Positioning A Single Radio Module Or The Carrier Assembly - AT&T MDW 9000 Installation Manual

Positioning a Single Radio
Module or the Carrier Assembly
This phone uses radio transmissions to communicate. The range
depends on your particular operating environment. For indoor use,
intervening walls will reduce the phone's range. Try to stay away
from concentrations of structural metal, such as steel and aluminum,
or reinforced concrete.
IMPORTANT:
This phone has a built-in testing feature that you can use before
installation to help determine proper placement of the radio
module. To perform the test, all you need is an electrical outlet for
the radio module and a charged battery in the handset (you do
not need a communications system switch/control unit). Refer to
"Wireless Test Mode" later in this booklet for details.
Before you install the radio module/carrier assembly, note the following
considerations regarding its location and use:
When positioning the radio module/carrier assembly, try to place
the unit in a central location, relative to the handset(s) usage area.
For convenience, you may want to place the radio module/carrier
assembly in the same room, and on the same wall, as your com-
munications system switch/control unit. If your switch/control unit is
located in a remote location, you may have to run a telephone line
cord from your switch/control unit to the centrally positioned radio
module/carrier assembly. The maximum distance is 1000 feet (333 m)
of 26 gauge cable.
At least 6 feet (2 m) is required between the radio module/carrier
assembly and the communications system switch/control unit.
You can install a single radio module in a remote location using a
telephone line cord to connect the radio module to the communi-
cations system switch/control unit. IROBs should be used for out-
of-building installations.
The radio module/carrier assembly should be placed high on the
wall for optimum voice quality and range. Allow at least 1 1/2 feet
(45.7 cm) of space between the top of the antenna on the radio
modules and the ceiling.
