Continuous Calling Tone
When there is an incoming call to the specified station,
a calling tone is sounded continuously at the called station.
The continuous calling tone stops if the called party presses
(except key)
1. Use this function when it is difficult to hear a brief
single tone due to high background noise. Any station
can be so made as to be called by the continuous calling
tone, but No.200 programming is required for such a
station (refer to Installation Handbook for EXES-6000
CP-66).
2. If the calling party presses the key while the
continuous calling tone is being sounded, the continuous
calling tone stops to allow the caller's voice call to go
through. Releasing the key restores the conti-
nuous calling tone.
3. If either party continuously presses the key
during the normal two-way conversion, this makes a
one-way conversation from the party who pressed the
key. Releasing the key reverses the one-
way conversation flow and the other party has a domin-
ance (Press-to-Talk).
Notes.
1. In the NP type system that has no Privacy function,
the station can be called by the continuous calling
tone if its Privacy switch is set to ON. This function
by No.200 programming is, therefore, used in the PV
type system having the Privacy function or for the
HF-670M industrial type station equipped with no
Privacy switch.
2. The following stations can be called by the continu-
ous calling tone:
(1) Stations in the "NP" type system or specified
substations in the "PV" type system.
(2) Stations registered for continuous calling tone by
No.200 programming.
