impact.

Make sure your rie chamber and barrel are clean

Make sure riing of the barrel is not damaged and

no excessive grease inside the barrel
