T7406 CordlessTelephone
Density and Interference
Each base can support up to 3 handsets. Each base has up to 3
independent time compression multiplexing ( TCM ) line
connections to ports on the KSU / system. To avoid interference,
install only 2 bases and 6 handsets per location.
Each base uses half of the Industrial Scientific Medical ( ISM ) band
for its frequency hopping channels. The dip switches on the base
allow you to assign the base to use either the lower half (902-
915MHz) or upper half (915.1- 928Mhz). Each base must use a
separate half of the ISM band.
If other devices operating on the ISM band interfere with the T7406
base, the other half of the band may be used to minimize
interference. In this situation, install only 1 base station and 3
handsets per location.
