Cable technicians generally start out as cable system installers. Installers prepare a subscriber's home for cable reception by connecting the cable system to one or more televisions or one or more computers for high-speed Internet service. Installers explain to subscribers how to use the cable system and how they can upgrade or downgrade their services. If a customer no longer wants the cable system, the installers remove it. Installers may also be responsible for maintaining power lines, which connect the main cable to small groups of homes, and the downsides, which are cable lines to a subscriber's home. Installers typically do light troubleshooting work when customers have minor problems with their cable drives.
