Basic System Operation
Call sequence
When the
call
button is pressed at the entrance panel it causes the videophone to ring and
the amber
view
lamp to flash. The videophone will continue to ring for up to 30 seconds
or until the resident responds by picking up the handset. At this time the resident can
freely converse with the visitor whose image is now displayed on the videophone; at the
same time the green
lock
lamp will flash to highlight the
lock
button.
The call may be terminated by replacing the handset or more usually by pressing the
lock
button first to allow the visitor access through the entrance; the speech and picture will
persist for a further 3 seconds while the door is being released.
Videophone Controls
The diagram in the introduction shows the standard colour monitor and its controls. The
default setting is ringer volume midway and contrast maximum (slide finger to top).
Auto Display
When ‘Auto Display’ mode is selected the picture will come on while the videophone is
ringing, otherwise the picture will only come on when the call is answered. Auto Display
mode is usually pre-selected at installation and generally only one videophone per flat
should be set in
this mode (see ‘Extension Videophones’ below).
Call Mute
The resident can mute the ringing sound in the videophone when they do not wish to be
disturbed. Call mute is activated by pressing the
mute
button on the videophone, which
then illuminates in red as a reminder. The handset must be on the hook for this to work.
Pressing the
mute
button a second time will disengage the mute function. During
installation it is possible to set a time limit for the mute function in various values from 2
minutes up to 10 hours, indefinitely or disabled. When this time period has elapsed the
mute function will automatically disengage.
(See ‘mute timer’, page 22).
Mute only stops the audible ring, but the amber
view
light will still flash and all other
functions work normally. Mute will continue for the preset time even if a call is answered.
Silent viewing
When the videophone is ringing the resident can press the
view
button to answer the call
instead of lifting up the handset; this will stop the videophone ringing and enable them to
view the visitor for up to 60 seconds or until the
lock
button is pressed to release the door.
Silent viewing can be ‘normalised’ at any time by picking up the handset and conversing
with the visitor as described above.
Door Status Indication
The green
lock
lamp on the videophone will illuminate to warn the resident that a door has
been left open following a call. This feature requires a door monitor contact to be fitted.
Call Privacy
Once a call has been answered by one videophone no other videophones may join in,
view or listen to the call. If another videophones handset is picked up, or the
view
button
is pressed, the videophone will not activate.
