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. 1.1SPECIFICATIONS The specifications for the Model 1225 Transceiver follow.

The training is provided as a lecture with extensive question and answers. Training also includes hands on demonstrations. The class normally takes approximately 4 hours and the class size is limited. The training material previously submitted is presented to the class in its entirety. As shown, this material includes information pertaining to controlling exposure limits. This material and the Operating Manual is provided to each attendee.
