TX MODULATION

The TX Modulation Window, shown in Figure 5, is accessed by

selecting F1 Calib from the Maintenance Screen and then F1 Next or F2

Prev until the window appears. This window allows the user to align the

Transmit Modulation setting across the band. There are six input fields on

this screen: Low, Mid, High, Talk Around Low, Talk Around Mid, and

Talk Around High. The frequencies represented by these settings can be

viewed/edited by returning to the main screen (F10 Back), and pressing

F4 Freq.

Upon pressing F4 Tx On, the programmer will put the radio into

transmit mode. The screen will display a blinking field, "TRANSMITTER

ON", to indicate that the radio is transmitting. The radio will remain in

transmit mode until F4 Tx Off is pressed, or the timeout period (about 2

minutes) has been exceeded. If the timeout period is exceeded, the screen

will display a blinking field, "TRANSMITTER TIMEOUT", for a short

period of time and the transmitter will be turned off.

NOTE

While adjusting the radio, DO NOT disconnect the radio from

the PC interface at any time.
