WISCO International (Zetron - MODEL 640 DAPT XTRA)

The Model 640 DAPT XTRA is a dial-access paging terminal designed to provide advanced features for systems with moderate capacity requirements. The DAPT XTRA offers exceptional value by providing a powerful system in a compact package at an attractive price.
What makes the DAPT XTRA so powerful is a wide range of standard features - features that are costly options with other paging terminals.

With the DAPT XTRA�s power comes flexibility. The rich feature set means that the basic unit is suitable for almost any application. Specific configurations, such as telephone interface signaling and transmitter control parameters, are easily set in the field. Other functions automatically adapt to the requirements of the moment. For example, the telephone interface can handle voice, numeric, or alphanumeric message entry based upon which pager the user calls. Another example of this adaptability is access for system management: it can be connected either by modem through any dial-up line used for paging or by direct serial connection, depending on the method the system operator uses at the time.
