Place a wide angle, that is longer focal length lens in the scope in daylight and focus it and centre on some distant object, a tree, blg, tower etc.
Then use the adjustment screws on the finder to centre it on this same object.
Change to your next higher power lens, that is shorter focal length, refocus and centre, and repeat with the finder adjustment.
Next wait for evening and a bright star or planet to appear and centre it in the finder first this time. It should be somewhere near centre in the lens also. Centre it properly in the lens and make a final adjustment on the finder. .
There our manuals all over the place. Have you check your Library, and have you check the internet . I have seen several places that have that book , check E-Bay also they offer some good scoop books. Your going to have to dig a little for it . If I can remember the places that carry them I will send you a message.
They are used to indicate elevation needed to hit your target at various ranges. The distances should be indicated in your owner's manual. For instance, if calibrated for .223 remington, and sighted in at 100 yards, the first might be 200 yards, the 2nd 300 yards, etc.
During the day: 1. Point to a far (1000 meters or more) object 2. Insert the lowest power (highest number) eyepiece e.g. 25mm 3. focus on the object. 4. Align finder to match what you see in the scope. At night. 1. Put scope out and let it reach the temperature of the outside. 2. Point finder to the moon (1st object you should always use to check scope and finder alignment) 3. Use the same low power eyepiece. 4. If everything seems fine, switch to a higher power eyepiece and enjoy the view. You may have to slightly adjust the finder to align with the main scope. If the views are blurry, the telescope may be out of collimation. Look on the internet for generic collimation instructions. If this still did not help. Throw the scope out! Its probably a piece of junk and will only discourage you.
Unfortunately I can not get the manual for this. I do not think you need collimation at this time. You need to adjust the finder on the scope. Use the highest number eyepiece (lowest power) and point the scope towards a landmark during the day. Now look through the finder. Loosen the screws of the finder and move it until the finder LED is pointing towards the landmark. Tighten the screws. Note: This telescope is more of a toy than a good telescope. Avoid scope that advertise max power in their name. This scope is unable to make 575x! Max power is 50x per inch of aperture on a very good night. 76mm=3in x 50 =150x max!
You will have to shim the scope, use a piece of 35 mm film, It works good, 2 if you need it, if you at extreme measures, you will have to shim the base. You can look through the barrel of a bolt action rifle and see what you will hit at 100 yards, just prop up the rifle in a box or a vise, site down the bore at a target, mailbox, streetlight, then bring the scope to that point, check your barrel again. This will put you on paper at 100 yards. Hope this helps.
You have to sight it in and then insert the ring for the specific ammunition and distance you are using. From then point on, you can dial in the distance and the cross hairs will be right on. It isn't an actual range finder, it's a bullet drop compensator.
