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

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.

rectly in a location where there is a

large amount of infrared light.
