[Procedure]
1. Press the AUTO/MANUAL key and shift to the MPP Offset Readjustment.
(Press the AUTO/MANUAL key several times to appear the right indication.)
2. Monitor the TE waveform with VC.
Be careful with monitoring TE waveform instead of MPP waveform in the readjustment !
3. Adjust the JOG key so that TE offset becomes zero.
4. Press the ENTER key to register the adjustment.
