Is there an override switch to suppress the audible alert signal?
Some backup warning systems are fitted with an override switch which can defeat the alert buzzer in the event of a persistent nuisance alarm. The Guardian Alert system does not have an override switch, or any type of user adjustments. Relying upon Doppler radar technology to report only diminishing distances between the sensor and an obstacle behind the vehicle minimizes nuisance notifications and obviates the need for an override switch.
