How to test tivo roamio and mini while ensuring the recipient doesn't know?

These two tivo's are christmas gifts for my sister in the family. Neither one has tivo service (She'll set it up) Nor an account (She'll also set it up).

But is there any possible way of unpacking them, plugging them in, checking that they work as they should, and then having it show the factory tivo movie clip and setup process again? This question applies to both the roamio and mini.



Thanks,
