• At this point, check that your CP-220A's display appears like this:
SYSTEM RESET VER 3.91 01/01/00 00:00:25
• If the Receiver was previously in operation, its
Date
and
Time
and any
data or conditions that may have been reported earlier will be cleared.
However, as already stated, configuration data stored as programmed
parameters will remain intact.
• VER. 3.91 refers to the latest version of the software being used by the
CP-220A as of this writing. The software routines responsible for its
operation have been electronically encoded into an integrated circuit (or
"chip") mounted within the Receiver. Because such software is continually
being improved upon and updated, each time the system is powered on or
reset, the software's version (i.e., revision) number will always appear for
reference purposes.
• The right side of the display indicates the Date, and the Time in a 24-hour
military format (HH:MM:SS). Whenever the CP-220A is reset through the
power-on process, the Date will revert to 01/01/00 and the Time to
00:00:00. The time shown in the figure above reflects the approximate
number of seconds that have elapsed since the Receiver has been powered
on before its Version Number appears.
"Error" Messages
When the NEXT LED is lit at this time, it indicates that the CP-220A has at
least one message to report. As stated in
Section 1,
this is an expected
response due to the Receiver's sensing the lack of several external
connections deemed necessary for its operation. Such messages are used to
report this condition, and it will not be possible to enter the Programming
Mode unless each of these "error" messages has been acknowledged. Until
then, the Receiver will produce a short beep every 30 seconds, calling your
attention this condition.
In order to enter the Programming Mode, these "error" messages must be
displayed – which serves to acknowledge them. To do so, with the NEXT
LED lit, perform each of the following steps to clear all "error" messages. In
the process, some "normal" messages will appear. The beeps will continue to
sound periodically until all outstanding messages have been acknowledged.
The messages listed below are typical but may not be identical to that which
will be displayed by your CP-220A at this time:
