MDW 9031/9031DCP Wireless Pocket Phone Installation and Use
503-801-166 Issue 3 October 1999 15
Positioning a Radio Module or Carrier(s)
Each of your handsets and its corresponding radio module operates within a single zone of coverage:
The range depends on your particular operating environment. For indoor use, walls between the handset and the
radio module will reduce the phone’s range. Avoid concentrations of structural metal, such as steel and
aluminum, and reinforced concrete.
Note: The MDW 9031/9031DCP Pocket Phone has a built-in testing feature
that you can use before final installation to help determine proper
placement of the radio module. To perform the tests, all you need is an
electrical outlet for the radio module and a charged battery pack in the
handset (you do not need a communications system switch/control unit).
The tests are described in “Using Wireless Test Mode” in Chapter 3.
General Positioning
Rules
Failure to observe the following rules regarding location and use will result in
poor performance of your MDW 9031/9031DCP Pocket Phone.
• Position the radio module or carrier(s) in a central location, relative to the
handset(s) usage area, leaving at least 6 feet (1.8 m) between the radio module or
carrier(s) and the communications system switch/control unit or other wired
phones. 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 or carrier(s). The line cord maximum length is 1,000 feet
(305 m) of 26-gauge cable.
• Place the radio module or carrier(s) high on the wall for optimum voice quality
and range. Allow 6 to12 inches (15.2 to 30.5 cm) of space between the top of the
antenna on the radio module and the ceiling.
