Group Paging: Special 2-digit access codes 
(81, 82, 83 or 84) permit voice paging to one 
of four zones. Zone assignment is via soft-

continuously when the system is in night 
service. This mode is intended for indirect 
control of an answering machine. 
2) Night Bell Control: If the strap is cut, 
the relay pulses at a 1 -second on/3-sec- 
onds off rate whenever the system is in 
night transfer mode and an incoming call 
is ringing the system. This mode is in- 
tended to be used for indirect control of 
an external night bell.
