Rotary changes to FAST uninten-
tionally

Control pedal or D Beam is assigned
to “CRESCENDO.”
If the control pedal or D Beam is as-
signed to “CRESCENDO” when the
[SLOW/FAST] button is in the
SLOW state, and you fully depress
the control pedal, or place your
hand very close to the D Beam, the
rotary will switch to FAST.

If the [SLOW/FAST] button is in the
SLOW state, rocking back onto the
heel of the control pedal, or moving
your hand away from the D Beam
will cause the rotary to return to
SLOW.

Hold pedal or control pedal oper-
ation is reversed

The control pedal’s polarity is re-
versed.

Depending on the type of pedal
switch or expression pedal, it may
have the opposite operation when
depressed. Switch the polarity of the
control pedal.

p. 56

D Beam sensitivity is incorrect

Something was covering the D Beam
when the power was turned on.
When the power is turned on, the
VK-8 automatically adjusts the sen-
sitivity of the D Beam. For this rea-
son, do not place any objects on the
D Beam or cover it with your hand
when the power is turned on.

Readjust the sensitivity of the D
Beam.

tion where there is a large amount of

The D Beam will not function cor-
rectly in a location where there is a
large amount of infrared light.
