Note
• "8EXTN" in the table indicates an extension expansion area for 8-Station Line Unit (KX-
TD170). System Programming is required for card location identification. <SYS PRG
[109]>
• If a telephone or answering machine with an A-A1 relay is connected to the main unit, set
the A-A1 relay switch of the telephone or answering machine to OFF position.
• Mis-connection may cause the system to operate improperly. See 6.1.1 Installation and
6.1.2 Connection.
• Up to four consoles (e.g. KX-T7540) can be installed per system. As the console itself
cannot work alone, it always requires a proprietary telephone used in pair. Place the console
and the paired telephone side by side on your desk.
• It is necessary to designate the jack numbers of paired consoles and proprietary telephones
by System Programming. <SYS PRG [007]>
• After completing all the required inside cabling, including outside lines, extensions,
external pagers and external music sources, fasten the cables with the nylon tie (included)
as shown.
