Instructions for inserting a basic Roamio cablecard?

I've looked for detailed instructions on inserting a cablecard into a basic Roamio and come up empty. Is it really as simple as

1. Turn basic Roamio upside down and open cablecard trap door
2. Insert cablecard with label side up into cablecard slot
3. Close cablecard trap door and turn basic Roamio right side up
4. Done! cablecard operating position is upside down in the basic Roamio

Is this correct? Thanks in advance!
