Digital Clock. The
console digital clock is driven by pulses
derived from the system master clock circuit, and therefore is a
direct indication that the system master clock.'is running and that the
data connection is properly connected. The colon between the hour
and minute display is a positive indication that the console is receiving
power from the system.
4.52 Error Codes.
The error codes (Table 4-4) displayed on the
console indicate the card causing the malfunction and the type
of malfunction. Figure 4-8 shows a typical error display and its inter-
pretation. Figure 4-9 shows the equipment numbers and card posi-
tions. The alarm may be cancelled and removed from the console by
dialing *8# (assuming the use of * as the Supervisor function) and
then pressing the RELEASE button. This will remove the alarm from the
console but will not debusy the affected circuit. To display the remain-
ing errors, the preceding errors must be canceled by the service
person.

will also present this error. In either case the RAM should be initialized
