       POWER Button - Press to turn the power on.  The POWER indicator
                      lights.  Press again to turn power off.  POWER must
                      be on when using the Special Effects Switcher.
                      There is no pass through signal when the powr is
                      off.

   DURATION Control - Use to adjust the length of time required to
                      complete an AUTOMATIC FADE-OUT and FADE-IN with a
                      preset wipe pattern.  The duration time is set for
                      0.5 second at the MINimum position.  When you turn
                      the control clockwise, it increases to about 4
                      seconds, at the MAXimum position.

                      This control works only when the unit is in the
                      automatic operation mode, with the MANUAL
                      indicator off.

MANUAL FADE Control - Controls manually a fade-in (wipe-in) and fade-out
                      (wipe-out).  This control works only when the unit
                      is in the manual operation mode with the MANUAL
                      Indicator lit.

                      Press the MANUAL switch and turn the control
                      counterclockwise toward OUT to fade out the picture
                      and sound simultaneously.  Turn the control
                      clockwise toward IN to fade in the picture and
                      sound.

    FADE A/B Switch - a.  In the automatic mode, it performs a fade-out
                          of the present source and fades in the other
                          source.

                      b.  In the manual operation mode, use it to select
                          the option of fading in the other source after
                          the completion of a manual fade out.

        FADE Switch - a. In the automatic mode, pressing the switch
                         once, fades out the present source.  Pressing
                         it again, will bring the same source back.

                      b. In the manual operation mode, when the FADE
                         A/B switch is not used, it fades in the same
                         source after the manual fade out.

  Source Indicators - Light turns on to show which source VCR is being
                      recorded.

      MANUAL Switch - Selects either the automatic or the manual
                      operation mode.  In the manual mode, the MANUAL
                      LED lights and you can control the fade or wipe
                      with the MANUAL FADE control.  In the automatic
                      operation mode, set the DURATION control for the
                      desired length of time of a fade or wipe.

      SOURCE Switch - Press to select the source from the inputs
                      connected to the A and B INput jacks.

                      The source indicators, A and B, above the FADE
                      A/B switch show you which source is presently
                      selected. Each indicator flashes when its source
                      is being faded in or faded out.

Note:  A one-frame flash on the screen will be seen as the unit switches
       sources, because the newly selected source is not yet locked in.

       Wipe Buttons - Use these four Wipe buttons together with the
                      DIAG-H/V (DIAGonal-Horizontal/Vertical) Switch to
                      create the desired wipe pattern.  The LED above each
                      switch indicates which switch is being used.  The 
                      LED lights when the corresponding switch is active, 
                      and it flashes during the wiping process.  Refer to
                      "Wipe Patterns" for a variety of patterns created by
                      these switches.

  DIAG-H/V Selector - Selects the mode for the wipe buttons.  DIAG selects
                      the diagonal wipes that proceed diagonally from
                      corner to corner.  H/V selects the wipes that
                      proceed from top, button and sides.
