3.0 Installation
A Quick Installation Guide, which provides an overview of the Radar Monitor
installation procedure, was included with this product.
The following sections of this manual explain in detail the site selection and installation
process:
3.1 Radio Installation Guidelines
The Centeron® Radar Monitor contains sensitive measurement circuitry and a radio
transmitter. Large metal objects such as buildings and vehicles may affect the
transmission of radio signals. Electrical equipment may produce electronic noise that
could adversely affect signal quality.
§ Direct line of sight between the Centeron® Monitor and Controller will provide
optimum radio reception.
§ The Centeron® Monitor and Controller can communicate at distances up to one mile
under optimum line-of-sight conditions.
§ When obstructions such as walls, buildings, and vehicles exist between the
Centeron®
Monitor and Controller the distance between these units should be limited
to less than 500 feet.
