Safety Summary
The following general safety precautions must be observed during all phases of operation, service,
and repair of this product. Failure to comply with these precautions or with specific warnings
elsewhere in this manual violates safety standards of design, manufacture, and intended use of the
product. SolaCom assumes no liability for the customer’s failure to comply with these requirements.
Ground the equipment
To minimize shock hazard, the equipment switch must be connected to an electrical
ground. The equipment has a three-conductor AC power cable. This power cable
must be plugged into an approved three-contact electrical outlet with the grounding
wire (green) firmly connected to an electrical ground at the power outlet. The power
cables meet International Electrotechnical Commission (IEC) safety standards.
Keep away from live circuits
Operating personnel must not remove modules or otherwise tamper with the
equipment switch or related components. Component replacement and internal
adjustments must be made by qualified maintenance personnel. Do not replace
components with the power cable connected unless the component is hot-swapable.
To avoid injuries, always disconnect power and discharge circuits before removing
equipment shelves or making major modifications.

iv
Do not service or adjust alone
Do not attempt major component replacement, internal service, or adjustment unless
another person, capable of rendering first aid and resuscitation, is present.
Replacement of modules
Replacement of modules should be performed by qualified maintenance personnel
(those who have been trained and certified by SolaCom).
Electrostatic discharge (ESD)
This product contains components that can be damaged by electrostatic discharge.
You must take precautions when handling modules. As a minimum precaution, use
grounded wrist straps at all times when handling modules.
Do not modify the product
Do not install substitute parts or modify the product. To ensure that product integrity
is maintained, contact the SolaCom Customer System Support & Services Centre for
any service or repair.
Power surge advisory
Electrical surges (typically lightning transients) are very destructive to customer
terminal equipment connected to AC power sources. We recommend that you install
AC surge arrestors in outlets to which any equipment is connected.

Position and Audio Control Module User Guide
2 Operation
The SolaCom PAC (Position and Audio Control) module is a device that enhances the audio
functionality of LibertySHIELD applications at operator position workstations. It also connects
headsets or handsets via dual-prong jack boxes, offering superior durability compared with USB
devices. The PAC provides two modes of operation: Radio Bypass mode, and Call Taking mode.
2.1 Radio Bypass Mode
In Radio Bypass mode, the PAC module allows an operator (plus an optional
supervisor) to take phone calls from a LibertySHIELD application and radio calls
from a radio dispatch console with a single headset or handset. The audio and PTT
signals are sensed and the shared headset/handset is managed as follows:
•Radio is usually continuously connected to the headset/handset.
•Phone is also usually connected to the headset/handset, although ring and audio
can be switched to speakers by the operator or the LibertySHIELD application.
•When there is an active phone call, audio from the radio bypasses the headset and
instead connects to an auxiliary PAC speaker for continuous monitoring. The
headset/handset remains connected to the active phone call, but when the operator
presses the PTT switch, the microphone on the headset/handset temporarily
switches to the radio, and the telephone call is monitored via USB speakers.

Operation
2.2 Call Taking Mode
In Call Taking Mode, there is no radio connection. The audio sensing of the PAC
module is used to trigger a relay closure whenever a phone call is answered,
providing “recorder active” signals and a 600 ohm analog link for local voice
recording (see Section 2.3).
2.3 Voice Recording
Voice recording is achieved by capturing the audio of phone calls (and, if available,
radio communication) and sending it to a local recorder. Operators can then usually
access portions of the recording (Instant Retrieval) on demand.
Phone audio is sent along with a signal that triggers on the presence of a phone call
so that recording takes place only when a call is answered. Radio audio is sent
continuously and must rely on VOX detection within the recorder.
