Preparation
• Use only a Panasonic Handset for the KX-TG4000B.
• USE ONLY WITH Panasonic AC ADAPTOR PQLV12 (Order No. PQLV12Z).
• The AC adaptor must remain connected at all times. (It is normal for the adaptor
to feel warm during use.)
• The BATTERY indicator lights while the AC adaptor is connected with the backup
battery installed (p. 12).
• If your unit is connected to a PBX which does not support Caller ID services, you
cannot access those services.
