Pairing The Handset(S) To The Door Unit - Marmitek DOORPHONE 120 Guide Utilisateur

4. Place the supplied battery pack into the battery compartment. Be careful about using the
right polarity of the batteries and the handset (22) and place the battery cover back onto
the handset.
In case you are using the handset(s) in combination with a 4-doorbells door unit, then you can
set the handsets on channel 1, 2, 3 and 4 respectively. They should correspond with the door
unit switches 1, 2, 3 and 4.

4. Pairing the handset(s) to the door unit:

The pairing procedure is essential for the set to function. Every door phone system is provided
with a unique identity code (ID), so that only the handset and the door unit can communicate
with each other. There are more than 65.000 different code combinations, so that the chance
that someone else in your area has the same code is extremely small.
Beware! It is necessary for the pairing procedure that the alkaline batteries in the door unit be
fully loaded. In case the external power supply has already been connected to the door unit,
then disconnect the power supply for the pairing procedure.
