System 900 Addressing

The System 900 address consists of two hexadecimal digits that are selected by the eight
sections of the address switch, SW2. Sections 5-8 of the switch select the first (most
significant) digit and section 1-4 select the second (least significant) digit. The address
must not be the same as any other System 900 unit address (see document System
Installation, On-site Paging System, TD 90227GB for more information).
