If the fan connected to the system stops working, the system will shut down after 24 hours
to prevent overheating. This function is programmable, providing an alarm to a pre-
programmed extension. The procedure is as follows:
1) Specify the SYSALM key in MMC 722. Program the specified key on the digital
phone to be alerted.
2) If an alarm occurs in the phone, the reason for the alarm is displayed in MMC 851.
Error 'MJA08' indicates a faulty fan and that the system will be turned off after 24
hours.
If this alarm occurs, replace the fan within 24 hours.
