Installation PreparationInstalling the NSQ412 is easy as long as you do a little planning before starting. Locate each station within ten feet ofan a. c. power outlet and seven feet of the telephone jacks. The maximum amount of telephone wire that can bebetween two stations is 600 feet.IMPORTANT: Taking full advantage of the system features requires that the telephone number connected to Line 1 bethe same on all stations. If this is not done, the Privacy, Intercom, Page and Transfer will not work properly. In addition,it is strongly recommended that no other devices operate on Line 1 besides the NSQ412 stations. Any interference on itcan degrade the system performance. The system can be used on a DLS line if either: 1) Line 1 is not the DSL line; or2) Line 1 wiring connected to all stations is behind the DSL filter port.There are many different wiring configurations that a telephone jack can have. The station will support both a home run(the phone line is run from a connecting block to each station) and daisy chain (the phone line is run from one phone tothe next) wiring configuration. Many older homes and businesses have just one telephone line on each jack. Newerhomes and businesses typically have two or three lines per jack. You must identify how your telephone jacks are wiredbefore connecting them to the NSQ412. If you cannot determine this, call your telephone service provider for assis-tance.It is a good idea to document the phone wiring for each NSQ412 location. This can be done using the following worksheet. Record the telephone number for each line and the jack it is found on for each station.NSQ412 Four-Line Caller ID Telephone Owner’s Manual 10DSL
