7. Connect the ribbon supplied ribbon cables
between RCTU BA and BB and RSIU, if installed;
or, RCTU C and D and RSIU, if installed (see
Figure 4-39).
Note:
Do not adjust the C14 or C15 trimmer
capacitor. The capacitor is factory-calibrated.
CAUTION !
When transporting the RCTU PCBs, keep the
P8 or P9 battery jumper in the " O N position in
order to save the configuration data stored in
RCTU RAM. (The battery will protect RAM for
approximately six years.) Otherwise, to
conserve the lithium battery, move the jumper
to the "0FF"position.
When packaging the RCTU PCB, use only a
nonconductive material enclosure, such as
plain cardboard. Conductive material can
cause the internal battery to discharge and
erase memory in the RCTU PCB.

Refer to Chapter 6-Peripheral Installation to connect
a MOH/BGM source to the the RCUTA, RCTUB,
RCTUBA or RCTUC.
Common Control Unit Programming
Overview
After initially installing a new and unused common
control unit, all on-board RAM memory needs to be
erased and initialized by running Program 91-9 twice
after all other PCBs are installed. If RAM contains
configuration or feature data from previous
programming that should be retained, do not run
Program 91-9. See the Programming Part. If installing
a RCTU PCB, Release 3 or above, perform a
processor RAM test using Program 00, part 2. On new
RCTU installations, the RAM test should be run after
RCTU initialization and before entering the customer
database.
The following parameters may be specified, through
programming, for the RCTU PCB.
January 1996
Program 00, part 2-RCTU
Program 03
For RCTUA (1 or 3). Specify Code 91 (no RRCS),
92 (four RRCS circuits), or 93 (eight RRCS
circuits) 94 (12 RRCS circuits) for slot "00"
("RCTU").
For RCTUB (1 or 2): Specify Code 91 (no RRCS),
92 (four RRCS circuits), 93 (eight RRCS circuits),
or 94 (12 RRCS circuits) for slot "00" ("RCTU").
For RCTUBA and RCTUC/D: Specify Code 91 (no
RRCS), 92 (four RRCS circuits), or 93 (eight
RRCS circuits), 94 (12 RRCS circuits). Assign the
appropriate code for each PCB. slot 00 for
RCTUBA or RCTUC (1 or
RCTUD (1, 2 or 3).
Note:
91-2 must be run after Program 03.

Program can be skipped and Program

91-1 or 91-9 can be run instead.
