[Procedure]
1. Press the CX key and shift to the MPP Offset Readjustment.
(Press the AUTO SPACE 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 SCAN key so that TE offset becomes zero.
4. Press the SEARCH key to register the adjustment.
