Chapter 4 - Telephones and Optional EquipmentChapter 4 4 - 434.14.4 APR AdaptersThe APR Adapter provides an analog interface for the digital Value keyset. It provides ringing which allows theconnected device to be used for incoming and outgoing calls. This adapter also provides a separate extensionnumber for the analog device, which allows both devices to be used at the same time (this can be removed insystem programming if you wish).The adapter receives it power from the keyset. The maximum distance between the APR Adapter and theanalog terminal is 49’.When installing or removing the adapters, the keyset should first be unplugged from the system.Telephones with an adapter installed can be wall-mountedThe APR Adapter does not support reverse-polarity.For specifications, refer to Section 6-1 UX5000 SYSTEM SPECIFICATIONS in Chapter 6 - Specifications andParts List on page 6-1.4.14.4.1 Installing the APR Adapter:1.
