4-4. Checking After Adjustment

To check the values after adjustment, turn off the camera
once, then remove the commander and the commander
relay tool from the camera. Then turn it on again before
checking.

4-4-1. Checking INT VCXO Adjustment

1. Set a DIP switch on highest of the rear panel of the
camera to INT position. (SSC-DC314/DC318P)
2. Slide the sliding switch (S301) on the camera MB
board to connector side (CN301).
3. Confirm that the INT VCXO (CN301, pin-10) frequency
is within the specification.
4. After the checking, slide the sliding switch (S301) on
the camera MB board to IC side (IC305).
