4. |
INSPECT REAR TELEVISION CAMERA ASSEMBLY |
(a) Reconnect the V22 rear television camera assembly connector.
(b) Using an oscilloscope, check the waveform of the rear television camera assembly.
HINT:
A waterproof connector is used for the rear television camera assembly. Therefore, inspect the waveform at the radio and display receiver assembly with the connector connected.
OK:
Waveform is similar to that shown in the illustration.
