The DV-I+ may also be programmed with “special” speed sets. A list of special speed sets is
included in Appendix F. Please consult Brookfield Engineering or your local dealer/distributor
for any special speed requirements not addressed by the standard or special speed sets.

area to the right of RPM (on the bottom line) to display the currently selected speed. Figure II-
8 shows the DV-I+ had been operating at 10 RPM, and the current selected speed is 10 RPM.

NOTE: The speed selection process remembers the last value of scrolled-to speed so that
the next time you initiate a speed change (by pressing an
ARROW key), the DV-
