Position the mobile device so that the display is facing you and the charging contacts are facing down (the same way you would position a device before inserting it into a charging SharedCradle).
Tilt the device slightly backward and move it underneath one of the locking clamps while lifting the clamp up. The locking mechanism only engages if a device is present in the SharedCradle.
Align the mobile device with the charging SharedCradle and lower it into position. Once the device has come to rest, a low click sounds, which indicates the lock engaging. The mobile device is now locked in position in the SharedCradle.
