Upon receiving a call, the screen (18) will show the
image of the visitor, but audio communication with
the visitor will not be initiated unless the call is
answered by a short press of the Talk/answer button
/ (16).
Once the Talk/answer button / (16) is pressed,
conversation is now possible and the voice of the
visitor can be heard from the speaker (19). To talk
back to the visitor, press and hold the Talk/answer
button / (16) and speak towards the microphone (17) once you see
the text "TALK BACK" appear at the lower right corner of the screen (18)
(If you speak before seeing the text, then it is possible that the visitor may
NOT be able to hear some of your first spoken words.).
Release the Talk/answer button / (16) after you finished speaking to
listen to the visitor. It should be worth noted that the voice of the visitor
cannot be heard while pressing the Talk/answer button / (16). Upon
finishing the conversation, short press the Power/hang up button (15)
to end the call.
In case you need to get a more magnified image of the visitor, short touch
the menu key (11), then short touch either the left/right key (9) (10)
to achieve a 2x zoom image on the screen (18).
Besides, to get a wider scope of view at the door entrance, you can use
the image shift function. Short touch the image shift key (12), then use
the left/right key (9) (10) to shift the image on the screen (18).
This system has an automatic end call feature. In case the resident does
not talk back to the visitor (i.e. press the Talk/answer button / (16))
for over 60 sec, the call will be ended automatically. Such a feature is
useful to protect your privacy in case you forget to end the call by
pressing the Power/hang up button (15).
Once a call has been answered, you can use the
door lock open key (13) to remotely open the
electric door latch for the visitor (this function is only
available if there is 12V DC supply to the caller unit
and your door is equipped with an electric latch).
Long touch the door lock open key (13) for over 3
sec and the text "DOOR OPENED" appears on the
screen (18', showing the door latch is opened. The
text will disappear after 3 sec.)
Under standby mode (i.e. when no call is set up between handset and
caller unit), the electric door latch can also be opened by a short press of
the Talk/answer button / (16), and then a long touch of the door lock
open key (13) for over 3 sec.
