Once the Line Card Retaining Bar has been removed,
any Line Card or Circuit Card can be withdrawn from
the CP-220A by firmly grasping its white handle, or
card puller, and pulling straight out. Once it has been
removed, handle the card carefully.
To properly set up your CP-220A, it will have to be
configured, or programmed, for the operation desired. To
"enter" the programming mode, you will need an Access
Code, unique to your CP-220A. Information on obtaining
this Access Code can be found on the first page of this
manual – a page that should be removed for security
reasons. If you haven't already done so, locate this page
and use the information provided to obtain your Access
Code.
At this point, store the page apart from the manual for
safekeeping. You will have to use the Access Code in
Section 2 when you first "enter" the programming mode.
