Headset base and handset lifter installation

Cord labels

The cords provided with your headset are attached with colored
labels to help you plug them into the correct jacks on the
headset base. Each jack on the headset base is labeled and
marked with a colored dot, allowing you to plug in the correct
cords by matching the colors.
If you are using installation option 1, you can attach the
provided light blue colored label to the end of the curly handset
cord of your telephone that you plug into the headset base.
Digital subscriber line (DSL)
If you subscribe to high-speed Internet service (DSL - digital
subscriber line) through your telephone line, you must install a
DSL filter between the telephone base and the telephone wall
jack. The filter prevents noise and caller ID problems caused by
DSL interference. Please contact your DSL service provider for
more information about DSL filters.
