5.3 Basic Troubleshooting
5.3.1 Replacement Procedure
The RDAC application is used as a general guide for basic troubleshooting, and should be used as
the initial step to identifying faults to the SCM.
For procedure to replace the SCM, refer to Section 14.7.2.5 on page 14-11.
5.3.2 Post-Replacement Optimization Procedure
1. Replacement Station Control Modules are shipped with a default data programmed into the
codeplug (Flash EPROM located on board). After replacing a Station Control Module,
download the codeplug data (unique to the particular station) to the replacement module
codeplug. Simply retrieve the file from the archive and follow the instructions in the CPS
online help facility for saving data to the codeplug.
2. Calibrate the reference oscillator (station reference) by performing the procedure in
Section 14.3.3 on page 14-2.
3. Perform the Tx Deviation Gain Adjust alignment procedure located in the Tuner Service menu
online help facility (also noted in Section 13.6 on page 13-14 of this manual).
4. If a MTR3000 Wireline Interface Board is installed, perform all relevant alignments according
to the Tuner Service menu online help facility (also noted in Section 13.5 on page 13-5 of this
manual).
