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 the unit,
perform the adjustment using controls RV352 (STAIR
STEP POSITION) and RV353 (STAIR STEP LEVEL) on
the RC-86 board panel of the unit. 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-
700A/750, RCP-740/741, etc.
2. Adjust the position of the signal to be displayed using
control RV352 (STAIR STEP POSITION) on the RC-
86 board.
3. Use control RV353 (STAIR STEP LEVEL) on the
RC-86 board so that the intervals of signals A and B to
be displayed are almost equal.

Press the SEQ button of the WAVEFORM MONITOR
button (or the MONITOR SELECT button) of the MSU-
700A/750, RCP-740/741, etc., to output the waveform
monitor control signal of the unit, synchronizing with the
output signal of the WF output connector.

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 S351 (SEQ) on the
RC-86 board.
If adjustment is not possible even after the polarity is
changed, perform the adjustment on the waveform monitor
side.
