Step 3: Removing the Line Card Retaining Bar
a) Locate the Line Card Retaining Bar, which is the black
bar spanning the top of the twelve card slots. As shown
in Figure 1-4, the bar is held in position by a
screw/lockwasher/nut combination located on each side
of the CP-220A.
b) Removing the bar is optional. Doing so permits easy
access to the CP-220A's Line Cards (occupying Slots 1
through 8) and circuit cards (occupying Slots 10
through 12), should such cards ever need to be added or
replaced. Note that if the bar is to be removed, it must
be replaced if the unit is ever shipped, to avoid possible
damage to the cards in the CP-220A.
c) Carefully loosen and remove each screw/lockwasher/nut
combination supporting the Line Card Retaining Bar.
As before, to avoid loss, re-thread each set of fasteners
into the hole in the CP-220A's chassis from which they
were removed.
d) Keep the Line Card Retaining Bar in a safe place for
future use.
Step 4: Removing Cards in the CP-220A
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any Line Card or Circuit Card can be withdrawn from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.
Step 5: Obtaining Your Access Code
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.

Remember!
While working inside the
CP-220A,
all sources of
power
(both AC and
Battery Backup) must be
disconnected
. Do NOT
remove any Line Cards or
Circuit Cards when power
is applied.
The Retaining Bar:
An Important Note!
Newer versions of the
CP-220A use a
retaining bar that is
integrated into the
receiver’s front panel,
rather than into its
chassis. If your CP-
220A has this type of
arrangement, it is NOT
necessary to perform
the instructions in Step
3, at the right.
