ATTENTION
False detection may occur in the
following situations.
• Angled or sloped walls or objects may
deflect the ultrasonic signal.
• Soft fabrics, carpeting or padded sur-
faces may absorb the ultrasound and
not give an accurate reading.
• Buildings with staggered walls or
insets may also absorb or deflect the
signal.
• Heavy Rain, dirty or damaged sensors
may also cause false warnings.
SENSOR MAINTENANCE
Do not wash the sensors with a
pressure washer or scrub them forcibly.
Avoid wax or grim buildup in the
sensors. Wash the sensors with water in
a low pressure manner.
Please allow the ice to melt by
applying water when sensors are
covered with frozen ice.
