If no automatic timer is set, Night Service must beturned on and off manually.• Automatic Night ServiceAutomatic Night Service is turned on or off according to programmed on and off times.These programmed times use the system clock as a reference, so the system clockmust be set correctly.

Stationusers will never receive a busy signal when they dial 0 or the operator group number.The calls will continue ringing in a queue until answered.Operator RecallsTransferred calls that go unanswered will recall to the station that originated the trans-fer. Should the station that originated the transfer not answer the recall, the call will besent to the system operator as a transfer recall.A call left on hold will recall the station that put it on hold. If the hold recall is unan-swered at the station that originated the hold, the call will be sent to the system opera-tor.
