You will not find a manual for this small telescope. The manual only shows how to assemble the scope. It DOES NOT tell you how to use the telescope to find objects in the sky.

Buy this book from or a bookstore:
"Turn Left at Orion"

Also locate a local astronomy club and attend their star parties and meetings.

Meade brand maintains a list of manuals for their telescopes. Look under the REFRACTOR or 4.5 inch REFLECTOR heading for one similar to your scope. They all assemble in the same way.

I have a celestron Cosmos 90 GT Wifi telescope and so far haven't been able to use it. I struggle with aligning the telescope to 3 bright stars... if by chance it says its aligned when I choose a star

Aligning a scope requires several things to be correct.
1. You must follow the setup in manual 100%
2. You must pick the correct alignment stars. Most failed alignments are because you aligned on the wrong star. So alignment requires you to learn the names of a few bright stars and be able to spot them in the sky.
3. With many goto scopes there might be a "home position" to start the alignment. For example, tube pointed roughly North, and level. Check your manual for a "home position. Also time, date, and site must be correct.

Clear skies,

How do you use it [ operating instructions ] ?

I have never heard of this brand??? Is it a reflector style telescope like the picture?

If it is the first thing you should do is take it out side during the day time and practice focusing on a distant object. Use the eyepiece with the largest number written on it. DO NOT USE the 2x barlow if you have one. Also line up the finder scope with the main telescope tube using the top of a telephone pole a good distance away.

Center the top of the pole in the main eyepiece, then with out moving the scope line up the crosshairs in the small finder scope on the same object.

Here is a manual for a similar reflector style telescope made by Meade:

Instruction manual for the astrolon telescope 525

You are about the 10th person to ask for this. These are being sold at Toys R Us and the "toy" really applies to this scope. If you can return it and buy this telescope for your child.

and no you cannot buy a usable scope for less than $200. No manual exists for your telescope, however Meade maintains a web site of manuals for all their telescopes. Look under the REFRACTOR heading on the below web site for one similar to your telescope. They all assemble about the same way, and Meade includes a section in the back of all manuals on how to use the telescope.

This one is similar to your telescope.
