6. Installation
The RF320 radio is delivered pre-configured for operation. No user
configuration or adjustments are required. Whether located at a base, repeater,
or remote site, installation is a straightforward process. However, careful
attention to detail and an adherence to best practices will help to improve
reliability and reduce maintenance.
6.1 Mounting
The mounting bracket attached to the radio is designed to align with a one-
inch-on-center hole pattern and provides for ridged mounting of the radio in
either a vertical or horizontal orientation. Four #6-32 x .375 inch SS Phillips
head screws (CSI# 505) and four nylon grommets (CSI# 6044) are supplied for
securing the radio to the backplate of a Campbell Scientific enclosure.
