Transcription

1 Monterey County 43L20/43L21/43L18 COMMUNICATIONS TECHNICIAN I/II/III DEFINITION Initially under general supervision, then under direction as experience is gained, installs, maintains, diagnoses and repairs a variety of fixed and mobile electronic communications equipment, including radio transmitter/receivers, antenna systems, microwave equipment, and dispatch console equipment; designs and builds new or revised communications equipment; and performs other related duties as required. DISTINGUISHING CHARACTERISTICS Communications Technician I Communications Technician I is the entry level in the class series. Incumbents install, maintain, and repair communications equipment requiring basic knowledge of technical theories of electronic circuitry, such as radio transmitters, receivers, and speakers and microphones. Incumbents initially work under close supervision and perform the least complex assignments; as experience is gained, employees work with greater independence performing a broader range of duties. Communications Technician II Communications Technician II is the journey level in the class series. Incumbents perform a full range of duties independently under minimal supervision including maintaining and repairing more complex analog and digital radio and microwave communications equipment, utilizing more complicated test equipment, exhibiting additional planning and coordination skills, and maintaining and repairing dispatch console equipment. Communication Technician II may be assigned to perform a considerable amount of work in the field at remote transmitter locations and at various other locations throughout the County. Communications Technician III Communications Technician III is the advanced journey level in the class series. Incumbents independently perform as experts in one or more of the following areas: analog and digital mobile and base radio transmission equipment, microwave systems, dispatch console systems, or other similarly complex equipment. Communications Technician is a flexibly staffed series. Incumbents may be appointed to the next higher level upon meeting the requirements of the higher position and with the recommendation for promotion by the appointing authority. The Communications Technician series is distinguished from other information technology Technician series, such as Information Technology Support Technician, Telecommunications Technician, and Telecommunications Specialist, in that the Communications Technician series has full responsibility for electronic communications equipment with a focus on digital and radio analog systems and the design of complex radio communications systems.
