The Platea/Tekna Plus/Uno monitor and the T-740 Plus/Uno telephone can be used to receive the
calls made from the apartment door, saving the use of a bell. Wire the push button of the
apartment door to the 'HZ ' and ' ' monitor or telephone terminals.
The reproduced acoustic tones are different depending on their provenance, that allows the user
to distinguish where the call is made from. If during a conversation a call is made from the
apartment door, acoustic tones will be reproduced on the handset to advise that someone is
calling.
