General Installation
52 Installation Manual
Note
*"8EXTN" in the table indicates an extension expansion area for 8-Station Line Unit
(KX-TD170) or 8-Station Line Unit with SLT CID (KX-TD171).
System Programming is required for card location identification.
• 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 5.1.1 Installation and
5.1.2 Connection.
• Up to four DSS Consoles (KX-T7440, KX-T7441, KX-T7240 or KX-T7040) can be
installed per system. As the DSS Console itself cannot work alone, it always requires a
proprietary telephone used in pair. Place the DSS Console and the paired telephone side by
side on your desk.
• It is necessary to designate the jack numbers of paired DSS Consoles and proprietary
telephones by system programming.
• After completing all the required inside cabling, including outside lines, extensions,
external pagers, external music sources, doorphones and door openers fasten the cables
with the nylon tie (included) as shown.
