That's because it's not a button. It's the ring around the shutter release button. There's a little grip at the front of the ring. Push it one way to zoom out, the other way to zoom in. See the illustration on page 13 of the manual.

Sorry no owners manual for that scope. However Bushnell has all of their manuals on this web site-- find a scope similar to your scope-- they all assemble and are used in a similar fashion.

The digital zoom works fine on mine. It sounds like your have encountered a couple of defective models.

However, even once you get the digital zoom to work, it gets really grainy, so I don't use it.
