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.
