DCT1000 Installation Manual
Section 2
Overview
In this section you will find illustrations and tables showing the features of the front and rear
panels of the DCT 1000 cable terminal. Before beginning the installation process, please take
the time to familiarize yourself with the various controls and displays.
Front Panel Controls and Displays
The front panel, illustrated below, contains selection buttons, tuning buttons, various displays,
and the power switch. These controls are designed to provide a minimum, but functional,
capability in the event that the cable terminal remote control is lost or is temporarily out of
service. However, certain functions (for example, those requiring numeric entry) are not
available without a remote control.
