About your T7406 telephone
The T7406 is a multiple-handset, single-base cordless telephone
system. The T7406 telephone provides a fully-integrated mobility
solution for your business. The T7406 handset allows you to freely
move around your work space while on a call, and still maintain access
to all your telephone system features.
The T7406 telephone uses advanced digital frequency hopping spread
spectrum (FHSS) technology to provide a quality audio path over a 900
MHz radio link. Establishing a call over a radio link is comparable to a
wire line communication.
Note: The T7406 cordless telephone is supported on all Norstar systems
(DR3 or higher) and on all Business Communications Manager
systems.

Radio range and coverage considerations

The effective operating radio range in your facility depends on the
building construction and the internal layout of the facility. Typically, a
dense office or warehouse environment has an effective operating radio
range of 95 meters (300 feet). An open office environment enhances
operating radio ranges. Refer to

Security of Conversation

Each base station has a unique Security Code (S.S. Code). All three
handsets registered to the base station must share the same Security
Code. Each of the three handsets assigned to a base station must also
have a unique identification (Set I.D. 1, 2 or 3).

Density and Interference

For this system to be interference-free, install a maximum of two base
stations and six handsets per location. Each base station provides three
independent time compression multiplexing (TCM) line connections to
the telephone system.
Each base station uses half of the Industrial Scientific Medical (ISM)
band for its frequency hopping channels. The dip switches on the base
station allow you to assign the base station to use either the lower half
(902-915 Mhz) or the upper half (915.1-928 Mhz).
