near a standard 120V AC outlet and telephone line
jack. The base station can also be mounted on a
standard AT&T or GTE wall plate, or directly on a

noise (motors, transformers, fluorescent lighting, or
computers).
Mount the base station and your key telephone at
least three to four feet apart to avoid noise from the
