Model 117A4 Carrier Installation Instructions
503-801-1808 Issue 2 February 1999
Positioning Your Carrier(s)
Each carrier holds up to six radio modules. Each radio module and its corresponding handset operates within a
single zone of coverage.
The range of your handset(s) 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.
The MDW telephones have 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).

your site.
