Loudspeaker SP-3
For good acoustic quality, mount the loudspeaker so that it points
toward the user. Mount the loudspeaker more than 50 cm (19.5 inches)
from the driver's or passenger's head. Mount the loudspeaker at least 1
meter (3 feet) away from the microphone to avoid audio feedback.
Connect the loudspeaker to the mono output of the car kit. The car kit
can also be connected to a compatible car radio system; consult your
service technician.
