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 RV303 (STAIR
STEP POSITION) and RV304 (STAIR STEP LEVEL) on
the RC-91 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 RV303 (STAIR STEP POSITION) on the RC-
91 board.
3. Use control RV304 (STAIR STEP LEVEL) on the
RC-91 board so that the intervals of signals A and B to
be displayed are almost equal.
