Connection details for the 3106C and 3107C Cordless Telephones are
included in the Cordless Telephone Guide. The guide also covers each of
the accessories that are shipped with the telephone. See
Table 29 and the
installation notes that follow for installation guidelines.
Cordless Telephone Installation Notes
■
Because of radio frequency issues, you can install a limited number of
cordless telephones in one location. In an ideal environment, up to 10
cordless phones can be used in the same environment. For
installations of three or fewer cordless telephones, 3Com
recommends that you use 3107C Telephones. For installations of 3 to
10 cordless telephones, 3Com recommends that you use 3106C
Telephones.
■
Table 29 shows the telephones’ range (the distance between the base
unit and the telephone) under ideal conditions. The actual range
depends on environmental factors such as building structure, size of
the room, RF interference, and other electronic equipment installed in
the same area. A higher location for the base unit reduces the factors
that can interfere with the coverage area.
■
Place the base unit in the center of your coverage area. If the phone
will be also used in the outdoor area, install the base unit an area close
to the window.
■
For best performance, make sure you have at least five meters of
space between base units and that each base unit antenna is raised to
the vertical position.
■
Avoid placing the base unit in a location surrounded by metal surfaces
or near a PC, a monitor, or a telephone.
