Operating submarine radio-room equipment in port and underway provides an equipment-use foundation for learning civilian telecommunications installation and repair.

How to prepare: Complete hands-on telecommunications training covering circuit testing, fault isolation, and equipment installation.

What the civilian work involves
  • Test circuits and components of malfunctioning telecommunications equipment to isolate sources of malfunctions, using test meters, circuit diagrams, polarity probes, and other hand tools.
  • Test repaired, newly installed, or updated equipment to ensure that it functions properly and conforms to specifications, using test equipment and observation.
  • Assemble and install communication equipment such as data and telephone communication lines, wiring, switching equipment, wiring frames, power apparatus, computer systems, and networks.
