• What if a doorphone call is not answered?
If not answered within 30 seconds, the call stops ringing and is canceled.
• Unlocking the door opener
During a doorphone call, any extension user can unlock the door opener (user-supplied)
from their extensions by dialing "5" to let the visitor in.
• You cannot hold and transfer the doorphone call.
• The door can be unlocked by the following:
1) Extensions that are programmed to receive doorphone calls.
2) Any extension that is engaged in a doorphone call.
• While talking to a doorphone, you can unlock the door using the One-Touch dialing button
instead of dialing "5." In this case, "5" must be stored in the One-Touch dialing button by
Station, User or System Programming.
• With the KX-T7431, KX-T7433, KX-T7436 or KX-T7235, you can call a doorphone and
open a door using the display operation.
