Continuous Calling Tone
When a specified station receives a call, the calling tone
continues until
is depressed by this party.
1. When calls cannot be answered immediately or when it is
difficult to hear a normal calling tone due to high back-
ground noise, the station should be provided with the
continuous calling tone function. There is no limit to
the number of stations that may be equipped with this
function, but a No.200 registration must be completed.
2. When the caller depresses the bar while the conti-
nuous calling tone sounds, he can talk to the person
called by one-way. When the bar is released, the
continuous calling tone returns.
3. During two-way conversation, each party presses the
bar to talk and releases the key to receive the
other party. (Press to Talk)
Note.
1. In the event of the system without Privacy function
(NP Type system), stations with Privacy switch in the
ON position are called by a continuous calling tone.
By No.200 programming, this continuous calling tone
function may also be made available to the system
having Privacy function (PV Type system) and to
industrial type of station model HF-650M.
2. Two (2) different continuous calling tones may be
employed in
(1) stations used in "NP" type system having a
standard function of "continuous calling tone".
(2) specific stations provided with a "continuous
calling tone" function by station No. 200
programming.
