Most of the test results are self -explanatory, however some of the tests may result in a failure code.
Codes 40H 20H and 10H indicate component failures. Power the console down then up, unplug the line cord, re-insert and restore power. If still faulty there is an electrical fault , the console will need to be returned.
Codes 08H ,09H to 0FH refer to key failures in the columns A to F .The test procedure is to power the console down, free the key if stuck and power the console back up. If still faulty power down the console again ,unplug the line cord and reset the power. If the fault still persists the console is faulty and should be returned.
The full details of these tests are contained in NTP 553 2201 117. This is the Planning and Engineering guide Book 1 of 3 - M2250 Attendant Console.

Common Problems-
1. The Meridian Communications Adapter MCA- Installation and configuration details are contained in NTP 553 2731 109 - Meridian Data Services Book NTCK29.
2. Difficulties are encountered when putting the Attendant Console into night service, the display shows BUSY instead of NITE.
This is normally due to an Attendant Overflow DN (AODN) defined in Ovl 15,
not having its Make Set Busy key (MSB) operated.
To save going and placing all the appearances of the AODN into MSB from the Attendant Console you can force the system into N/Service by using ... ... Shift + Night.
All the best
