Introduction

1.4 Guided Tour

1.4.1 Construction

The Receiver is constructed using a screened fan-ventilated chassis. All
operational inputs and outputs are via the rear panel connectors. The unit
may be operated free-standing on a horizontal flat surface, or mounted in
a 19-inch rack. 1RU rack height is required. It is important that horizontal
airflow is not obstructed, to maintain the airflow required to cool the unit.

1.4.2 Front Panel Controls

Overview

The front panel is fitted with a keypad that is used to set up and monitor
the unit. Information on the use of these controls is given in Chapter 3,
Operating the Equipment Locally. Figure 1.2 gives an overview on how to
navigate the menus. Figure 1.3 explains how to edit these values once a
menu item is selected.
