You want to notify them when an admin makes a change to their profile? There are no checkboxes for usergroups within CB so unsure what you're changing exactly. It's possible to do this using CB Auto Actions and its Email action. You could even use a PM action if you wanted. Example setup as follows.
Type: Email
Triggers: onAfterUserUpdate
Access: Everybody
Conditional: [var1_user_id] Not Equal To [cb:userfield field="user_id" user="#me" /]
To:
Subject: Your Profile has Updated
Body: You profile has been changed by an administrator
Note the above is for frontend only changes. If you want backend too then add the onAfterUpdateUser trigger.
