If it was supplied with batteries ensure any insulation is removed and they are in good condition and fitted the right way around. Check in the manual you have done everything as per instructions and if it still doesn't work, send it back to the supplier for refund or exchange.
When something is supplied with batteries there is usually a plastic insulating strip to prevent a contact being made.

Not at all - the screws are likely to have a standard thread and shouldn't be difficult to identify which and the eyepiece is a sort of optional extra.

Telescopes are generally supplied with an eyepiece but after a while an enthusiast could decide to buy an upgrade. Below is a link to a suitable website...

It's just half a binocular, or a hand held telescope that uses prisms to reduce the physical size.

A monocular is a modified refracting telescope used to magnify the images of distant objects by passing light through a series of lenses and usually prisms, the application of prisms resulting in a lightweight, compact telescope.

When I bought the Vivitar 10 X 25, I thought there was no CD in the box...... but it is essentially hidden inside the box behind the piece of loose dark paper.

As someone else has previously suggested; if you need another one, download it here;

Yes, you will need a license to operate as a gunsmith in the United States. However, you won't need a gunsmithing license. As far as I know, no US state requires that gunsmiths have a state-issued license. This means you also won't need to undergo any training or take part in any type of apprenticeship in order to become a gunsmith. You'll become a gunsmith the moment you start claiming to be one.

If you are wondering that type of license gunsmiths need, that'd be a Federal Firearms License (FFL). This type of license is a basic requirement for any business that plans on working with firearms within the United States. To get one, you'll need to fulfill some basic requirements, including going through an interview and an inspection of your future workplace. It's generally not hard to get an FFL.

But again, since this is a general license and not something made for gunsmiths, you won't have to prove yourself a competent gunsmith to get one. You'll just have to show that you understand the basics of gun safety and meet their requirements.

If you'd like to become a gunsmith, this guide can help you get started.
