The Key Lock/Drive Power Switch performs three functions. The key lock
assures proper seating of the device carrier within the receiving frame, it turns
power to the device carrier on and off, and it prevents unauthorized removal or
installation of the carrier. For the computer to access data on the Data Express
disk drive, the key must be turned counterclockwise to the locked position.
The key can optionally be attached to the locking mechanism as shown in
Appendix A.

Indicators A and B will alternately blink during the 10 second drive spin up/down period after the key has been turned
on or off. When the carrier has been unlocked from the receiving frame, these lights will flash as the drive spins
down. DO NOT REMOVE THE CARRIER FROM THE RECEIVING FRAME DURING THIS PERIOD to prevent
possible drive damage.
