Background information on sound
Augmented ringing
The ringing volume can be altered using the buttons
on top of the Lifeline 4000 (see the main Lifeline
4000 user guide). The volume can be set as high as
volume 5 (see table). However, there are two further
volume settings, volumes 6 and 7, that cannot be
reached using these buttons. These higher volumes
are used during augmented ringing. Augmented
ringing is where the volume of the ringing gets louder
the longer a telephone call goes unanswered. In
short, volumes 6 and 7 are used only when a
telephone call is unanswered.
Speech volume
The volume of speech can be altered during a call using the volume buttons
on the top of the Lifeline 4000 (see the main Lifeline 4000 user guide).
Once again, the volume can be set as high as volume 5. The user cannot set
the Lifeline 4000 to use volumes 6 and 7. These volumes are only used if a
call operator at a PNC3 control centre selects
Increase Volume
from their
Call
menu during a call.
