To connect the cables, first pull the plug off the pin header
upwards. The wires with press-fit wire end ferrules can therefore
be inserted conveniently under the orange opening points without
tools.
The tone signal can be set quieter and louder by replugging the
plugged bridge underneath the connections for the VS-pump. The
plugged bridge can also be removed if necessary. The tone signal
is then no longer available.
