The danger here is if you set the SOURCE selector to B/W CAMERA with the DXC-1600, the VTR will try to send sync pulses to the camera while the camera is forcing its own sync pulses back into the VTR. As a result, your playback will have a loss of sync line running throughout it constantly—thereby rendering your material useless. Unfortunately, this situation does not show up on the viewfinder while shooting so you aren't aware of the problem until it is too late—on playback.
So, the VTR must be told not to send sync pulses to the camera. This is what happens in the TV/LINE mode. You fool the AV-8400S into thinking it's recording from a monitor or another VTR.
Another problem in color recording is the positioning of the SOURCE selector switch. When connecting the 10-Pin cable to the AV-8400S, it's very easy inadvertently to bump the SOURCE selector switch with your fingers, moving it into the B/W CAMERA position. You should tape the switch in the proper position so it won't get changed accidently.
Step 5 Set the MODE selector to COLOR and reset the tape counter to 000.
Step 6 Install fully charged batteries in the CCU and VTR.
Step 7 Turn on the CCU POWER switch. The pilot lamp will light confirming that the batteries in the CCU and in the AV-8400S VTR are charged. Check the level meter on the AV-8400S and look for the red light on the left side of the camera viewfinder. The red light should be ON-
Step 8 Set the camera WHITE BALANCE- See DXC-1600 Set-Up Procedure, Chapter 13—The Videocassette Portapak
Step 9 Place the VTR in the RECord mode and begin recording- Playback of the VTR Through the Camera Viewfinder
If operating from a 12-volt battery or a car adaptor:
Step 1 Set the SOURCE selector on the AV-8400S to TV/LINE.
Step 2 Set the MODE selector to B/W.
Step 3 Set the CCU VF MONITOR switch to VTR. The indicator lamp will light-
Step 4 Raise the viewfinder screen to observe the playback in the camera-
CAUTION: Be sure to switch the MODE selector on the AV-8400S back to COLOR when pre-paring to record again.
