Initializing New Systems
Before programming a newly installed DBS 824 system, set its programs to
the default values by performing the following procedure.
Important: This procedure must be performed prior to programming
the
DBS 824 for the first time. Failure to initialize the CPC (Central Processing
Card) may cause operational problems.
This initialization procedure can also be used when you want to return all
changed programs to the default values.
1. Power-off the DBS 824 (set power switch to OFF).
2. Slide the CPC's SW1 switch to RAMCLEAR.
