SYSTEM MAINTENANCE
Read Pages 17 and 18 of the Customer Installation Instructions. You will have a hands-on
exercise to try these tests when you attend class.
CAUTION: Initiating system self-test interrupts call-processing.
Control unit self-tests are made at connector location 10 from the ADMIN mode.
Software changes/corrections cannot be made in the field: all software-related problems
are cleared by hardware replacement.
The programmable memory in the SPIRIT system is NOT replaceable. Therefore, replacement
of the control unit requires readministration of the system. A copy of the customer SYSTEM
PLANNER form (from the Administration Manual) MUST be retained at the control unit.
