SECTION ONE
INTRODUCTION
1.0 GENERAL
This document is the Operating Manual for the Model 1225 Hand Held Transceiver produced by Applied
Technology Solutions, Inc. The Model 1225 is one component of the Voice Privacy Low Probability of Detection (VPLPD)
System 1200. Other System 1200 components include the Model 1245 Monitor System and the Series 1250 Transmitters.
The System 1200 uses spread spectrum modulation to provide secure, low probability of detection and
interception communications to the user. The transmitted voice data is scrambled with a user selected key, to provide voice
privacy and an additional level of security. The System 1200 employs an ATS proprietary self-synchronizing design. This
design provides nearly instantaneous receiver synchronization and provides improved performance over other spread
spectrum designs in a rapid fade, multi-path environment.
The Model 1225 Hand Held Transceivers can be used for direct communications with other System 1200
devices.
