General Instructions (cont’d)
MODE Switches (on front of unit) A set of 5 MODE switches (S1 through S5, see Figure 1 on page 5) is included to
set the power supply voltage, confirmation or pre-announce tone, and VOX
operation. These switches are accessible through an opening in the front cover and
can be moved with a pointed tool, such as the tip of a ballpoint pen. Set the
switches as described in the Specific Instructions (pages 9 - 18).
Power Supply Connections No power supply is required when the UPAM is connected to a PABX station port
(supplying analog ring voltage and approximately 48V of Talk Battery) or Centrex
line. The included power supply will power the UPAM and provide 48-volt talk
battery for trunk port or page port operation. The illustrations in the Specific
Instructions section (pages 9 - 18) show the correct connections from the power
supply to the UPAM module.
Auxiliary Switch Bank Certain options are available (described in Specific Instructions on pages 9 - 18)
(On top of unit) and are selected by setting DIP switches on the AUX switch bank, accessible
through an opening in the top of the UPAM case. See Figure 5 (page 16) for its
location on top of the unit.
Paging System Connections Illustrations showing connection of the UPAM to a typical paging system are
included in Section 3.
Troubleshooting A Functional Test Guide in Section 4 isolates problem areas, if they arise, following
installation.
