A 20 MOA scope base may be if assistance. The built in 20 MOA of elevation will allow you additional adjustment.

I use a strap wrench for such tasks.

If you can move it, you should be able to unscrew it. If you can't us a strap wrench. It has worked for me in the past.

your crosshair actually needs to go lower to raise the point of impact. if thats what you meant than you have a mounting/scope problem. the scope should naturally align within the adjustment range assuming the mounts are correct and the scope is functioning and mounted properly.

I ASSUME this device has collimation screws on the side of the barrel-- if it does not then the prism cannot be aligned.

If it does have collimation screws then hold the small monocular up to a lighted window and adjust the screws until you get a ROUND circle of light-- if you see a "catseye" light circle the prism is not collimated.

You posted this in the Telescope forum.

You will not find a manual for this small telescope and replacement parts are not available.

Sorry

Telescopes that are advertised as having powers of 300, 500, 600 or whatever are scams. You will not be able to see anything but dim blurs if you attempt to use them at such magnifications.

There is a good website for telescope beginners that explains the issues clearly at THIS LINK

Here is their mai9n web site page-- contact them:

You mean a BRAND new telescope and no manual-- or did you buy it used?

Sorry but no manuals for that small telescope on the internet. However Meade maintains a website with all of their telescopes lokkunder th refractor or reflector HEADER for one similar to your telescope.
