Adjusting the Staircase Signal
Adjust the staircase signal to display signals in the sequen-
tial mode on the waveform monitor. If the signal of the
sequential mode is not normally displayed on the wave-
form monitor, perform this adjustment.
When the waveform monitor is connected to HDCU1000/
1080/1500, perform the adjustment using controls RV301
(STAIR STEP POSITION) and RV302 (STAIR STEP
LEVEL) on the EN-159A/159B board of the HKCU1001/
1003. When the VCS-700 is connected, refer to the VCS-
700 Maintenance Manual.
1. Press the SEQ button of the WAVEFORM MONITOR
buttons (or MONITOR SELECT buttons) of the MSU-
900/950, RCP-750/751, etc.
2. Adjust the position of the signal to be displayed using
control RV301 (STAIR STEP POSITION) on the EN-
159A/159B board.
3. Use control RV302 (STAIR STEP LEVEL) on the
EN-159A/159B board so that the intervals of signals
A and B to be displayed are almost equal.

The control method of the sequential mode depends on the
waveform monitor used. If required, change the polarity of
the control from the setting of switch S411 (SEQ) on the
AT-167 board.
If adjustment is not possible even after the polarity is
changed, perform the adjustment on the waveform monitor
side.
