The Unity Two-Line is a powerful telephone with many features
such as automatic dialing and a built-in speaker for call monitor-
ing. Therefore, your telephone is equipped with a transformer for
the power needed to enable these additional features.
To
prevent
accidentally turning off power to your phone, we recommend
using an outlet that is not controlled by a light switch.
Note: Make all cord connections before plugging the power trans-
former into an AC outlet.
