Revision 3 5.0 OPERATION 5.1. Basic Front Panel Operations On each screen, a selection cursor appears as an underscore character. This cursor is moved left or right using the respective arrow key. When the desired item has been identified with the cursor, the item is selected by pressing the Enter (ENT) key. Once selected a cursor (underscore) will begin to flash as a solid box. Use the up (4) or down arrows to scroll through the settings.
Revision 3 Using the left and right arrows selects the digit to edit and the up and down arrows to change the digit value. Continue this procedure until the entire frequency has been set. When complete press the ENT key to have the new frequency take effect. if a frequency is entered that is outside of the band of operation an error message will be displayed. The error message will contain the valid region of operation. The invalid frequency entered will be ignored.
Revision 3 mode, the frequency synthesizer is locked on frequency. V. PRES, TOBY: This mode is only delectable if the input is set to VIDEO. If no video is present, the transmitter automatically switches to STANDBY after a two second delay (minimum). This mode is used to remotely place the transmitter info STY when a video signal is removed. if the Test Generator is installed, the user may select Color Bars to be activated rather than having the unit go into STY. See Section 5.3.1. 7.037.
Revision 3 When MIC is selected, the unit will accept a balanced 1-Chm input from -50 to -30 dBm. An internal AGC maintains the average sub carrier deviation at 50 kHz. (67 kHz for PAL). Four LED's (1 through 4) indicate the current status of the audio channels as follows: GREEN Channel is ON and functioning properly. GREEN (Flashing) — Indicates over modulation. RED Trouble indication. OFF — Channel is “OFF” or not provided.

Revision 3 5.3.1. NEWSCASTER VT1 Settings Video Configuration: Video invert and emphasis are edited from this menu. If the NEWSCASTER VT1 is used with existing equipment that causes the video to be inverted, the video can be per-inverted at the transmitter to compensate for the receiver. If desired, the pre emphasis network may be bypassed. £ Video Level: 0 Video Emphasis: ON Pressing the UP or DOWN arrow selects the Video Standby screen. Video Black Standby and Video Standby are selected from this menu.
Revision 3 Audio Sub carrier Screen: Under this screen, the status of the audio sub carriers is displayed, toggling between all of the sub carriers.

Revision 3 6.0 Theory of Operation 6.1. General Theory of Operation The following sections describe the overall transmitter system. Section 6.2 provides a general module description. See Figures 6-1 and 6-2 for the block diagrams. 6.1.1. Internal Communications and Control The NEWSCASTER VT1 includes the latest in technology. Each module within the NEWSCASTER VT1 Transmitter contains a local microprocessor responsible for control and monitoring of the specific module.

All unit controls originate from this control board, The Smart Display contains a microprocessor and a variety of peripheral interfaces. Control and monitoring commands originate from the microprocessor to other modules. The other modules reply with status signals that are displayed on either the LCD or various LED's on the front panel. 6.2.2.
