Starting Up - RiTTO Twinbus 1 7630 Quick Reference Manual

Starting up

The system can be started using the indoor telephone, indoor video unit or apartment doorbell button. Start-up using
the apartment button is useful if you do not have access to the residential unit.
In order to allow the operator to change the call tone of the main bell button, the main bell button must be programmed
as the main button when initial setting takes place. The procedure must be repeated for other bell buttons.
The intercom can be used for start-up with two persons.
An internal call number must be assigned to each indoor telephone for internal communication. When the internal call
number is programmed, the indoor telephone is known to all subscribers connected to the bus line. For example, sub-
scriber 1 is selected by all other subscribers using the button that has been assigned to subscriber 1 as the internal
call number. Please print the labelling field of all the indoor telephones accordingly.
