2. SERVICE CALL CONDITION
When a service call condition occurs, the Call Service indicator and service
call codes are displayed.
When the service call conditions E2, E3, E4, E5, E6, E7, and E8 conditions occur,
for safety reason they cannot be cleared by turning the main switch off and on.
Accessing SP38 and changing the date from "1" to "0" must be done to clear
these service call conditions.
