The buzzer (PN 1483944) produces a louder audible alert, along with the visual on the monitor, to the presence
of objects in the path of the vehicle. The buzzer is placed in the cab. Discard the black wire, unless you need it to
extend the negative (white) wire. See Figure 28 for buzzer components.
The audible part of the buzzer does not sound until
3 black/white indicator balls are displayed on the
monitor. See Detection Zone Set Up for more
information.
