I bought the PRO T701 thermostat. Out of the box how do I remove the cover from the base so I can attach the base to the wall?

To remove the cover from the base of the Pro1 IAQ T721 thermostat for wall attachment, gently pull the thermostat straight out from the subbase. This separates the cover from the base for mounting and wiring.
