Plug in the AC Adaptor and the telephone line cord to the rear of the unit. Then connect the cord as
shown.
USE ONLY WITH Panasonic AC ADAPTOR PQLV1CEZ.
●The AC Adaptor must remain connected at all times. (It is normal for the adaptor to feel warm
during use.)
●This telephone has a single terminal which must be connected to an analog line with a RJ11
connector.
●If your unit is connected to a Telephone line or PBX which does not support Caller ID services,
you cannot access those services.
●The telephone will not work during a power failure. We therefore recommend you use a standard
telephone and automatic change-over switch to connect this Digital Cordless Phone to the line.
Your Panasonic Sales Shop can offer you more informationabout connection possibilities.
