( ) Pull a few drawbars of the lower manual.
( ) Push the connector for plug 4 on the right preamplifier onto the pins.
( ) Set the volume control " L/Man" about mid-way.
( ) Hold a chord on the lower manual and alternate the positions of the tongue
tab " Drawbars/Fixed Stops" of the lower manual. You should hear the drawbar
sound with the switch in the "up" position and the fixed stops in the "down"
position.
( ) Turn on all fixed stops of the lower manual. Pull XI
out all drawbars of the lower manual.
( ) Hold down a key or chord on the lower manual. Alternate between drawbars

( ) Push the 3 connectors from the harness G O 3 onto the pins o n the
Wersivoice circuit board WV 7.

matching bright sound.
( ) The switches "Fixed Stops to Wersivoice" (in both manuals), when pushed

a rather complex vibrato on the sound such that it seems to emerge from rotating
speakers or baffles.

upper manual. Activate the switch "Wersivoice Left/Right". The sound should
alternate between channels.
