                        Provisioning the T7406 / 7 Provisioning the T7406 This chapter provides specification and provisioning information for  the T7406 cordless system. The T7406 is a Frequency Hopping Spread Spectrum (FHSS) cordless  telephone. The benefits of this technology are: improved range,  robustness and, less susceptibility to interference, fading and multipath. The use of a common wall-mounted base station for multiple handsets  allows you to position the base antennas for maximum performance and  coverage

                        8 / Provisioning the T7406 Another example is an environment that already contains another 900  Mhz device (e.g. a scanner with 900 Mhz wireless connection to a  LAN). In this environment, only one T7406 base station should be  installed. Set the T7406 base station dip switch to the opposite band  that the scanner is operating in. Installation Site Parameters Physical characteristics of the site where the T7406 is to be installed, or  has been installed, must be evaluated to maximize the perform

                        Provisioning the T7406 / 9 RF LANs (Radio Frequency Local Area Networks) RF LANs are primarily installed in large chain businesses such as retail  and grocery where the RF LAN is used for inventory equipment. With the correct selection of the T7406 operating band, the RF LAN  operating at 900 MHz does not pose an operating issue for T7406 nor  does the T7406 pose issues for the RF LAN with respect to data  transmission capabilities. However, there may be instances where the  T7406 user may hear

The T7406 utilizes premium  1400 mAh NiMh batteries. A fully charged 1400 mAh battery should provide four to five hours of  talk time in a typical eight-hour day over, approximately, a three-year  service life.  The T7406 has been engineered to provide the following talk-time  parameters:   T7406 users should feel comfortable using the hands

For more  information about setting the dip switches, refer to Installing the Base  Station on page 21. If other devices operating on the ISM band interfere with the T7406  base, the other half of the band may be used to try to minimize  interference. In this situation, install only one base station and three  handsets per location. Spare Parts You can order spare parts for your T7406 telephone. For more  inform
