commander and the commander junction fixture from the
camera. Turn off the camera, then turn it on again before
checking.
4-5-1. Checking SYNC Level Adjustment
Check to see if the measured voltage is within the specified
range.
3
Check to see if the AD/-IN value (CN302
2
pin) is
within the specified value range.
