1-6 Introduction: Control Head Descriptions
• Display — The vacuum fluorescent (VF) display’s primary function is to display mode numbers,
mode names, volume level, and the status of options. It also functions as an on-off indicator for
the entire system and plays an integral role in the operator’s reconfiguration of options. The
display is 8 characters on W4, W5, and W7 models; 11 characters on the W9 model.
• XMIT and BUSY Indicators — The XMIT indicator lights when the radio is transmitting. The
BUSY indicator lights when the selected channel is busy.
• Scan Indicators — When scan operation detects activity on a non-priority (NON-PRI) channel,
the NON-PRI indicator light comes on. Activity on a second priority channel causes the priority
(PRI) indicator to light. First priority channel activity causes PRI to flash.
