Installation Warning
This equipment generates and uses radio frequency energy. If the Model 640 is not installed and
used in accordance with this manual, it may cause interference to radio communications.
The Model 640 should only be installed by experienced radio and paging systems personnel.
Specialized knowledge in telephone systems is also critical for interfacing the Model 640 with
the telephone network.
CAUTION
Always power down the paging terminal before removing or installing cards. The
Model 640 is not designed for “hot” removal/insertion of cards.
Initial Unpacking and Inspection
The following procedure prepares the technician for the actual installation of the paging terminal.
It includes a general familiarization with the hardware and confirmation of the correct custom
system ordered from Zetron. Some or all of this procedure may have been completed already.
Skip any steps that are superfluous.

Unpack the Model 640 from its box.
q
2.
Remove the six screws that hold the paging terminal top cover in place.
q
3.
Remove the top cover of the Model 640 and set it and the screws aside in a safe
place.
q
4.
Check the unit against the order receipt to ensure that all purchased options were
shipped from the factory.
Refer to Section 3 for details on the location and operation of each card (standard and
optional) in the Model 640 chassis.
q
5.
Make sure all circuit cards, in each and every occupied slot, are firmly seated.
CHOOSING AN INSTALLATION METHOD
There are basically two interface options available for dividing the telco and radio connections.
Each method can be modified in an endless variety of ways for a custom application.
Optional Installation Interface Assembly
This optional kit (Part No. 950-9334) includes a terminal block adapter for telco and radio station
connections. The terminal block adapter plugs directly into the RJ21 connector on the rear of the
Model 640 chassis. It provides two Wiedmueller connectors for the radio station interface and
four RJ14 phone jacks for the telco interface.
Figure 17 illustrates the basic connections with the installation interface assembly option.
