2.2 DECT radio base stations
2.2.1 Physical description
A DECT base station consists of a plastic housing and an electronic card. The electronic card
manages the ISDN interface. One radio module mounted on the card manages the radio
interface. A DECT base station is equipped as standard with two quarter-wave antennas
integrated into the unit. To obtain polarization diversity, one is horizontal and the other vertical.
Note: You are advised against repainting the housing without written consent from
manufacturer
.
In release 3.2 and later, a new base station may be installed on any F4 and F6 device. The new
base station is physically identical to the old M6241 base station. Only obsolete components of
the electronic card are replaced.

Base stations must be installed vertically. Remove the base station housing by sliding it upwards.
