FCC Statement (Part
Interference
The Call Stacker generates and uses radio frequency energy
and if not installed and used in strict accordance with the manufacturer's instructions, may cause interference to radio and
television reception. Testing is being conducted for compliance
with the limits for a Class B device in accordance with the
specifications in Part
D.O.C. regulations. This testing is designed to provide reasonable protection against such interference. However, there is no
guarantee that interference will not occur in a particular installation. If this equipment does cause interference to radio or
television reception, which can be determined by turning the
Call Stacker unit off and on, the user is encouraged to try to
correct the interference by one or more of the following
measures:
- Reorient the radio or TV receiving antenna.
- Relocate the Call Stacker unit with respect to the radio or
TV receiver or vice-versa.
- Plug the Call Stacker unit into a different outlet so that it and
the radio or TV receiver are on different branch circuits.
If necessary, the user should consult the dealer or an experienced radio/television technician for additional suggestions. The
user may find the following booklet, "How To Identify and
Resolve Radio-TV Interference Problems," helpful. This booklet
was prepared by the Federal Communications Commission
(FCC) and is available from the U.S. Government Printing
Office, Washington, DC 20402. Stock order No. 004-00000345-4.

Overview 1-1
Introduction
The Call Stacker is a microprocessor based audio
recording and announcement system. The Call Stacker is used in conjunction
with a paging system to provide buffered announcement play to the paging
system.
Figure 1-1. Call Stacker Unit
NOTE: Associated
equipment would need
to be powered by an
uninterrupted power
supply.
The Call Stacker features 5 Input Station (recording) channels, a single Page
Output channel and 3 minutes of recording time.
Up to 5 announcements can be recorded simultaneously, virtually eliminating
frustrating delays encountered when accessing the paging system. The recorded
announcements are queued in order so the first announcement recorded that has
hung up, plays first, followed by the second announcement, etc.
The Call Stacker allows users to verify their announcements before they play to
the paging system. If a user is not content with their recorded announcement,
they can re-record it repeatedly until they are satisfied.
The Call Stacker's Page Output channel interfaces to the paging system's control
unit. Once an announcement is recorded, the Call Stacker plays the
announcement over the Page Output channel to the paging system. While the
recorded announcement is playing, the Page Output channel provides a contact
closure to the paging system.
Once the complete recorded announcement plays to the paging system, it is
erased from the Call Stacker, freeing up the recording time for new
announcements.
The Call Stacker can be configured to record and play back paging zone
selection signals. Between 2 and 4 DTMF digits can be entered prior to recording
an announcement which, upon output, precede the recorded announcement and
select the paging system's paging zone.
The Call Stacker is equipped with battery backup which allows it to operate for up to
two hours, from a fully charged battery, if a power failure occurs.

analog station inputs on the telephone system through FCC/DOC approved
modular jacks.Connect the Call Stacker's Page Output channel to the paging
system as shown in Figures 2-4 and 2-5 through an FCC/DOC approved modular
jack. The control contact signal is used to secure and release the paging system

Operation
Recording Announcements
Voice Prompts Enabled
NOTE: If the number of
digits in the paging
zone is set to 0 (see
Table 2-1), the Call
Stacker answers the
trunk and responds
“Start recording, press
the pound key to end or
hang up (Empieze a
grabar el mensage,
para terminar la
grabación cuelge o
marque la tecla de
numero)” followed by a
high tone. Skip step 2
and proceed to step 3.
IMPORTANT: If all the
recording time is used
up, the Call Stacker
answers the trunk and
responds with “No
recording time
available (No hay
