Setting Up and Operation
Introduction
Setting up the transmitter involves selecting various parameters using the Virtual Front Panel (VFP),
through a Multi-Access Remote Control (MARC) system, from a T6 controller, or from the transmitter’s
front panel. The transmitter can be configured for remote or local use.
Table 9 on page 30 details the functions and parameters that can be set from all these sources.
The rest of this document details how to configure the transmitter from the front panel, and how to operate
the radio in local mode.
Selecting most of the transmitter's operational settings is carried out using the front panel Scroll/Select
switch and the LCD (see the illustration below). No attempt to set up the transmitter should be made until
the transmitter has been installed as per the installation procedures given in the Installation section.
Normal Operation
During normal operation, the LCD displays the Main screen. This screen shows the operating frequency,
the channel number (if the channel store facility is used), the carrier offset (if used), and displays a
graphical representation of output power when the transmitter is keyed. If the transmitter has been set to
Standby mode, which is shown by the front panel Standby indicator being lit, the LCD is blanked.
Using the Scroll/Select Switch
The Scroll/Select switch (referred to throughout this section as the ‘Switch’) is used to leave the Main
screen and display the Control screen (see page 8). Further use of the Switch displays various selection
menus and allows the required parameters to be set. The switch has three actions: it can be turned
clockwise, anti-clockwise, or momentarily pushed in.
