    5.0 Troubleshooting Flow Chart for DC Supply (1 of 2)
    Since the failure of a critical voltage supply might cause the radio to automatically power down, 
    supply voltages should first be probed with a multimeter. If all the board voltages are absent, then 
    the voltage test point should be retested using a rising-edge-triggered oscilloscope. If the voltage is 
    still absent, then another voltage should be tested using the oscilloscope. If that voltage is present, 
    then the original voltage supply in question is defective and requires investigation of associated 
    circuitry.

    1.1 UHF2 and Controller Circuits
    The UHF circuits are contained on the printed circuit board (PCB) which also contains the Controller 
    circuits. This Chapter shows the schematics for both the UHF circuits and the Controller circuits. The 
    PCB component layouts and the Parts Lists in this Chapter show both the Controller and UHF circuit 
    components. The UHF and Controller schematics and the related PCB and parts list are shown in 
    the tables below.
