Apple PowerBook (Duo 270C) - Manual (Page 241)

Using security features
The Duo Dock has a key-operated mechanical lock to prevent
theft of a docked PowerBook Duo. You can also lock computers
out of the dock—for example, to protect information on the
dock’s hard disk or to limit access to a network.
You can lock the dock when the computer is inside or outside the
dock.
You can lock the computer inside the dock when the computer is
on or off.
To lock or unlock the dock, turn the key as shown in the
illustration.
Each Duo Dock comes with two keys. If you lose both of them,
you can:
n
Contact the lock vendor for a replacement set of keys. Write to
Fort Lock Corporation, 3000 N. River Road, River Grove, IL
60171, USA, or call 708-456-1100 (in Illinois). Be prepared to
supply the code number printed on the tag that came with
the keys.
n
Have a locksmith make a replacement set of keys.
n
Have your authorized Apple service provider replace the
entire lock assembly. The new assembly comes with two new
keys.
All these procedures may be expensive and time-consuming. It’s a
good idea to take precautions not to lose the keys.
The Duo Dock also has a security slot in the back panel to which
you can connect an optional locking cable, to prevent theft of the
dock. See your authorized Apple dealer or representative for
more information.
