These telephones also have a red Message light and a Volume control button.
With the 6424D+ and 6424D+M telephones you can access 12 features with the
softkeys and display control buttons. These 12 features can be used
in addition to
the features on the call appearance/feature buttons.
NOTE:
The 6424D+ and 6424D+M telephones can work ONLY in a 2-wire
environment. For more information, see “Wiring Information.”
An XM24 expansion module can be connected to any 6424D+ or 6424D+M
telephone to expand the number of buttons you can use. However, when the
expansion module is connected, you must connect an auxiliary power supply to
the telephone. An 1151A1 local power supply or an 1151A2 local power supply
with Battery Holdover are recommended.
Only the Modular 6424D+M
In June, 1999, Modular 6416D+M (6416D02A) and 6424D+M (6424D02A)
telephones will also be available. These modular telephones allow you to install a
100A Tip/Ring module in the desktop stand on the telephone for increased set
functionality. Through a 6-position RJ11-type jack, the Tip/Ring module provides
connection between these two 6400 Series telephone models and such analog
adjuncts as answering machines, fax machines, modems, analog speakerphones,
and TDD machines commonly used by the hearing impaired.
NOTE:
In order for the Modular 6416D+M and 6424D+M sets to operate, you must
connect an auxiliary power supply to the telephone.
For more information about the 100A Tip/Ring Module, refer to “The 100A
Tip/Ring Module” in the Adjuncts section later in this manual.
