What does uncaging refer to in gyroscopic instruments?

Explanation:
Uncaging means releasing the lock on the gyroscope’s gimbals. The gyro inside instruments like the attitude indicator is mounted in a cage with a lock to keep the gimbals from moving during handling, installation, or maintenance. When you uncage it, you free those gimbals so the gyro can float and respond to the aircraft’s actual motions, allowing the instrument to accurately show pitch and bank. This is different from remounting, calibrating in flight, or powering the instrument.
